Description

Device for stock trading using buy and sell lines on stock price charts and method therefor

[0001] The present invention relates to a technology for supporting stock trading, and more specifically, to a device for stock trading using a buy line and a sell line on a stock price chart, and a method therefor.

[0002] Recently, with the increasing number of individual investors, interest in investment products, including stocks and cryptocurrencies, has grown. To trade, individual investors must use at least one of the following: a securities firm, a cryptocurrency exchange website, a home trading system (HTS), or an online trading system (MTS).

[0003] While the number of individual investors has increased, unlike professional investors, individual investors are unable to monitor the daily fluctuations of investment products due to the need to focus on their main business. This often leads to them missing out on potential unrealized profits and losses. Consequently, individual investors utilize websites, HTSs, and MTSs to place fractional orders using price-based limit orders. However, using limit orders requires the manual entry of price and quantity.

[0004] Furthermore, as individual investors' portfolios expand, the difficulty arises of accurately identifying target buy and sell prices for each individual asset. This can lead to missed investment opportunities, potentially leading to missed profits or increased losses.

[0024] According to the present invention, not only is user convenience improved because the user can easily and conveniently designate buy and sell prices through an input means that can be visually confirmed on a stock price chart, but in particular, when a user wishes to make a split transaction by designating a buy or sell price range, the user can quickly designate two specific ranges while viewing the price flow at a glance on the chart, and automatically distribute multiple buy or sell prices and quantities to support split transactions.

[0025] According to the present invention, when the price of an investment product is highly volatile, split buy / sell operations utilizing two lines on a chart enable rapid split buy / sell operations, thereby preventing unrealized profits and losses. Furthermore, split buy / sell operations utilizing two lines on a chart simplify the split buy / sell technique for a single investment product, facilitating the handling of multiple investment products. Furthermore, for single buy / sell orders with a single line, short-term traders are provided with a means to quickly execute buy / sell orders, thereby providing an opportunity to increase returns.

[0044] Referring to FIGS. 1 and 2, a database (DB) according to an embodiment of the present invention is constructed in a storage unit (SM), and an interface unit (100), a purchase processing unit (200), and a sale processing unit (300) according to an embodiment of the present invention can access this database (DB) to store or reference data. In this case, although the data is described as being stored in the storage unit (SM) as an example, it is a well-known fact that it is also possible to store part or all of the data by linking with an external server or database as needed and access and use it when needed.

[0045] The specific operations of the interface unit (100), purchase processing unit (200), and sale processing unit (300) described above and the data stored in the database (DB) will be described in more detail below.

[0046] Next, a method for stock trading using buy and sell lines on a stock price chart according to an embodiment of the present invention will be described. First, a method for stock purchase using buy lines on a stock price chart according to an embodiment of the present invention will be described. Figure 3 is a flowchart illustrating a method for stock purchase using buy lines on a stock price chart according to an embodiment of the present invention. Figures 4 to 7 are screen examples illustrating a method for stock trading using buy and sell lines on a stock price chart according to an embodiment of the present invention.

[0047] Referring to FIG. 3, when a user selects one of multiple stocks, the interface unit (100) provides a stock trading interface (STIF) corresponding to the stock selected by the user in step S110. This stock trading interface (STIF) is illustrated in FIG. 4.

[0048] As shown in Figure 4, the stock trading interface (STIF) includes a stock price chart (CT), multiple menu buttons (BT), an order window (OW), and a ruler (SC).

[0049] A stock chart (CT) visually represents the price movements in the stock market of a stock selected by the user.

[0050] The multiple menu buttons (BT: B1 to B6) include auto buy (B1), auto buy cancel (B2), auto sell (B3), auto sell cancel (B4), auto buy sell correction (B5), and auto buy sell confirmation (B6), and are intended to provide the function of the menu corresponding to each menu button.

[0051] The order window (OW) includes a plurality of buttons (O1 to O4) and a plurality of dialog boxes (O5 to O7). The plurality of buttons (O1 to O4) include a sell button (O1) for selecting a sell function, a buy button (O2) for selecting a buy function, an order button (O3) for executing an order, and a reset button (O4) for performing an initialization. The plurality of dialog boxes (O5 to O7) include a highest price dialog box (O5) for entering a highest price, a lowest price dialog box (O6) for entering a lowest price, and an order quantity dialog box (O7) for entering an order quantity to be bought or sold.

[0052] The ruler (SC) is one of the price input tools for buying or selling. The ruler (SC) can be synchronized with the stock price chart and its price axis to select a price. To this end, the ruler (SC) includes a scale (C1) corresponding to the stock price and a controller (C2) that moves along the scale (C1). Referring to Figure 5, the user can select prices (R1, R2, R3, R4) on the scale (C1) by moving the controller (C2) on the scale (C1). For example, moving the triangle- or arrow-shaped controller (C2) with the mouse will display corresponding horizontal price lines (RL1, RL2, RL3, RL4) on the stock price chart (CT), and clicking the mouse at a desired price will input that price.

[0053] Additionally, the stock trading interface (STIF) may provide additional drawing tools and reference tools. The drawing tool draws horizontal price lines (L1, L2, L3, L4) corresponding to prices on the stock chart (CT) based on user manipulation, and inputs prices corresponding to the horizontal price lines (L1, L2, L3, L4). As illustrated in Figure 6, the reference tool draws a crosshair (CR1) on the stock chart (CT) based on the cursor position corresponding to the user manipulation, allowing for accurate confirmation of the stock price (CR2).

[0054] The stock trading interface (STIF) further includes a buy pop-up window (PPW) and a sell pop-up window (SPW), as illustrated in Figure 7. The buy pop-up window (PPW) and sell pop-up window (SPW) pop up when a specific event occurs.

[0055] The purchase pop-up window (PPW) includes a dialog box (P1, P2) that displays the stock code number and stock name to be purchased, a dialog box (P3, P4) that displays or allows input of the highest and lowest purchase prices, and a dialog box (P5) that allows input of the order quantity for the stock to be purchased, i.e. the purchase quantity.

[0056] The sell pop-up window (SPW) includes a dialog box (S1, S2) that displays the stock code number and stock name, a dialog box (S3, S4) that displays or allows you to enter the highest and lowest sell prices, and a dialog box (S5) that allows you to enter the order quantity for the stock you wish to sell, i.e. the sell quantity.

[0057] The background color of the stock trading interface (STIF) is white, and when the automatic purchase button (B1) or the purchase button (O2) is selected on the stock trading interface (STIF), the interface unit (100) can change the purchase button of the stock trading interface (STIF) to blue. In addition, when the automatic sell button (B3) or the sell button (O1) is selected on the stock trading interface (STIF), the interface unit (100) can change the sell button of the stock trading interface (STIF) to red. In addition, when the initialization button (O4) is selected, the interface unit (100) can change the color of the button to white.

[0058] The interface unit (100) can receive input of a purchase quantity corresponding to a stock type and one purchase price or two different purchase prices according to the user's operation on the stock trading interface (STIF) at step S120.

[0059] According to one embodiment of step S120, the interface unit (100) can receive input of the purchase quantity and purchase price through input using the user's drawing tool, reference tool, and purchase pop-up window. Specifically, the following is provided.

[0060] The interface unit (100) may provide a drawing tool when the user selects the automatic purchase button (B1). When one horizontal price line is drawn on a stock price chart (CT) through the drawing tool according to the user's operation, the interface unit (100) may receive one purchase price corresponding to the drawn horizontal price line, and when two different horizontal price lines (e.g., L1, L2) are drawn, the interface unit (100) may receive two different purchase prices corresponding to the two different horizontal price lines. Before inputting the purchase price through the drawing tool, the user may use the crosshair of the reference tool to confirm the exact price. As described above, when one or two purchase prices are entered, the interface unit (100) pops up a purchase pop-up window (PPW) including a dialog box (P5) for entering the purchase quantity, and receives the purchase quantity through the dialog box (P5) for entering the purchase quantity according to the user's input.

[0061] According to another embodiment of step S120, the interface unit (100) can receive purchase quantity and purchase price input through a price chart and a price selector (C2) and a purchase pop-up window (PPW) that can be synchronized with the price axis of the stock chart. Specifically, the following is provided.

[0062] The interface unit (100) can activate the ruler (SC) when the user selects the automatic purchase button (B1). When one price is selected through the ruler (SC), the interface unit (100) can display one horizontal price line corresponding to the selected price and receive one purchase price corresponding to the displayed horizontal price line. Alternatively, when two different prices (e.g., R1, R2) are selected through the ruler, the interface unit (100) can display two different horizontal price lines (e.g., RL1, RL2) corresponding to the two different selected prices and receive two different purchase prices corresponding to the two different displayed horizontal price lines. In this way, when one or two purchase prices are entered through the ruler (SC), the interface unit (100) pops up a purchase pop-up window (PPW) that includes a dialog box (P5) for entering the purchase quantity, and according to the user's input, the purchase quantity can be entered through the dialog box (P5) for entering the purchase quantity.

[0063] According to another embodiment of step S120, the interface unit (100) can receive a purchase price through a dialog box (O5, O6) that allows the user to input the highest and lowest prices of the order window (OW). At this time, if the prices of the input corresponding to the highest price and the input corresponding to the lowest price are the same as one price, the interface unit (100) displays one price through a ruler (SC) and draws a horizontal price line corresponding to the one price. On the other hand, if the prices of the input corresponding to the highest price and the input corresponding to the lowest price are two different prices, the interface unit (100) displays two different prices (e.g., R1, R2) through the ruler (SC) and draws horizontal price lines (e.g., RL1, RL2) corresponding to the two different prices. In addition, the interface unit (100) can receive a purchase quantity through a dialog box (O7) that allows the user to input an order quantity.

[0064] In this case, if it's a buy order, the horizontal price line may be displayed as a blue line, and if it's a sell order, the horizontal price line may be displayed as a red line. Additionally, if it's a buy order, the interval between the highest and lowest buy prices may be displayed with a blue background, and if it's a sell order, the interval between the highest and lowest sell prices may be displayed with a red background.

[0065] If two different purchase prices are entered in step S130 (S120), the purchase processing unit (200) recognizes it as a split purchase and proceeds to step S140. On the other hand, if one purchase price is entered in step S120, the purchase processing unit (200) recognizes it as a single-price purchase and proceeds to step S190.

[0066]

[0067] *In the case of a split purchase, if the two different purchase prices previously input in step S140 are not classified as the highest purchase price and the lowest purchase price, the purchase processing unit (200) classifies the two different purchase prices into the highest purchase price and the lowest purchase price and stores them in the database (DB). That is, the purchase processing unit (200) designates the relatively higher price among the two different purchase prices as the highest purchase price and designates the relatively lower price as the lowest purchase price and stores them in the database (DB). Meanwhile, if the highest purchase price and the lowest purchase price have already been designated in step S140, the purchase processing unit (200) stores the highest purchase price and the lowest purchase price in the database (DB).

[0068] Next, the purchase processing unit (200) divides the price between the highest purchase price, which is a relatively high price, and the lowest purchase price, which is a relatively low price, among two different purchase prices into multiple prices at step S150.

[0069] Then, the purchase processing unit (200) converts multiple prices into multiple transaction prices at step S160 and stores them in a database (DB). Here, the transaction price refers to the unit price used for actual orders for each stock, and units such as 10 won and 100 won can be applied.

[0070] For example, in the S150 and S160 steps described above, if the highest purchase price on a stock's stock chart is 1,710 won and the lowest purchase price is 1,540 won, the difference between the highest and lowest purchase prices is 170 won. In this case, the purchase processing unit (200) can divide the price between the highest and lowest purchase prices into 11 prices. In other words, 11 purchase prices are created: 1,540 won, 1,557 won, 1,574 won, 1,591 won, 1,608 won, 1,625 won, 1,642 won, 1,659 won, 1,676 won, 1,693 won, and 1,710 won. The purchase processing unit (200) can convert the 11 purchase prices into contract prices, such as "1,540 won->1,540 won, 1,557 won->1,555 won, 1,574 won->1,570 won, 1,591 won->1,590 won, 1,608 won->1,605 won, 1,625 won, 1,642 won->1,640 won, 1,659 won->1,655 won, 1,676 won->1,675 won, 1,693 won->1,690 won, 1,710 won->1,710 won." In this way, the purchase processing unit (200) can maintain each of the divided multiple prices (11 purchase prices) as a contract price if it is a contract price, and can convert it to the contract price closest to the corresponding price if it is not a contract price.

[0071] Next, the purchase processing unit (200) distributes the purchase quantity to each of the multiple contract prices in step S170 and stores the distributed purchase quantity and the multiple contract prices as purchase orders in the database (DB). For example, if the purchase quantity is 542 shares for 11 contract prices, 54 shares can be derived by dividing the number 540, which is the number with the digit in the 1's place of 540 reset to 0, by 10, and 54 shares can be distributed to each of the 10 contract prices, and 2 shares can be distributed to the last contract price. If the number of contract prices into which prices are divided is 10, the last remaining quantity generated in the 11th is added to the purchase quantity for the 10th, and if the number of contract prices into which prices are divided is less than 10, the order quantity can be divided by the number of contract prices into which prices are divided, and then converted into an integer quantity rather than a decimal, and then assigned to each order quantity. In this way, the order execution price of the divided order and the divided order quantity corresponding to each execution price can be stored as a buy order in the database (DB).

[0072] Next, the purchase processing unit (200) purchases the stocks in installments according to the purchase quantities allocated to each of the multiple transaction prices at step S180. At this time, the purchase processing unit (200) monitors multiple sell orders in the stock market and performs installment purchases according to purchase orders stored in the database (DB) (i.e., multiple transaction prices and purchase quantities allocated to each of the multiple transaction prices).

[0073] In the case of a single purchase, the purchase processing unit (200) stores one purchase price in the database (DB) at step S190.

[0074] Then, the purchase processing unit (200) converts one purchase price into a contract price in step S200 and stores the contract price, which is a single price, and the purchase quantity corresponding to the contract price as a purchase order in the database (DB).

[0075] Next, the purchase processing unit (200) purchases the corresponding stock at step S210 based on the single price, which is the contract price, and the purchase quantity. At this time, the purchase processing unit (200) monitors multiple sell orders in the stock market, and when a sell order corresponding to a buy order stored in the database (DB) (a single price, which is the contract price, and the purchase quantity corresponding to the contract price) is searched, a single-price purchase is performed based on the searched sell order.

[0076] Next, a method for selling stocks using a sell line on a stock price chart according to an embodiment of the present invention will be described. Figure 8 is a flowchart illustrating a method for selling stocks using a sell line on a stock price chart according to an embodiment of the present invention.

[0077] Referring to FIG. 8, when a user selects one of a plurality of stocks, the interface unit (100) may provide a stock trading interface (STIF) corresponding to the stock selected by the user in step S310. As previously described with reference to FIGS. 4 to 7, the stock trading interface (STIF) basically includes a stock price chart (CT), a plurality of menu buttons (BT), an order window (OW), and a ruler (SC). In addition, the stock trading interface (STIF) may provide a drawing tool for illustrating horizontal price lines (L1, L2, L3, L4) and a reference tool for displaying a crosshair (CR1) and a stock price (CR2), etc., according to the position of a cursor corresponding to the user's operation. In addition, the stock trading interface (STIF) further includes a buy pop-up window (PPW) and a sell pop-up window (SPW) that pop up when a specific event occurs. In particular, the sell pop-up window (SPW) includes a dialog box (S1, S2) that displays the stock code number and stock name to be sold, a dialog box (S3, S4) that allows displaying or entering the highest and lowest sell prices, and a dialog box (S5) that allows entering the order quantity for the stock to be sold, i.e., the sell quantity.

[0078] The interface unit (100) can receive a selling quantity corresponding to a stock type and one selling price or two different selling prices according to the user's operation on the stock trading interface (STIF) at step S320.

[0079] According to one embodiment of step S320, the interface unit (100) can receive input of the selling quantity and selling price through input using the user's drawing tool, reference tool, and selling pop-up window (SPW). Specifically, the following is provided.

[0080] The interface unit (100) may provide a drawing tool when the user selects the automatic sell button (B3). Depending on the user's operation of the drawing tool, the interface unit (100) may draw one or two different horizontal price lines on a stock price chart (CT) through the drawing tool. When one horizontal price line is drawn on the stock price chart (CT), the interface unit (100) may receive one selling price corresponding to the drawn one horizontal price line, and when two different horizontal price lines (e.g., L3, L4) are drawn, the interface unit (100) may receive two different selling prices corresponding to the two different horizontal price lines. Before inputting the selling price through the drawing tool, the user may use a reference tool that displays a crosshair (CR1) and a stock price (CR2) so that the user can recognize the exact stock price. As described above, when one or two selling prices are entered, the interface unit (100) pops up a selling pop-up window (SPW) including a dialog box (S5) for entering the selling quantity, and according to the user's input, the selling quantity can be entered through the dialog box (S5) for entering the selling quantity.

[0081] According to another embodiment of step S320, the interface unit (100) can receive input of the selling quantity and selling price through a stock price chart and a ruler (SC) and a selling pop-up window (SPW) that allows price selection in synchronization with the price axis of the stock price chart. Specifically, the following is provided.

[0082] The interface unit (100) can activate the ruler (SC) when the user selects the automatic sell button (B3). When a price is selected by the user through the ruler (SC), the interface unit (100) can display a horizontal price line corresponding to the selected price and receive an input of a selling price corresponding to the displayed horizontal price line. Alternatively, when two different prices (e.g., R3, R4) are selected through the ruler, the interface unit (100) can display two different horizontal price lines (e.g., RL3, RL4) corresponding to the two different selected prices and receive an input of two different selling prices corresponding to the two different displayed horizontal price lines. In this way, when one or two selling prices are entered through the ruler (SC), the interface unit (100) pops up a selling pop-up window (SPW) including a dialog box (S5) for entering the selling quantity, and according to the user's input, the selling quantity can be entered through the dialog box (S5) for entering the selling quantity.

[0083] According to another embodiment of step S320, the interface unit (100) can receive a selling price through a dialog box (O5, O6) that allows the user to input the highest and lowest prices for selling in the order window (OW). At this time, if the prices of the input corresponding to the highest price and the input corresponding to the lowest price are the same as one price, the interface unit (100) displays one price through a ruler (SC) and draws a horizontal price line corresponding to the one price. On the other hand, if the prices of the input corresponding to the highest price and the input corresponding to the lowest price are two different prices, the interface unit (100) displays two different prices (e.g., R3, R4) through the ruler (SC) and draws horizontal price lines (e.g., RL3, RL4) corresponding to the two different prices. In addition, the interface unit (100) can receive a selling quantity through a dialog box (O7) that allows the user to input an order quantity.

[0084] If two different selling prices are entered in step S330 (S320), the selling processing unit (200) recognizes it as a split sale and proceeds to step S340. On the other hand, if one selling price is entered in step S320, the selling processing unit (200) recognizes it as a single-price sale and proceeds to step S390.

[0085] In the case of a split sale, if the two different selling prices previously input in step S340 are not classified as the highest selling price and the lowest selling price, the selling processing unit (200) classifies the two different selling prices into the highest selling price and the lowest selling price and stores them in the database (DB). That is, the selling processing unit (200) designates the relatively higher price among the two different selling prices as the highest selling price and designates the relatively lower price as the lowest selling price and stores them in the database (DB). Meanwhile, if the highest selling price and the lowest selling price have already been designated in step S340, the selling processing unit (200) stores the highest selling price and the lowest selling price in the database (DB).

[0086] Next, the selling processing unit (200) divides the price between the relatively high selling price (the highest selling price) and the relatively low selling price (the lowest selling price) into multiple prices at step S350. For example, similar to the division of the buying price at step S150, the price between the highest selling price and the lowest selling price can be divided into 11 prices.

[0087] Then, the selling processing unit (200) converts multiple prices into multiple contract prices at step S360 and stores them in a database (DB). For example, similar to converting each of the multiple divided prices into a contract price at step S160, if each of the multiple divided prices is a contract price, it can be maintained as is. If it is not a contract price, it can be converted to the contract price closest to the corresponding price.

[0088] Next, the selling processing unit (200) distributes the selling quantity to each of the multiple contract prices in step S370 and stores the distributed selling quantity and the multiple contract prices as a sell order in the database (DB). For example, the selling quantity can be distributed in the same way as the purchase quantity was distributed to 11 contract prices in step S170.

[0089] Next, the selling processing unit (200) divides and sells the stock according to the selling quantity allocated to each of the multiple contract prices at step S380. At this time, the selling processing unit (200) monitors multiple buy orders in the stock market and performs divided selling according to the selling orders corresponding to the sell orders stored in the database (DB) (i.e., multiple contract prices and the selling quantity allocated to each of the multiple contract prices).

[0090] In case of a single sale, the sale processing unit (200) stores one sale price in the database (DB) at step S390.

[0091] Then, the selling processing unit (200) converts one selling price into a contract price in step S400 and stores the single price, the contract price, and the selling quantity corresponding to the contract price as a sell order in the database (DB).

[0092] Next, the selling processing unit (200) sells the corresponding stock at step S410 based on the single price, which is the contract price, and the selling quantity. At this time, the selling processing unit (200) monitors multiple buy orders in the stock market, and when a buy order corresponding to a sell order stored in the database (DB) (a single price, which is the contract price, and the selling quantity corresponding to the contract price) is searched, a single-price sell is performed in response to the searched buy order.

[0093] According to an embodiment of the present invention, an automatic buy order as described with reference to FIG. 3 can be canceled, or an automatic sell order as described with reference to FIG. 8 can be canceled. FIG. 9 is a diagram illustrating a method for canceling an automatically ordered trade according to an embodiment of the present invention.

[0094] Referring to FIG. 9, when a user selects the automatic purchase cancellation button (B2) on the stock trading interface (STIF), the interface unit (100) provides an automatic purchase order cancellation page as shown in (A) of FIG. 9. The automatic purchase order cancellation page provides details of one or more automatic purchase orders, an individual cancellation button (PIC) for canceling each automatic purchase order, and a full cancellation button (PAC) for canceling all automatic purchase orders. When the user selects the individual cancellation button (PIC) or the full cancellation button (PAC) on the automatic purchase order cancellation page, the purchase processing unit (200) cancels the corresponding individual automatic purchase order or all automatic purchase orders. At this time, for items that have not been concluded, when the cancel button (PIC or PAC) is selected, the information and the purchase order on the automatic purchase order cancellation page are deleted, and then the purchase line is deleted, and for items that are being concluded, only the remaining amount excluding the concluded quantity from the order quantity is deleted, and then the purchase line is deleted.

[0095] In addition, when the user selects the automatic sell cancel button (B4) on the stock trading interface (STIF), the interface unit (100) provides an automatic sell order cancellation page such as (B) of FIG. 9. The automatic sell order cancellation page provides details of one or more automatic sell orders, an individual cancel button (SIC) for canceling each automatic sell order, and a full cancel button (SAC) for canceling all automatic sell orders. When the user selects the individual cancel button (SIC) or the full cancel button (SAC) on the automatic sell order cancellation page, the selling processing unit (300) cancels the corresponding individual automatic sell order or all automatic sell orders. At this time, for items that have not been concluded, when the cancel button (SIC or SAC) is selected, the information on the automatic sell order cancellation page and the sell order are deleted, and the sell line is deleted, and for items that are being concluded, only the remaining amount excluding the concluded quantity from the order quantity is deleted, and then the sell line is deleted.

[0096] According to an embodiment of the present invention, an automatic buy order as described with reference to FIG. 3 or an automatic sell order as described with reference to FIG. 8 can be corrected. FIG. 10 is a diagram illustrating a method for correcting an automatically ordered trade according to an embodiment of the present invention.

[0097] Referring to FIG. 10, when a user selects the automatic buy / sell correction button (B5) on the stock trading interface (STIF), the interface unit (100) provides an automatic buy / sell correction page as shown in FIG. 10.

[0098] The automatic buy / sell correction page includes an automatic buy registration sheet and an automatic sell registration sheet.

[0099] The automatic purchase registration form provides detailed information for each of multiple automatic purchase orders and a corresponding edit button for each of the multiple automatic purchase orders. Here, the detailed information for each automatic purchase order includes at least the order price (purchase price) and order quantity (purchase quantity).

[0100] The automatic sell registration form provides detailed information for each of multiple automatic sell orders and a corresponding edit button. The detailed information for each automatic sell order includes at least the order price (sell price) and order quantity (sell quantity).

[0101] A user may input the order price (buy price or sell price) and order quantity (buy quantity or sell quantity) of an automatic buy order or automatic sell order to be corrected in the automatic buy registration table or automatic sell registration table, and select the correction button. Then, the purchase processing unit (200) or the sale processing unit (300) corrects the details corresponding to the user's input, i.e., the order price (buy price or sell price) and order quantity (buy quantity or sell quantity).

[0102] According to an embodiment of the present invention, it is possible to confirm an automatic buy order as described with reference to FIG. 3 and an automatic sell order as described with reference to FIG. 8. FIG. 11 is a diagram illustrating a method for confirming an automatically ordered trade according to an embodiment of the present invention.

[0103] Referring to FIG. 11, when a user selects the automatic buy / sell confirmation icon (B6) on the stock trading interface (STIF), the interface unit (100) provides an automatic buy / sell confirmation page as shown in FIG. 11.

[0104] The automatic buy / sell confirmation page includes an automatic buy confirmation table and an automatic sell confirmation table. The automatic buy confirmation table provides information on the execution status of each of multiple automatic buy orders. The automatic sell confirmation table provides information on the execution status of each of multiple automatic sell orders. The automatic buy / sell confirmation page also includes an account balance check button, allowing you to check your account balance.
