Description

Technology Field

[0001] The present disclosure relates to an apparatus and method for trading securities with a specific user. More specifically, the present disclosure relates to an apparatus and method for performing a transaction of securities by designating a counterparty. Background Technology

[0002] Competitive trading refers to a method of trading financial instruments where a transaction is concluded through mutual competition between multiple sellers and multiple buyers. For example, under competitive trading, a transaction may be prioritized for execution based on factors such as the lower the price a seller places an order at, the higher the price a buyer places an order at, the earlier the request is made, or the larger the requested quantity. In contrast, over-the-counter trading is a method of trading securities through negotiation between a buyer and a seller, unlike competitive trading. That is, under over-the-counter trading, a transaction can be concluded only when the parties agree on the purchase price, quantity, method of transaction, and settlement terms through individual negotiation.

[0003] The over-the-counter (OTC) stock market is a representative example of a trading market where over-the-counter (OTC) trading takes place. In OTC stock transactions, when sellers and buyers directly negotiate price and quantity via phone or messenger and enter into a contract based on the agreement, the actual success rate of the transaction is currently low due to issues such as the buyer receiving the shares first but failing to send the money, or the buyer sending the money but failing to receive the shares. Consequently, services that mediate OTC stock transactions between parties are emerging. Sellers or buyers use OTC stock trading brokerage platforms to post sell or buy notices on the quote board; an unspecified number of people view these posts, and a counterparty wishing to trade can send a request to finalize the transaction. However, in cases where the counterparty is already identified, such as in a transaction with an acquaintance, one can only create a post and urge the counterparty to check the post as quickly as possible and make a request before other users do so. To resolve this inconvenience, there is a need for a method that allows for the trading of securities via over-the-counter trading by designating a specific counterparty. The problem to be solved

[0004] One embodiment of the present disclosure aims to provide an apparatus and method for supporting a transaction in which a counterparty is designated while using a counterparty trading method. means of solving the problem

Specific details for implementing the invention

[0054] To clarify the technical concept of the present disclosure, embodiments of the present disclosure will be described in detail with reference to the attached drawings. In describing the present disclosure, detailed descriptions of related known functions or components will be omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the present disclosure. Components having substantially the same functional configuration among the drawings have been assigned the same reference numerals and symbols as much as possible, even if they are shown in different drawings. For convenience of explanation, devices and methods will be described together where necessary. Each operation of the present disclosure does not necessarily have to be performed in the order described and may be performed in parallel, selectively, or individually.

[0055] The terms used in the embodiments of this disclosure have been selected to be as widely used and general as possible, taking into account the functions of this disclosure; however, these terms may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. Additionally, in specific cases, terms have been selected at the applicant's discretion, and in such cases, their meanings will be described in detail in the description of the relevant embodiments. Therefore, terms used in this specification should be defined not merely by their names, but based on their meanings and the overall content of this disclosure.

[0056] Throughout this disclosure, singular expressions may include plural expressions unless the context clearly indicates otherwise. Terms such as “comprising” or “having” are intended to specify the presence of features, numbers, steps, actions, components, parts, or combinations thereof, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. That is, throughout this disclosure, when a part is described as “comprising” a certain component, it means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0057] Expressions such as "at least one" modify the entire list of components and do not modify the components of the list individually. For example, "at least one of A, B, and C" and "at least one of A, B, or C" refer to only A, only B, only C, both A and B, both B and C, both A and C, all of A, B, and C, or any combination thereof.

[0058] Additionally, terms such as “...part,” “...module,” etc., as described in this disclosure refer to a unit that processes at least one function or operation, and may be implemented in hardware or software, or a combination of hardware and software.

[0059] Throughout the entire disclosure, when a part is described as being “connected” to another part, this includes not only cases where they are “directly connected” but also cases where they are “electrically connected” with other elements interposed between them. Furthermore, when a part is described as “comprising” a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0060] As used throughout this disclosure, the expression “configured to” may be replaced, depending on the context, with, for example, “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to,” or “capable of.” The term “configured to” may not necessarily mean only “specifically designed to” in hardware. Instead, in some situations, the expression “system configured to” may mean that the system is “capable of” together with other devices or components. For example, the phrase “a processor configured (or set) to perform A, B, and C” may mean a dedicated processor for performing said operations (e.g., an embedded processor), or a generic-purpose processor (e.g., a CPU or an application processor) capable of performing said operations by executing one or more software programs stored in memory.

[0061] Throughout the entire disclosure, a terminal or terminal may include a UE (User Equipment), MS (Mobile Station), cellular phone, smartphone, computer, or a multimedia system capable of performing communication functions. Of course, it is not limited to the above examples.

[0062] One embodiment of the present disclosure aims to provide an apparatus and method for supporting securities trading by a direct trading method. For convenience of explanation, over-the-counter (OTC) stock trading is used as an example of securities trading by a direct trading method for the following description; however, the embodiments of the present disclosure are not limited to OTC stock trading and can be applied to all transactions conducted by a direct trading method. For example, a securities trading support apparatus by a direct trading method performing one embodiment of the present disclosure may support transactions of securities, OTC stocks, bonds, foreign exchange, cryptocurrencies, real estate, real estate securitization securities, token securities, etc. If the securities trading support apparatus by a direct trading method performing one embodiment of the present disclosure supports OTC stock trading, it may be named an OTC stock trading support apparatus; if it supports real estate securities trading, it may be named a real estate securities trading support apparatus; and, without being limited thereto, it may be named a support apparatus that supports various transactions conducted by a direct trading method.

[0063] Throughout the entire disclosure, the seller's account refers to an account held by the seller, and the buyer's account may refer to an account held by the buyer.

[0064] Throughout the entire disclosure, transfer processing refers to the act of moving cash, securities, etc., contained in one account to another account. This includes not only the act of a securities trading support device using a counterparty trading method directly moving cash, securities, etc., contained in a user account to another user account, but also cases where the securities trading support device using a counterparty trading method requests a third party, such as a securities company server, to transfer between the accounts of the parties.

[0065] Throughout the entire disclosure, the term "deposit" refers to an advance payment or guarantee related to a transaction, which may include cash, substitute funds, check deposits, etc.

[0066] FIG. 1 is a drawing illustrating a securities trading method using a counterparty trading method according to one embodiment of the present disclosure.

[0067] Referring to FIG. 1, a securities trading support device may generate a bulletin board (110) regarding each security item. The bulletin board (110) may include at least one of a sell order bulletin board and a buy order bulletin board. For example, information such as security item information (e.g., security name, security code, etc.), the estimated market capitalization of the company corresponding to the security, and the market price of the security may be posted on the bulletin board (110). Although the following description focuses on the case where a seller registers sell information and a buyer requests a transaction, including the description of FIG. 1, it is understood that a corresponding embodiment may also be applied when a buyer registers buy information and a seller requests a transaction, and these two cases are substantially identical or equivalent to each other.

[0068] In one embodiment, a securities trading support device may receive a request for the creation of a sell order from a seller's terminal. The request for the creation of a sell order may include information on the type of securities, a desired selling price, a desired selling quantity, and information on the trading method. The information on the trading method may include information on whether to use a secure trading method, information on whether to proceed with the transaction without linking a securities account, etc. In one embodiment, a secure trading method may refer to a trading method in which the securities subject to the transaction and the transaction amount between the seller and the buyer are automatically transferred through a securities company server, and a transaction without linking a securities account may refer to a trading method in which the securities subject to the transaction and the transaction amount are manually transferred between the parties.

[0069] In one embodiment, the securities trading support device may register selling information corresponding to the sell order creation request information received from the seller's terminal on the bulletin board (110). In one embodiment, the securities trading support device may verify the legitimacy of the sell order creation request information and register the selling information corresponding to the sell order creation request information on the bulletin board (110) only when the legitimacy of the sell order creation request information is verified. The case where the legitimacy of the sell order creation request information is verified may be when the seller holds more than the desired quantity of the stock to be sold.

[0070] In one embodiment, the securities trading support device may receive buy request information (120) corresponding to the sell information from a buyer's terminal based on the sell information registered on the bulletin board (110). The buy request information (120) may include stock information, desired purchase price, purchase quantity, total amount, etc. In one embodiment, the purchase quantity may match the desired sale quantity.

[0071] In one embodiment, the securities trading support device checks whether there is a deposit for the purchase quantity in the buyer's account based on the received purchase request information (120), and if there is a deposit for the purchase quantity in the buyer's account, it may provide a consultation interface (130) to the seller's terminal and the buyer's terminal. For example, the securities trading support device may transmit the consultation interface to the seller's terminal and the buyer's terminal, or transmit a request to provide the consultation interface to the seller's terminal and the buyer's terminal, so that the seller's terminal and the buyer's terminal may display the consultation interface to the user. The seller's terminal and the buyer's terminal may proceed with a counterparty transaction through the consultation interface (130). A transaction may be concluded when the intentions of the trading parties match by negotiating the transaction price, transaction quantity, transaction method, settlement conditions, etc., through negotiation between the seller and the buyer. For example, upon successful negotiation through the consultation interface, the securities trading support device may process the transfer of the purchase quantity securities from the seller's account to the buyer's account and the deposit for the purchase quantity from the buyer's account to the seller's account. For example, a securities trading support device may receive passwords for securities accounts from the seller's terminal and the buyer's terminal based on the details of the agreement through the agreement interface, and transmit transaction information to a securities company server. Based on the received transaction information, the securities company server may move a corresponding quantity of securities from the seller's account to the buyer's account and transfer the corresponding deposit from the buyer's account to the seller's account. Additionally, the securities trading support device may transmit transaction execution details to the seller's terminal and the buyer's terminal.

[0072] In the description of FIG. 1, a method of transaction is explained in which purchase request information is received based on sale information registered on a bulletin board; however, a similar process can be used when sale request information is received based on purchase information registered on a bulletin board. According to the embodiments described above, the seller writes a sale post regarding the desired quantity to sell, and the buyer can purchase the securities subject to transaction in a quantity that matches the desired quantity based on the written sale post. However, in such cases, if the desired quantity to sell is relatively large, the buyer may face the burden of having to pay a large transaction amount because they must purchase all of the securities subject to transaction in a large quantity, and the seller may also find it difficult to sell. Furthermore, even if the intentions of the parties coincide, unnecessary time may be consumed as a contract is concluded after negotiations are conducted through a negotiation interface. Additionally, since the transaction is conducted through a bulletin board, the progress of the transaction with a specific party may be unstable.

[0073] Accordingly, there is a need for mechanisms and methods that can support smooth and efficient transactions between sellers holding large quantities and buyers purchasing small quantities, execute transactions quickly by omitting unnecessary procedures, and perform securities transactions even when the trading parties are predetermined.

[0074] FIG. 2 is a flowchart of a method for performing securities trading using a counterparty trading method with a specific user according to one embodiment of the present disclosure.

[0075] Referring to FIG. 2, in operation 210, the terminal (201) of the first user can obtain user input for order generation. In one embodiment, the user input for order generation may include user input regarding stock information of the securities to be traded, user input regarding quantity information of the securities to be traded, user input regarding the desired trading price, user input regarding the trading method, etc. For example, the terminal (201) of the first user can obtain user input regarding stock information such as stock name, stock code, etc., user input regarding quantity information regarding the total quantity that the user intends to sell or buy, and user input regarding the trading method of trading with a specific user by using a platform provided by the securities trading support device (205).

[0076] In one embodiment, quantity information may include information on the total quantity of securities subject to trading, information on whether split execution is possible for the total quantity, information on the minimum quantity available for trading, and information on whether fractional share trading is possible. Here, information on whether fractional share trading is possible may be information that a trader intends to trade at least one share per transaction. Accordingly, information on fractional share trading possibility may imply that the minimum quantity available for trading is one share. Additionally, information on whether split execution is possible for the total quantity may mean that one or more transactions can be performed with one or more trading parties; for example, if the total quantity is 100 shares, it may mean that transactions for the total quantity can be performed through one or more transactions until the total quantity is fully traded, such as 20 shares with a first trading party and 30 shares with a second trading party.

[0077] In one embodiment, the transaction method may include a transaction method called 'transaction with a specific user', a transaction method called 'immediate execution', a transaction method called 'safe transaction', a transaction method called 'conducting a transaction without linking a securities account', etc.

[0078] In one embodiment, the transaction method designated by the first user as 'transaction with a specific user' may refer to a transaction method of an order that is disclosed to specific user(s) rather than an unspecified number of people, such as by designating a trading partner before the first user creates an order or setting the conditions of the created order to be visible only to users designated by the first user, rather than the conditions of the order created by the first user being disclosed on a bulletin board open to an unspecified number of people, such as an order board.

[0079] In one embodiment, the terminal (201) of the first user may obtain user input regarding the first user's intent information (hereinafter referred to as "first user's immediate execution intent information") that a sales contract can be concluded without a separate confirmation process of the first user when certain requirements are met. In one embodiment, the fact that a sales contract can be concluded without a separate confirmation process of the first user may include the fact that, for a securities order containing the first user's immediate execution intent information, a sales contract can be concluded without the first user taking any action after the counterparty requests a transaction, without the first user undergoing a consultation process through the consultation interface (130) described above with reference to FIG. 1 or a process of obtaining additional approval from the first user regarding the conclusion of a sales contract. That is, the separate confirmation process may include the first user's confirmation process from the time the counterparty transmits the transaction request until the conclusion of the contract. In one embodiment, the present disclosure may operate in the same manner as when there is immediate execution intent information even when there is no explicit immediate execution intent information of the first user.

[0080] In one embodiment, the information on the first user's intention to execute immediately may further include a period during which the first user's intention that a trading contract can be executed without a separate verification process is valid when certain requirements are met. According to one embodiment, the securities trading support device can protect the first user in a volatile market by receiving a period during which the first user's intention that a trading contract can be executed without a separate verification process is valid. In one embodiment, the securities trading support device may self-designate a period during which the first user's intention that a trading contract can be executed without a separate verification process is valid. In one embodiment, the securities trading support device may designate a period during which the first user's intention that a trading contract can be executed without a separate verification process is valid as a fixed value (e.g., 5 business days).

[0081] In one embodiment, a secure transaction method may refer to a transaction method in which the securities subject to transaction, transaction funds, etc., of the seller and buyer are automatically transferred through a securities company server, and a transaction without securities account linkage may refer to a transaction method in which a securities trading support device provides contact information and contact methods between the parties, and the securities subject to transaction, transaction funds, etc., are manually transferred between the parties. In one embodiment, only when using a secure transaction method, the user input may include information on the first user's intention to execute immediately.

[0082] In one embodiment, if the securities trading support device includes information on the first user's intention to execute immediately, it may limit the amount for which a trading contract can be executed without a separate confirmation process by the first user. Accordingly, the securities trading support device can protect the parties from unintended contract execution caused by digit errors, etc., during the irreversible immediate execution process.

[0083] In one embodiment, user input containing information on the intention to execute immediately may include information that price negotiation is not possible, or may imply information that price negotiation is not possible. That is, the transaction corresponding to the order creation request containing the first user's information on the intention to execute immediately may be designed so that price negotiation is not possible.

[0084] In one embodiment, certain requirements may include cases where, in a contract corresponding to order creation request information, the quantity the buyer wishes to purchase is included within the range of the quantity the seller wishes to sell, and the price the seller wishes to sell matches the price the buyer wishes to purchase.

[0085] In one embodiment, the user input may further include user input indicating whether price negotiation is possible. For example, if the first user wishes to enter into a contract only at the desired transaction price, the user input may include user input containing information that price negotiation is not possible. As another example, if the first user wishes to receive negotiation regarding the desired transaction price they have specified, the user input may include user input containing information that price negotiation is possible.

[0086] In operation 220, the terminal (201) of the first user may transmit a request to create an order to trade securities with a specific user to the securities trading support device (205). For example, the request to create an order may be created based on the user input obtained in operation 210, which includes user input regarding a trading method, such as trading with a specific user. In one embodiment, the request to create an order may include information on the stock of the securities to be traded, quantity information of the securities to be traded, a desired trading price, information on the trading method, account information of the first user, etc.

[0087] In operation 225, the first user's terminal (201) can transmit order confirmation password setting information to the securities trading support device (205). In one embodiment, the order confirmation password may be a password set by the first user to disclose order information only to a specific user, rather than disclosing it to an unspecified number of people. For example, the first user's terminal (201) can transmit information about a password consisting of four numbers.

[0088] In one embodiment, operation 220 and operation 225 may be performed simultaneously in parallel or sequentially. That is, the order confirmation password setting information may be included in the order creation request and transmitted, and after the order creation request is transmitted, the securities trading support device (205) may receive a request to enter the order confirmation password, and based on the request, the first user's terminal (201) may obtain user input regarding the order confirmation password and transmit information to the securities trading support device (205) to set the order confirmation password.

[0089] In operation 230, the securities trading support device (205) may generate a first order and identification information of the first order corresponding to an order creation request. In one embodiment, if the order creation request is for a sell order, the securities trading support device (205) may determine whether there is a security corresponding to quantity information in the first user's account and may generate a first order based on the determination that there is a security corresponding to quantity information in the first user's account. In another embodiment, if the order creation request is for a buy order, the order creation request includes price information of the securities to be traded, and the securities trading support device (205) may determine whether there is a deposit corresponding to quantity information and price information in the first user's account and may generate a first order based on the determination that there is a deposit corresponding to quantity information and price information in the first user's account.

[0090] In one embodiment, as information regarding the stock, quantity, price, trading method, etc. specified by the first user is included in the order creation request, a first order and identification information of the first order including said order information can be generated. The identification information of the first order may include a link, a deep link, an app link, a deferred deep link, etc. In one embodiment, the identification information of the first order may be transmitted to the terminal (201) of the first user by the securities trading support device (205) and the first user may transmit it to the second user (hereinafter referred to as 'Embodiment 1'), or the securities trading support device (205) may directly transmit the identification information of the first order to the terminal (203) of the second user (hereinafter referred to as 'Embodiment 2').

[0091] The first generated order is an order created to trade with a specific user and may not be displayed on the quote board.

[0092] In operation 240, the securities trading support device (205) can transmit order creation completion information based on the identification information of the first order to the terminal (201) of the first user.

[0093] In ‘Example 1’, the identification information of the first order may be included in the order creation completion information based on the identification information of the first order. That is, the securities trading support device (205) may transmit order creation completion information including the identification information of the first order to the first user’s terminal (201). The first user’s terminal (201) may obtain the identification information of the first order from the securities trading support device (205) and transmit the identification information of the first order to the second user’s terminal (203). For example, the identification information of the first order may be transmitted to the second user’s terminal (203) by the first user copying the identification information of the first order displayed on the first user’s terminal (201) and pasting it into a messenger, chat interface, text message, email, or a 1:1 chat room within the platform provided by the securities trading support device (205).

[0094] In ‘Example 2’, the first user may have identified the second user in advance during operation 220. The first user’s terminal (201) may transmit the second user’s identification information to the securities trading support device (205) together with, or included in, the order creation request. For example, the second user’s identification information may include the second user’s ID, name, unique identifier, phone number, etc. By the first user’s terminal (201) transmitting the second user’s identification information to the securities trading support device (205), the securities trading support device (205) can identify the second user based on the second user’s identification information. In one embodiment, the first user may identify the second user by selecting the securities sending function in a 1:1 chat room with the second user and transmit an order creation request to the securities trading support device (205).

[0095] The securities trading support device (205) can transmit identification information of the first order to the second user's terminal (203) after the first order is created. For example, the securities trading support device (205) can transmit identification information of the first order to the second user's terminal (203) through a message, a push notification of a platform provided by the securities trading support device (205), a link provision, etc. In one embodiment, the securities trading support device (205) can display a securities delivery message in a 1:1 chat room with the first user on the second user's terminal (203).

[0096] Additionally, the securities trading support device (205) may transmit order creation completion information for the first order to the first user's terminal (201) based on the fact that it has transmitted identification information of the first order to the second user's terminal (203). At this time, the order creation completion information may include information indicating that the identification information of the first order has been transmitted to the second user's terminal (203). For example, the information indicating that the identification information of the first order has been transmitted to the second user's terminal (203) may include information that the securities trading support device (205) has completed transmission to the second user's terminal (203), information that the securities trading support device (205) has transmitted to the second user's terminal (203) and received ACK information from the second user's terminal (203), etc. In one embodiment, the securities trading support device (205) may enable the first user's terminal (201) to display a securities delivery message in a 1:1 chat room with the second user.

[0097] Of course, 'Example 2' may also include cases where other users besides the second user are specified. For example, the identification information of the second user and the identification information of the third user are included in the order creation request, and the securities trading support device (205) may transmit the identification information of the first order to the terminals of the second user and the third user based on the identification information of the second user and the identification information of the third user included in the order creation request. That is, depending on the number of user identification information included in the order creation request, the securities trading support device (205) may transmit the identification information of the first order to the terminals of the corresponding users. In addition, the order creation completion information may include information indicating that the identification information of the first order is transmitted to the terminals of the corresponding users.

[0098] Furthermore, it goes without saying that ‘Example 1’ and ‘Example 2’ can be performed in combination. For example, when the first user’s terminal (201) transmits an order creation request to the securities trading support device (205), including the identification information of the second user, the securities trading support device (205) may transmit the identification information of the first order to the second user’s terminal (203) and also to the first user’s terminal (201). In this case, the first user’s terminal (201) may transmit the received identification information of the first order to the second user’s terminal (203), or transmit the identification information of the first order to a third user’s terminal (not shown) that is not the second user.

[0099] In operation 250, the terminal of the second user (203) can obtain identification information of the first order. For example, the terminal of the second user (203) can obtain identification information of the first order from the terminal of the first user (201) in the case of 'Example 1', or obtain identification information of the first order from the securities trading support device (205) in the case of 'Example 2'.

[0100] In operation 260, the second user's terminal (203) may transmit an order inquiry request based on the identification information of the first order to the securities trading support device (205). In one embodiment, the order inquiry request may include a password verification request including a password entered by the second user. The securities trading support device (205) may determine whether the password entered by the second user matches the order verification password of operation 225. If the securities trading support device (205) determines that the password entered by the second user matches the order verification password, it performs operation 270 showing the transaction conditions, and if it determines that it does not match, it may transmit an access refusal message to the second user's terminal (203). The access refusal message may include information that the password is incorrect. It may be desirable to prevent the second user from entering a password when the identification information of the first order is transmitted through the securities sending function in a 1:1 chat room between the first user and the second user.

[0101] Alternatively, in one embodiment, when the second user's terminal (203) transmits an order inquiry request based on the identification information of the first order, the securities trading support device (205) transmits a password input request to the second user's terminal (203), and accordingly, the second user's terminal (203) can transmit a password verification request including a password obtained through user input to the securities trading support device (205). That is, the password verification request may be included in the order inquiry request or may be transmitted separately.

[0102] In operation 270, the securities trading support device (205) may transmit information of the first order to the terminal (203) of the second user. In one embodiment, the securities trading support device (205) may transmit information of the first order to the terminal (203) of the second user based on the fact that the second user is recognized as a legitimate trader. For example, the securities trading support device (205) may transmit information of the first order, including the trading conditions of the first order, to the terminal (203) of the second user based on the fact that the password entered by the second user matches the order confirmation password. In one embodiment, the information of the first order may include an identifier of the first order (e.g., order number), identification information of the first user, trading conditions of the first order, etc., and the trading conditions of the first order may include stock information, quantity information, price information, etc.

[0103] In operation 280, the second user's terminal (203) may transmit a transaction request based on the identification information of the first order to the securities trading support device (205). The transaction request based on the identification information of the first order may be a transaction request based on the information of the first order. The transaction request based on the identification information of the first order may be received from the second user's terminal (203) based on the identification information of the first order being transmitted from the first user's terminal (201) to the second user's terminal (203) ('Example 1'), or it may be received from the second user's terminal (203) based on the identification information of the first order being transmitted from the securities trading support device (205) to the second user's terminal (203) ('Example 2').

[0104] In one embodiment, the transaction request may include acceptance information that the second user accepts the transaction, information regarding the quantity of the transaction request that the second user wishes to trade, price information that the second user wishes to trade, etc.

[0105] In one embodiment, if the second user accepts the transaction conditions of the first order, a transaction request may be transmitted including only simple acceptance information, and if the second user does not accept at least some of the transaction conditions of the first order, a transaction request including a request for consultation may be transmitted. If a request for consultation is transmitted, operation 290 may be performed after all consultations between the transaction parties are completed.

[0106] In one embodiment, when the quantity information of the securities to be traded included in the order creation request includes total quantity information of the securities to be traded and information on the possibility of trading odd shares, the securities trading support device (205) determines whether the quantity of the transaction request is less than or equal to the total quantity identified from the total quantity information of the securities to be traded based on the information on the possibility of trading odd shares, and can perform operation 290 when it is determined that the quantity of the transaction request is less than or equal to the total quantity.

[0107] In one embodiment, when the quantity information of the securities to be traded included in the order creation request includes total quantity information of the securities to be traded and minimum quantity information that can be traded, the securities trading support device (205) determines whether the quantity of the transaction request is greater than or equal to the minimum quantity identified from the minimum quantity information that can be traded and less than or equal to the total quantity identified from the total quantity information of the securities to be traded, and when it is determined that the quantity of the transaction request is greater than or equal to the minimum quantity and less than or equal to the total quantity, it may perform operation 290.

[0108] In operation 290, a securities transaction can be concluded using a counterparty method. In one embodiment, the conclusion of a securities transaction may mean that the securities transaction support device (205) processes the transfer of the securities to be traded from the account of the seller among the first user and the second user to the account of the buyer among the first user and the second user, and processes the transfer of the deposit corresponding to the transaction amount of the securities to be traded from the buyer's account to the seller's account.

[0109] In one embodiment, if the second user accepts the transaction conditions of the first order, the transaction execution procedure may include immediate execution, which performs the transaction execution procedure without a separate confirmation process from the first user regarding the execution of the transaction in accordance with the transaction request. Alternatively, even if the second user accepts the transaction conditions of the first order, the securities trading support device (205) may perform the transaction execution procedure after receiving confirmation from the first user regarding the execution of the transaction in accordance with the transaction request. For example, the securities trading support device (205) may execute the transaction after requesting final confirmation from the first user once more by transmitting information including the trading item, trading quantity, trading price, etc. to the first user's terminal (201) and receiving an acceptance message regarding this from the first user's terminal (201).

[0110] FIG. 3 is a flowchart of a method for generating an order to perform a securities transaction with a specific user according to one embodiment of the present disclosure.

[0111] Each of the operations 210, 220, and 225 of FIG. 3 can correspond to the operations 210, 220, and 225 described above with reference to FIG. 2, and accordingly, the description of the operations 210, 220, and 225 of FIG. 3 will be omitted.

[0112] In operation 310, the securities trading support device (205) may send a balance inquiry request to the securities company server (207) to verify whether the first user possesses securities or deposits for the total quantity included in the order creation request. For example, if the first user is a seller, the securities trading support device (205) must verify that the first user possesses securities for the total quantity desired for sale before creating the order in order to facilitate a secure securities transaction. Additionally, if the first user is a buyer, the securities trading support device (205) must verify that the first user possesses deposits for the total quantity desired for purchase (e.g., the product of the total quantity desired for purchase and the price desired for purchase, and the transaction fees, securities transaction tax, etc.) before creating the order in order to facilitate a secure securities transaction. Accordingly, the securities trading support device (205) may send a balance inquiry request to the securities company server (207) based on the order creation request. In one embodiment, the balance inquiry request may include identification information of the first user, stock information of the securities to be traded, quantity information of the securities to be traded, price information of the securities to be traded, etc.

[0113] In operation 320, the securities company server (207) may transmit a balance inquiry response to the securities trading support device (205) based on a balance inquiry request. In one embodiment, if the first user is a seller, the balance inquiry response may include information regarding whether the first user holds securities for the total quantity desired for sale, information on the quantity of securities held for trading, information on the tradable quantity of securities for trading, etc. Additionally, if the first user is a buyer, the response may include information regarding whether the first user holds deposits for the total quantity desired for purchase, information on available deposits for ordering, etc.

[0114] In one embodiment, in operations 310 and 320, the Application Programming Interface (API) of the securities company server (207) may be used.

[0115] In operation 330, the securities trading support device (205) may generate a temporary order. In one embodiment, the securities trading support device (205) may generate a temporary order if it determines that the first user holds securities or deposits for the total quantity included in the order generation request based on a balance inquiry response. The temporary order may include stock information of the securities to be traded, quantity information of the securities to be traded, price information of the securities to be traded, identification information of the first user, an identifier of the order, etc.

[0116] In one embodiment, in order to create a first order to be actually executed after a temporary order is created, it may be necessary to obtain authorization by acquiring the first user's account password. This will be explained below.

[0117] In operation 340, the securities trading support device (205) can transmit information preparing to enter the account password screen to the first user's terminal (201). For example, the securities trading support device (205) can transmit URL (Uniform Resource Locator) information to the first user's terminal (201) to prepare to enter the account password screen.

[0118] In operation 342, the first user's terminal (201) can transmit a request to the securities trading support device (205) to prepare for entry into the account password screen based on information preparing for entry into the account password screen.

[0119] In operation 344, the securities trading support device (205) may transmit a web access token request to the securities company server (207) based on a request to prepare to enter the account password screen received from the first user's terminal (201). In one embodiment, the access token may be a token that the server verifies whether it corresponds to an authenticated user. That is, the securities trading support device (205) may transmit a web access token request to allow the securities company server (207) to verify whether the securities trading support device (205) or the first user's terminal (201) corresponds to an authenticated user in order to use the web provided by the securities company server (207).

[0120] In operation 346, if the securities company server (207) determines that the securities trading support device (205) or the terminal (201) of the first user corresponds to an authenticated user, it may send a web access token response to the securities trading support device (205).

[0121] In operation 348, the securities trading support device (205) may transmit a response to the first user terminal (201) to prepare for entry into the account password screen based on the web access token response. The response to prepare for entry into the account password screen may include information of the securities company server (207) so that the first user terminal (201) transmits a request for an account number password screen to the securities company server (207) in operation 350.

[0122] In operation 350, the first user's terminal (201) transmits an account password screen request to the securities company server (207) based on a response preparing to enter the account password screen, and in operation 360, the securities company server (207) may provide the account password screen to the first user's terminal (201). The first user's terminal (201) may obtain user input for entering an account password to access the account by displaying the account password screen. Accordingly, in operation 370, the first user's terminal (201) may transmit a request to the securities company server (207) to submit the account password obtained according to the user input.

[0123] Based on the fact that the account password transmitted in operation 370 matches the pre-set account password of the first user, the securities company server (207) can transmit an order token and an order token delivery link to transmit the order token to the first user's terminal (201) in operation 380 and to the securities trading support device (205).

[0124] In operation 390, the first user's terminal (201) can transmit an order token submission request to the securities trading support device (205) based on the order token delivery link received from the securities company server (207).

[0125] In operation 230, the securities trading support device (205) may generate a first order and identification information of the first order based on an order token submission request received from the terminal (201) of the first user. However, the generated first order may not be displayed on the quote board. In one embodiment, the identification information of the first order may include a link, a deep link, an app link, a deferred deep link, etc. Operation 230 of FIG. 3 may correspond to operation 230 described above with reference to FIG. 2.

[0126] In operation 240, the securities trading support device (205) may transmit order creation completion information (240) based on the identification information of the first order. Likewise, operation 240 of FIG. 3 may correspond to operation 240 described above with reference to FIG. 2.

[0127] FIG. 4 is a flowchart of a method for concluding a transaction by a specific user according to one embodiment of the present disclosure.

[0128] Referring to FIG. 4, in operation 250, the terminal (203) of the second user can obtain identification information of the first order. In one embodiment, the terminal (203) of the second user can obtain identification information of the first order for concluding a transaction of the first order with the first user from at least one of a securities trading support device (205) or the terminal (201) of the first user. Operation 250 of FIG. 4 may correspond to operation 250 described above with reference to FIG. 2.

[0129] In operation 260, the terminal (203) of the second user may transmit an order inquiry request to the securities trading support device (205) based on the identification information of the first order. Operation 260 of FIG. 4 may correspond to operation 260 described above with reference to FIG. 2.

[0130] In operation 410, the securities trading support device (205) may transmit an order inquiry response to the second user's terminal (203) based on an order inquiry request. In one embodiment, the order inquiry response may include information that the second user requires an order confirmation password to verify order information. Furthermore, the securities trading support device (205) may provide an interface to the second user's terminal (203) for entering the order confirmation password.

[0131] In operation 420, the second user's terminal (203) can transmit a password verification request including the password entered by the second user to the securities trading support device (205).

[0132] In operation 425, the securities trading support device (205) can determine whether the password entered by the second user included in the password verification request matches the order verification password set by the first user. If the password entered by the second user included in the password verification request matches the order verification password set by the first user, operation 270 is performed, and if it does not match, the securities trading support device (205) can transmit information to the second user's terminal (203) that the order cannot be verified because the password does not match.

[0133] In operation 270, the securities trading support device (205) can transmit information of the first order to the terminal (203) of the second user. That is, the terminal (203) of the second user can obtain information of the first order as the password entered by the second user matches the order confirmation password set by the first user. In one embodiment, the information of the first order may include the identifier of the first user, the trading conditions of the first order, etc. The trading conditions of the first order may include information on the stock of the securities to be traded, quantity information of the securities to be traded, price information of the securities to be traded, etc.

[0134] In operation 430, the terminal (203) of the second user may obtain user input for securities trading based on the information of the first order. In one embodiment, the terminal (203) of the second user may display the trading conditions of the first order and obtain user input regarding the second user’s expression of intent to accept the transaction, the second user’s expression of intent to modify at least part of the trading conditions, or the second user’s expression of intent to refuse the transaction. When user input regarding the expression of intent to accept is obtained, operation 280 may be performed; when user input regarding the expression of intent to condition is obtained, a consultation interface may be provided; and when user input regarding the expression of intent to refuse is obtained, the expression of intent to refuse may be transmitted to the terminal (201) of the first user through the securities trading support device (205).

[0135] In operation 280, the terminal (203) of the second user may transmit a transaction request based on the identification information of the first order to the securities transaction support device (205). In one embodiment, the transaction request may include only an intention to accept, or may include information regarding the type of securities to be traded, the transaction quantity, the transaction price, etc., along with the intention to accept. Operation 280 of FIG. 4 may correspond to the operation 280 described above with reference to FIG. 2.

[0136] In operation 440, the securities trading support device (205) may transmit a balance inquiry request to the securities company server (207). In one embodiment, the securities trading support device (205) may identify trading conditions including at least one of the type of securities to be traded, the trading quantity, and the trading price based on the trading request, and transmit a balance inquiry request to check whether there are securities or deposits corresponding to the second user's account based on the trading conditions. Accordingly, the balance inquiry request may include the second user's identification information, information on the type of securities to be traded, the trading quantity, the trading price, etc.

[0137] For example, if the second user is a seller, the securities trading support device (205) can transmit a balance inquiry request regarding whether the second user holds securities of the corresponding stock in the second user's account in an amount equal to the trading quantity, and if the second user is a buyer, it can transmit a balance inquiry request regarding whether the second user holds a deposit for the trading quantity in the second user's account.

[0138] In operation 445, the securities company server (207) may transmit a balance inquiry response to the securities trading support device (205). In one embodiment, if the second user is a seller, the balance inquiry response may include information regarding whether the second user holds securities for the trading quantity, information on the quantity of securities held for trading, information on the tradable quantity of securities for trading, etc. Additionally, if the second user is a buyer, the response may include information regarding whether the second user holds deposits for the trading quantity, total deposit information, orderable deposit information, etc.

[0139] In operation 450, the securities trading support device (205) may create a temporary transaction when there is a tradable amount of securities or deposits in the second user's account. The temporary transaction may include information on the type of securities to be traded, information on the trading quantity, information on the trading price, identification information of the first user, identification information of the second user, identification information of the order, etc.

[0140] In one embodiment, in order to actually execute a transaction after a temporary transaction has been created, it may be necessary to obtain the account password of the second user to acquire transfer authority. This will be explained below.

[0141] In operation 460, the securities trading support device (205) can transmit information preparing to enter the account password screen to the second user's terminal (403). For example, the securities trading support device (205) can transmit URL (Uniform Resource Locator) information to the second user's terminal (203) to prepare to enter the account password screen.

[0142] In operation 462, the second user's terminal (403) can transmit a request to the securities trading support device (205) to prepare for entry into the account password screen based on information preparing for entry into the account password screen.

[0143] In operation 464, the securities trading support device (205) may transmit a web access token request to the securities company server (207) based on a request to prepare to enter the account password screen received from the second user's terminal (203). In one embodiment, the securities trading support device (205) may transmit a web access token request to allow the securities company server (207) to verify whether the securities trading support device (205) or the second user's terminal (203) corresponds to an authenticated user in order to use the web provided by the securities company server (207).

[0144] In operation 466, if the securities company server (207) determines that the securities trading support device (205) or the terminal (203) of the second user corresponds to an authenticated user, it may send a web access token response to the securities trading support device (205).

[0145] In operation 468, the securities trading support device (205) may transmit a response to the second user terminal (203) to prepare for entry into the account password screen based on the web access token response. The response to prepare for entry into the account password screen may include information of the securities company server (207), for example, identification information of the securities company server (207), in order for the second user terminal (203) to transmit an account number password screen request to the securities company server (207) in operation 470.

[0146] In operation 470, the second user's terminal (203) transmits an account password screen request to the securities company server (207) based on a response ready to enter the account password screen, and in operation 472, the securities company server (207) may provide the account password screen to the second user's terminal (203). The second user's terminal (203) may display the account password screen to obtain user input for the second user to enter the account password to access the account. Accordingly, in operation 474, the second user's terminal (203) may transmit a request to the securities company server (207) to submit the account password obtained according to the user input.

[0147] In operation 480, the securities company server (207) can transmit an order token and an order token delivery link to the second user's terminal (203) based on the fact that the account password transmitted in operation 474 matches the account password of the second user that was pre-set.

[0148] In operation 490, the second user's terminal (203) can transmit an order token submission request to the securities trading support device (205) based on the order token delivery link received from the securities company server (207).

[0149] In operation 290, a securities transaction using a counterparty method may be executed based on a request to submit an order token. In one embodiment, the execution of a securities transaction may include the securities transaction support device (205) processing the transfer of the securities to be traded from the account of the seller among the first user and the second user to the account of the buyer among the first user and the second user, and processing the transfer of a deposit corresponding to the transaction amount of the securities to be traded from the buyer's account to the seller's account. Operation 290 will be described in more detail later with reference to FIG. 5.

[0150] FIG. 5 is a flowchart of a method for concluding a securities transaction using a counterparty trading method according to one embodiment of the present disclosure.

[0151] Referring to FIG. 5, specific operations of operation 290 are illustrated. In operation 510, the securities trading support device (205) generates a finally confirmed transaction, and based on the generated transaction, in operation 520, it may transmit a transaction execution request to the securities company server (207). The transaction execution request may include identification information of the buyer, identification information of the seller, identification information of the first order, stock information, execution price, execution quantity, etc.

[0152] In operation 530, the securities company server (207) can transfer the securities to be traded from the seller's account among the first user and the second user to the buyer's account among the first user and the second user, and after transferring the deposit amount corresponding to the transaction price of the securities to be traded from the buyer's account to the seller's account, transmit a transaction execution response to the securities trading support device (205) indicating that the transaction has been executed.

[0153] In operation 540, the securities trading support device (205) may change the transaction status based on the transaction execution response. For example, as the transaction of the first order is completed, the securities trading support device (205) may delete the first order, mark it as a completed order, process the first order so that it is not exposed to the trading parties, or modify the transaction conditions of the first order. For example, if the transaction is executed for only a portion of the quantity less than the total quantity of the first order, the securities trading support device (205) may update the total quantity of the first order to a quantity obtained by subtracting the executed quantity from the existing total quantity.

[0154] Furthermore, the market price information for the securities subject to trading can be determined on the platform provided by the securities trading support device (205) and provided through the platform.

[0155] In one embodiment, the securities trading support device (205) may update the number of inquirers for the first order based on the identification information of the second user.

[0156] In operation 550, the securities trading support device (205) can transmit transaction completion information to the first user's terminal (201) and the second user's terminal (203).

[0157] FIG. 6 is a drawing showing a case where the number of inquirers of an order is adjusted according to one embodiment of the present disclosure.

[0158] Referring to FIG. 6, a first user may want to share identification information of a first order and perform a transaction in a chat interface with a second user. However, the number of viewers who can view the transaction conditions of an order created for a single security of a user may be controlled so as not to exceed a predetermined value (e.g., 100 people). For example, the number of viewers for the transaction conditions of an order for a security subject to trading by the first user may be controlled so as not to exceed a predetermined value. Therefore, when the number of viewers reaches a predetermined value, the securities trading support device may control the transaction so that the first user can no longer view the transaction conditions for the order for the corresponding security.

[0159] In the present disclosure, an order to which a viewer limit setting is applied refers to an order generated based on a trading method involving a specific user, and does not include orders displayed on a quote board. Therefore, orders displayed on a quote board can be viewed by various users without any limit on the number of viewers. Additionally, an order to which a viewer limit setting is applied may include multiple orders generated by the user regarding the relevant security. For example, the sum of the number of viewers for the trading conditions of multiple orders for a security subject to trading, generated by a first user, may be adjusted so as not to exceed a predetermined value. That is, when the same user generates multiple orders for the same security, the sum of the number of viewers for the trading conditions of multiple orders for a single security may be adjusted so as not to exceed a predetermined value.

[0160] In one embodiment, for an order created by a user for one of the securities subject to trading, the number of viewers who can view the trading conditions during a predetermined period (e.g., one year) may be controlled so as not to exceed a predetermined value. For example, the number of viewers within a predetermined period of the trading conditions of an order for a first user's securities subject to trading may be controlled so as not to exceed a predetermined value.

[0161] In one embodiment, the securities trading support device (205) may count the number of inquirers regarding the trading conditions of an order for a security subject to trading by a user (e.g., the first user) in order to set a limit on the number of inquirers. At this time, users belonging to a pre-designated group among the inquirers may be excluded when counting the number of inquirers. The pre-designated group may include shareholders, professional investors, etc. who already hold the relevant security. To this end, the securities trading support device (205) may perform at least one of the following embodiments. For convenience, the following description uses the case where the first user creates an order and the second user inquires about it as an example; however, it is understood that this can be applied in the same way when users other than the first user create an order or when users other than the second user inquire about an order.

[0162] Example 3-1

[0163] Each order for a stock subject to trading by the first user can be configured so that it can be viewed by only one user. For example, if one user views it, subsequent viewing by other users may be blocked, a message indicating that viewing is not possible may be sent in response to receiving a viewing request from another user, or the order may be deleted. In this case, when an order is configured so that it can be viewed by only one user, the securities trading support device (205) may limit the number of viewers by counting the number of times an order for the corresponding stock is created by that one user.

[0164] In one embodiment, the securities trading support device (205) may determine whether the number of orders created by the first user for the corresponding stock during the period is less than a predetermined value based on an order creation request received from the first user. Here, the period may be a predetermined period, or if there is no predetermined period, it may mean any period.

[0165] In one embodiment, if the securities trading support device (205) determines that the number of times the first user creates an order for the corresponding stock during the period is less than a predetermined value, it may create an order for the first user's corresponding stock (e.g., the first order). Conversely, if the securities trading support device (205) determines that the number of times the first user creates an order for the corresponding stock during the period is greater than or equal to a predetermined value, it may send an order creation impossibility message to the first user's terminal (201).

[0166] Example 3-2

[0167] The securities trading support device (205) can limit the number of inquirers by counting the number of inquirers for orders for a single stock generated by one user. In one embodiment, the securities trading support device (205) receives an order inquiry request for a first order from a terminal of a second user and, based on the order inquiry request, can determine whether the number of inquirers for orders for a stock subject to trading by the first user during the relevant period is less than the aforementioned predetermined value. At this time, the order inquiry request may include a password verification request. For example, the securities trading support device (205) can determine whether the number of inquirers is less than the aforementioned predetermined value when the second user makes an order inquiry request based on the identification information of the first order to verify the trading conditions of the first order, or when the password entered by the second user matches the order verification password set by the first user. That is, when the securities trading support device (205) performs the aforementioned operation 260 with reference to FIG. 2 or performs the aforementioned operation 420 with reference to FIG. 4, it can determine whether the number of inquirers for orders regarding the first user’s trading target securities during the corresponding period is less than the aforementioned predetermined value. Here, the corresponding period may be a predetermined period, or if there is no predetermined period, it may mean any period.

[0168] In one embodiment, if the number of inquirers for an order regarding a security item subject to trading by the first user exceeds a predetermined value, the securities trading support device (205) may transmit a message indicating that inquiry is not possible to the second user's terminal (203). Furthermore, the securities trading support device (205) may also transmit information to the first user's terminal (201) that the number of inquirers for the first order has been exceeded.

[0169] In one embodiment, if the number of inquirers for an order for a security subject to trading by the first user is less than a predetermined value, the securities trading support device (205) may transmit information of the first order, including the trading conditions of the first order, to the terminal (203) of the second user. The information of the first order, including the trading conditions, may be transmitted by being included in a password confirmation response.

[0170] Example 3-3

[0171] Each order for a security subject to trading by the first user can be configured so that it can be viewed by only one user.

[0172] In this embodiment, the securities trading support device (205) calculates the number of times an order can be created for a stock subject to trading by the first user, and can create a first order based on an order creation request only when the number of times an order can be created is 1 or more. Additionally, the securities trading support device (205) can transmit information on the number of times an order can be created for the corresponding stock to the terminal (201) of the first user.

[0173] A method for calculating the number of times an order can be generated may include an action of setting an initial value of the number of times an order can be generated to a predetermined value (e.g., 100), an action of decreasing the number of times an order can be generated by 1 when the first user generates an order for the item of the securities subject to trading, and an action of increasing the number of times an order can be generated by 1 when a reason for exclusion from counting occurs.

[0174] In another equivalent embodiment, the securities trading support device (205) calculates the number of order inquirers for an order for a security item subject to trading by the first user, and if the number of inquirers is less than the maximum number of inquirers, it can generate the first order based on an order creation request. Additionally, the securities trading support device (205) can transmit information on the current number of inquirers for an order for the security item to the terminal (201) of the first user.

[0175] A method for calculating the number of order lookup users may include an action of setting the initial value of the number of order lookup users to a predetermined value (e.g., 0), an action of increasing the number of order lookup users by 1 when the first user creates an order for a security subject to trading, and an action of decreasing the number of order lookup users by 1 when a reason for exclusion from counting occurs.

[0176] The above reasons for exclusion from counting may include at least one of the following: when an order for a security subject to trading by the first user is closed without inquiry; when a user who newly inquires about an order for a security subject to trading by the first user is a user who has already been counted; when a predetermined period has elapsed since a counted order was inquired; or when a user who newly inquires about an order for a security subject to trading by the first user is a user belonging to a predetermined group. Cases where an order is closed without inquiry may include cases where the validity period expired prior to inquiry or where the first user closed the order prior to inquiry.

[0177] In one embodiment, an already counted viewer may refer to a user who has previously viewed an order for a stock of the first user's trading securities. Alternatively, the already counted viewer may refer to a user who has viewed an order for a stock of the first user's trading securities within a recent predetermined period. Alternatively, the already counted viewer may refer to a user who has previously viewed an order for a stock of the first user's trading securities without belonging to a predetermined group. Alternatively, the already counted viewer may refer to a user who has viewed an order for a stock of the first user's trading securities within a recent predetermined period without belonging to a predetermined group.

[0178] In one embodiment, the counted order may refer to an order among the generated orders that does not fall under the reason for exclusion from counting.

[0179] Of course, the above Examples 3-1 to 3-3 may be implemented in combination.

[0180] The methods described above can be considered substantially identical or at least equivalent to the methods that result in the same outcome. For example, the method of storing the number of possible order creations and increasing or decreasing it by 1 whenever an event occurs, and the method of calculating the current number of possible order creations based on previously recorded event data whenever the number of possible order creations is needed, can be considered substantially identical to each other.

[0181] FIGS. 7 and 8 describe a method for executing a transaction by creating a first order when the first user is the seller and the second user is the buyer. However, this is merely an example, and it goes without saying that a similar method can be performed even when the first user is the buyer and the second user is the seller.

[0182] FIG. 7 is a diagram illustrating a method for a seller to generate an order to enter into a transaction with a specific buyer according to one embodiment of the present disclosure.

[0183] Referring to FIG. 7, the terminal of the first user may communicate with a securities trading support device to receive a form (710) for generating sell order generation request information. The terminal of the first user may receive user input for the form (710) for generating sell order generation request information. The terminal of the first user may receive user input for at least one of stock information (e.g., stock name, stock code, etc.), desired selling price (721), desired minimum quantity information (727), desired total quantity information (725), information on the seller's intention to execute immediately (729), information on the period during which the sell order is valid, information on whether price negotiation is possible (723), or trading method information. For example, the desired minimum quantity information (727) may be obtained through an interface for entering the desired minimum quantity or through an interface for selecting whether to trade single shares. However, this is merely an example, and the desired minimum quantity information (727) may be obtained through various interfaces.

[0184] In one embodiment, the terminal of the first user may transmit a request to a securities trading support device to generate an order to trade securities with a specific user based on obtaining user input regarding trading method information including a trading method (730) that is a trading method with a specific user. The request to generate an order may include at least one of a stock name, a desired selling price, information on the minimum desired selling quantity, the total desired selling quantity, information on the first user's intention to execute immediately, a period during which the sell order is valid, trading method information including a trading method that is a trading method with a specific user and a trading method that is a safe trading method, whether price negotiation is possible, the account number of the user's account, or a total amount.

[0185] In one embodiment, the immediate execution intent information may include a period during which the first user's intent that a trading contract can be executed without a separate confirmation process upon meeting certain requirements is valid (hereinafter referred to as the "immediate execution possible period"). For example, when the first user clicks a user interface corresponding to the immediate execution intent information, the first user's terminal may display an interface for selecting the immediate execution possible period. When the first user's terminal receives information regarding the period from user input based on the interface for selecting the immediate execution possible period, the first user's terminal may transmit sell order creation request information including information regarding the period to a securities trading support device.

[0186] For example, the terminal of the first user may transmit an order creation request to a securities trading support device that includes information such as <Stock information: Eight Percent A12345, Desired selling price: 84,000 won, Desired total quantity: 5, Desired minimum quantity information: Odds trading possible, Immediate execution period: 5 days, Sell order validity period: 90 days, Price negotiation possible: Not possible>.

[0187] In one embodiment, the securities trading support device may determine whether the legitimacy of an order creation request is recognized. Cases where the legitimacy of the order creation request is recognized may include cases where the first user holds more than the total quantity of securities of the relevant stock that they wish to sell. For example, if the securities trading support device determines that the first user holds more than the total quantity of securities corresponding to the stock information that they wish to sell, the securities trading support device determines that the legitimacy of the order creation request is recognized and may provide an interface (740) for setting an order confirmation password to the first user's terminal. The first user's terminal may obtain user input regarding the order confirmation password based on the interface (740) for setting the order confirmation password and transmit information for setting the order confirmation password to the securities trading support device.

[0188] In one embodiment, the securities trading support device may generate a first order and identification information (760) of the first order corresponding to an order creation request. Additionally, the securities trading support device may transmit order creation completion information based on the identification information (760) of the first order to the terminal of the first user. The order creation completion information may include the identification information (760) of the first order, and the terminal of the first user may transmit the identification information (760) of the first order to the terminal of the second user through a chat interface such as FIG. 6.

[0189] FIG. 8 is a drawing illustrating a method for a specific buyer to enter into a transaction according to one embodiment of the present disclosure.

[0190] Referring to FIG. 8, the terminal of the second user obtains identification information of the first order to enter into a transaction of the first order with the first user, and based on the identification information of the first order, can transmit an order inquiry request for the first order to a securities trading support device.

[0191] In one embodiment, identification information of the first order may be provided to the second user's terminal through at least one of transmission from the first user's terminal to the second user's terminal or notification information provided to the second user's terminal by a securities trading support device.

[0192] In one embodiment, the securities trading support device may transmit an order inquiry response to a second user's terminal. The order inquiry response may include an interface (830) instructing the user to enter an order confirmation password. Based on the interface (830) instructing the user to enter an order confirmation password, the second user's terminal may obtain the password entered by the second user and transmit a password confirmation request including the password entered by the second user to the securities trading support device. The securities trading support device may determine whether the password entered by the second user matches the order confirmation password set by the first user, and if they match, transmit information on the first order (810) including the trading conditions of the first order to the second user's terminal. In one embodiment, the information on the first order (810) may include information on the stock of the securities to be traded, price information, estimated market capitalization, quantity information of the securities to be traded (e.g., information on the total quantity available for trade, information on whether split execution is possible for the total quantity, information on the minimum quantity available for trade, information on whether odd share trading is possible, etc.), whether price negotiation is possible, trading method information, etc.

[0193] In one embodiment, a securities trading support device may receive a transaction request for a first order from a second user's terminal based on information of a first order. In one embodiment, the transaction request may include price information, purchase quantity information, etc. For example, as shown in FIG. 8, if the information of the first order (810) includes information that price negotiation is impossible and information that the minimum tradable quantity is 1 share, the transaction request for the first order may include the identifier of the first order (e.g., order number) and transaction quantity information, and the price information may be omitted.

[0194] For example, if the information of the first order includes information regarding the possibility of single-share trading, the securities trading support device determines whether the purchase quantity is less than or equal to the total tradable quantity, and if the purchase quantity exceeds the total tradable quantity, it may transmit a message indicating that trading is impossible to the second user's terminal. Alternatively, if the second user inputs a purchase quantity exceeding the total tradable quantity at the second user's terminal, the device may output a message indicating that trading is impossible, thereby allowing the user to adjust the purchase quantity.

[0195] As another example, if the information of the first order includes information on the minimum tradable quantity, the securities trading support device may determine whether the purchase quantity is greater than or equal to the minimum quantity identified from the information on the minimum tradable quantity and less than or equal to the total tradable quantity. If the purchase quantity is less than the minimum quantity or exceeds the total quantity, the securities trading support device may transmit a message indicating that trading is impossible to the second user's terminal. Alternatively, if the second user inputs a purchase quantity less than the minimum quantity or a purchase quantity exceeding the total tradable quantity at the second user's terminal, the device may output a message indicating that trading is impossible, thereby causing the user to adjust the purchase quantity. As a result of adjusting the purchase quantity, the transaction request for the first order may include information on a purchase quantity that is greater than or equal to the minimum tradable quantity and less than or equal to the total tradable quantity.

[0196] In one embodiment, the securities trading support device may, based on a transaction request for a first order, investigate whether the second user has available funds for the order quantity. If the second user possesses the said funds, the securities trading support device may execute the transaction by providing the second user's terminal with an interface (840) for entering an account password. Regarding the execution of the transaction in accordance with the second user's transaction request, the securities trading support device may execute the transaction execution process without obtaining separate confirmation from the first user, based on the fact that the user's immediate execution intent information (729) is included in the order creation request received from the first user's terminal. However, if the user's immediate execution intent information (729) is not included in the order creation request received from the first user's terminal, or if a request to change order information, such as a price change, is received from the second user's terminal, the securities trading support device may execute the transaction execution procedure after obtaining confirmation from the first user regarding the execution of the transaction in accordance with the second user's transaction request.

[0197] FIG. 9 is a block diagram of a securities trading support device for a counterparty trading method according to one embodiment of the present disclosure.

[0198] Referring to FIG. 9, a securities trading support device for a direct trading method may include a transceiver (910), a memory (920), and a processor (930). However, not all components shown in FIG. 9 are essential components of the securities trading support device for a direct trading method. The securities trading support device for a direct trading method may be implemented with more components than those shown in FIG. 9, or with fewer components than those shown in FIG. 9. Furthermore, the transceiver (910), the processor (930), and the memory (920) may be implemented in the form of a single chip.

[0199] In one embodiment, the transceiver (910) may communicate with a terminal or other electronic device connected via wired or wireless connection to a securities trading support device for a counterparty trading method. For example, the transceiver (910) may receive order creation request information from a first user's terminal, including information on the first user's intention to execute immediately, the name of the security, the desired trading price of the security, the desired total quantity of the security, and information on the desired minimum quantity of the security. Additionally, the transceiver (910) may receive securities trading request information from a second user's terminal, including a purchase quantity that is greater than or equal to the desired minimum quantity identified from the desired minimum quantity information and less than or equal to the desired total quantity.

[0200] Various types of data, such as programs and files, such as applications, can be installed and stored in the memory (920). The processor (930) may access and use the data stored in the memory (920), or may store new data in the memory (920). In one embodiment, the memory (920) may include a database.

[0201] The processor (930) controls the overall operation of the securities trading support device for the over-the-counter method and may include at least one processor such as a CPU, GPU, etc. The processor (930) may control other components included in the securities trading support device for the over-the-counter method to perform operations for operating the securities trading support device for the over-the-counter method. For example, the processor (930) may execute a program stored in memory (920), read a stored file, or save a new file. In one embodiment, the processor (930) may perform operations for operating the securities trading support device for the over-the-counter method by executing a program stored in memory (920). For example, the processor (930) may receive a request to create an order to trade securities with a specific user from the terminal of the first user, create a first order and identification information of the first order corresponding to the request to create an order, transmit order creation completion information based on the identification information of the first order to the terminal of the first user, receive a transaction request based on the identification information of the first order from the terminal of the second user, process the transfer of the securities to be traded from the account of the seller among the first user and the second user to the account of the buyer among the first user and the second user based on the transaction request, and perform a transaction execution procedure in which a deposit corresponding to the transaction amount of the securities to be traded is transferred from the account of the buyer to the account of the seller.

[0202] In one embodiment, the processor (930) may generate a first order and identification information for the first order, and then determine whether there are securities or deposits corresponding to quantity information included in the order creation request in the first user's account when a predetermined event occurs (e.g., periodically).
