TECHNICAL FIELD

[0001] The present application generally relates to the field of data processing, and particularly relates to an option expiration clearing method, device, equipment and medium. BACKGROUND

[0002] As a financial instrument, options have gradually become a popular investment and asset management direction. In the process of option trading, it is usually necessary to monitor the asset status of the user account. If the assets of the user account are negative after the exercise on the option expiration date, it will cause the user account to be abnormal, and will also cause the asset loss risk of the broker.

[0003] In the related art, once the assets of the user account are negative after the exercise on the option expiration date, the user's option position can be manually cleared; or the net asset ratio after the exercise is calculated based on the assets of the user, and the user's option position is automatically cleared based on the net asset ratio to correct possible abnormalities and risks.

[0004] However, the manual clearing method requires a large amount of human cost, and the real-time performance is difficult to guarantee when the user's option position is large. The clearing method based on the net asset ratio of the user depends on more, needs to determine the influence of the exercise on cash, the number of shares and the market value, and has high complexity.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that only the parts related to the application are shown in the drawings for ease of description.

[0032] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] Figure 1 is an implementation environment architecture diagram of an option expiration settlement method provided by an embodiment of the present application. As shown in Figure 1 The implementation environment architecture includes a first terminal device 110 and at least one second terminal device 120, a wired or wireless network communication connection is established between the first terminal device 110 and each second terminal device 120, and the first terminal device 110 and the second terminal device 120 can be a computer or a server with data processing capability.

[0034] The first terminal device 110 is configured to store an option information table of a user. The option information table can store option transaction information of at least one user account, and the option transaction information at least includes a user account, an option type corresponding to the user account, an option holding number of different types of options, and an expiration date of different types of options. The first terminal device 110 can determine whether the current date is the expiration date of the option of the user account based on the option contract information table, and if so, the option contract information of the user can be sent to at least one second terminal device 120 according to a preset fragmentation rule.

[0035] The second terminal device 120 is configured to receive the option contract information of the user, determine the exercise calculation result of the expiration option holding corresponding to each user account, and determine whether the user account needs to be settled based on the user account type and the exercise calculation result. If so, the option holding of the user account is settled based on a preset settlement rule.

[0036] It should be noted that in the embodiments of the present application, the preset sharding rule is used to send the option transaction information of the users with expiring option positions on the same day to at least one server for sharding processing, so as to ensure the fast and efficient performance of the option expiration clearing process. The preset sharding rule can be determined based on actual needs, and the embodiments of the present application do not limit this.

[0037] For example, it is assumed that the first terminal device determines that there are 1000 users with expiring option positions on a certain day, and the 1000 users can be divided into 5 groups, each group having 200 users. The option transaction information of the 200 users is sent to 5 second terminal devices to perform option expiration clearing for the 1000 users, which can ensure the timeliness of the user option expiration clearing.

[0038] The embodiments of the present application provide an option expiration clearing method, which can be applied to the above-mentioned second terminal device. The method can be applied to clearing the expiration options of American stocks, as shown in the following table. Figure 1 The method comprises the following steps:

[0039] Step 201: Obtain the exercise calculation result of the user account.

[0040] In this step, for each user, after determining the exercise calculation result corresponding to the user account, the exercise calculation result of the user account needs to be obtained.

[0041] It should be noted that in the embodiments of the present application, the user account is divided into two types, namely, a non-financing account and a financing account. For the non-financing account, the exercise calculation result can include: the current cash amount (Cash-Now) corresponding to the user account, the change amount of the cash amount (CashEffect-X-N) of the user account after the Nth option of the option of type X is exercised, the current position quantity (QTY-X-now) of the option of type X, and the change amount of the position quantity (QTY Effect-X-N) of the user account after the Nth option of the option of type X is exercised. For the financing account, the exercise calculation result can include: the current account risk control value (T-now) corresponding to the user account, and the change amount of the account risk control value (T Effect-X-N) of the user account after the Nth option of the option of type X is exercised. The account risk control value (T) can be an overnight risk control value (Special Memorandum Account; SMA) or an intraday risk control value. The overnight risk control value is also called a special memorandum account, and the intraday risk control value is also called a current remaining liquidity.

[0042] Step 202: Determine whether the user account needs to be cleared based on the type of the user account and the exercise calculation result.

[0043] In this step, the process of determining whether the user account needs to perform option position liquidation based on the user account type and the exercise calculation result can have the following two optional implementation manners:

[0044] In an optional implementation manner, if the user account is a non-financed account, the process of determining whether the user account needs to perform option position liquidation based on the user account type and the exercise calculation result can include: determining the liquidated present amount corresponding to the user account and the exercised position quantity of at least one type of option based on the exercise calculation result; determining whether the liquidated present amount and / or the exercised position quantity of at least one type of option is negative; if yes, determining that the user account needs to perform option position liquidation, otherwise, determining that the user account does not need to perform option position liquidation. Wherein, the exercised position quantity of each type of option is the position quantity of the type of option in the user account after each option corresponding to the type of option is exercised.

[0045] Wherein, the process of determining the liquidated present amount corresponding to the user account based on the exercise calculation result can include:

[0046] parsing the exercise calculation result to obtain a current present amount corresponding to the user account and a plurality of first reference values; determining a sum value of the plurality of first reference values corresponding to the same type of option to obtain a first comprehensive variable value corresponding to the same type of option; determining a sum value of the first comprehensive variable value corresponding to each type of option and the current present amount to obtain a liquidated present amount corresponding to the user account, the first reference value being a present amount change amount of the user account after any option corresponding to at least one type of option is exercised.

[0047] Wherein, the process of determining the exercised position quantity of at least one type of option corresponding to the user account based on the exercise calculation result includes:

[0048] parsing the exercise calculation result to obtain a current position quantity of at least one type of option corresponding to the user account and a plurality of second reference values associated with each type of option; determining a sum value of the plurality of second reference values corresponding to the same type of option to obtain a second comprehensive variable value corresponding to the same type of option; determining a sum value of the second comprehensive variable value corresponding to the same type of option and the current position quantity to obtain the exercised position quantity of at least one type of option corresponding to the user account, the second reference value being a position quantity change amount of the option corresponding to the type of option after any option corresponding to each type of option is exercised.

[0049] For example, assuming that the option types corresponding to the user account Q1 include A-type options, B-type options, C-type options and D-type options, and it is determined that the A-type options, B-type options and C-type options expire on the current date, the exercise calculation result of the user account Q1 can be obtained.

[0050] Since the user account Q1 is a non-financed account, the obtained exercise calculation result of the user account Q1 includes: a current cash amount (Cash-Now) corresponding to the user account Q1, a plurality of first reference values and a plurality of second reference values, wherein the plurality of first reference values include: a cash amount change amount (Cash Effect-A-i) of the user account after the i-th option of the A-type options is exercised, a cash amount change amount (Cash Effect-B-i) of the user account after the i-th option of the B-type options is exercised, and a cash amount change amount (Cash Effect-C-i) of the user account after the i-th option of the C-type options is exercised; and the plurality of second reference values include: a current holding quantity (QTY-A-now) of the A-type options, a holding quantity change amount (QTY Effect-A-i) of the A-type options after the i-th option of the A-type options is exercised; a current holding quantity (QTY-B-now) of the B-type options, a holding quantity change amount (QTY Effect-B-i) of the B-type options after the i-th option of the B-type options is exercised; and a current holding quantity (QTY-C-now) of the C-type options, a holding quantity change amount (QTY Effect-C-i) of the C-type options after the i-th option of the C-type options is exercised.

[0051] The first comprehensive variable value corresponding to the A-type options can be determined as:

[0052]

[0053] The first comprehensive variable value corresponding to the B-type options is:

[0054]

[0055] The first comprehensive variable value corresponding to the C-type options is:

[0056]

[0057] The post-settlement cash amount (Cash-After) corresponding to the user account Q1 is:

[0058]

[0059] The exercised holding quantity (QTY-A-After) of the A-type options corresponding to the user account Q1 is:

[0060]

[0061] The exercised holding quantity (QTY-B-After) of the B-type options corresponding to the user account Q1 is:

[0062]

[0063] The number of shares (QTY-C-After) of the C-type option corresponding to the user account Q1 after the exercise is:

[0064]

[0065] wherein i is the i-th option corresponding to the A-type option, the B-type option and the C-type option respectively, and n is the total number of shares of the options corresponding to the A-type option, the B-type option and the C-type option respectively.

[0066] In another optional implementation, the user account is a financable account, and the process of determining whether the user account needs to perform the option position settlement based on the user account type and the exercise calculation result can include: determining the account risk control value after settlement corresponding to the user account based on the exercise calculation result; determining whether the account risk control value after settlement is negative; if yes, determining that the user account needs to perform the option position settlement, otherwise, determining that the user account does not need to perform the option position settlement.

[0067] wherein the account risk control value after settlement corresponding to the user account is determined based on the exercise calculation result, including:

[0068] parsing the exercise calculation result to obtain the current account risk control value corresponding to the user account and a plurality of fifth reference values; determining the sum of the plurality of fifth reference values corresponding to the same type of options to obtain the third comprehensive variable value corresponding to the same type of options; determining the sum of the third comprehensive variable value corresponding to each type of option and the current account risk control value to obtain the account risk control value after settlement corresponding to the user account, wherein the fifth reference value is the account risk control value change of the user account after any option corresponding to at least one type of option is exercised.

[0069] For example, assuming that the option types corresponding to the user account Q2 include the A-type option, the B-type option, the C-type option and the E-type option, and it is determined that the A-type option, the B-type option and the C-type option expire on the current date, the exercise calculation result of the user account Q2 can be obtained.

[0070] Since the user account Q2 is a non-financable account, the account risk control value is the overnight risk control value, and the obtained exercise calculation result of the user account Q2 includes: the current account risk control value (SMA-now) corresponding to the user account and a plurality of fifth reference values, wherein the plurality of fifth reference values include: the account risk control value change (SMA Effect-A-i) of the user account after the i-th option in the A-type option is exercised, the account risk control value change (SMA Effect-B-i) of the user account after the i-th option in the B-type option is exercised, and the account risk control value change (SMA Effect-C-i) of the user account after the i-th option in the C-type option is exercised.

[0071] The post-settlement account risk control value (SMA-After) corresponding to user account Q2 is:

[0072]

[0073] Where i represents the i-th option corresponding to Class A, Class B, and Class C options, and n represents the total number of shares held for Class A, Class B, and Class C options.

[0074] Step 203: If so, liquidate the user account's option positions based on the preset liquidation rules.

[0075] In this step, the process of clearing the user's option positions based on preset clearing rules can be implemented in the following two ways:

[0076] In one alternative implementation, the user account is a non-financing account, such as... Figure 3 As shown, the process of clearing a user's option positions based on preset clearing rules may include:

[0077] Step S11: Close out each option corresponding to the first target type to obtain multiple third reference values.

[0078] In this embodiment of the application, the first target type is the option type corresponding to the negative value of the first comprehensive variable, and the third reference value is the change in the cash amount of the user's account after any option corresponding to the first target type is closed out. For example, the third reference value (cash-Liquidation Effect-XN) represents the change in the cash amount of the user's account after the Nth option of type X is forcibly closed out.

[0079] It should be noted that, in the embodiments of this application, there may be more than one option type corresponding to a negative value of the first comprehensive variable. Any option type among the option types corresponding to a negative value of the first comprehensive variable can be determined as the first target type.

[0080] Step S12: Determine the updated post-settlement cash amount corresponding to the user account based on multiple third reference values.

[0081] In this step, the process of determining the updated post-settlement cash amount corresponding to the user account based on multiple third reference values ​​can be as follows: determine the sum of multiple third reference values ​​corresponding to the first target type, determine the sum of the multiple third reference values, the current cash amount, and the sum of the first comprehensive variable values ​​of other types of options corresponding to the user account, and obtain the updated post-settlement cash amount corresponding to the user account.

[0082] For example, assuming that the first comprehensive variable value corresponding to the A-type option of the user account Q1 is negative, the A-type option is determined as the first target type of option, and the user account Q1 is liquidated based on each option corresponding to the A-type option, the third reference value is cash-Liquidation Effect-A-i, and the updated liquidation present amount corresponding to the user account Q1 is:

[0083]

[0084]

[0085] wherein i is the i-th option corresponding to the A-type option, the B-type option and the C-type option, and n is the total number of options corresponding to the A-type option, the B-type option and the C-type option.

[0086] Step S13, determining whether the updated liquidation present amount corresponding to the user account is greater than or equal to 0.

[0087] Step S14, if not, determining the updated first target type, and repeating the above operation until the updated liquidation present amount corresponding to the user account is greater than or equal to 0.

[0088] In this step, the process of determining the updated first target type can be: determining any option type other than the first target type as the updated first target type corresponding to the user account. If there is more than one first comprehensive variable value with a negative value corresponding to the user account, the option type corresponding to the first comprehensive variable value with a negative value should be selected as the priority in the process of updating the first target type, so as to ensure that the option most likely to cause economic loss of the user account is liquidated and the user's revenue is maximized. It can be understood that the updated first target type is not repeated before the first target type is updated.

[0089] For example, for the user account Q1, assuming that the first comprehensive variable value corresponding to the A-type option is negative, the first comprehensive variable values corresponding to the B-type option and the C-type option are positive, and the currently determined first target type is the A-type option, the updated first target type is determined as the B-type option or the C-type option.

[0090] Assuming that the first comprehensive variable values corresponding to the A-type option and the B-type option are negative, and the first comprehensive variable values corresponding to the C-type option are positive, and the currently determined first target type is the A-type option, the updated first target type is determined as the B-type option.

[0091] Step S15, if yes, liquidating the option position of the user account based on each option corresponding to the first target type.

[0092] In this step, the process of determining the updated post-settlement cash amount corresponding to the user account based on the fourth reference value can include:

[0093] Step S151, close the position of the first target option to obtain a fourth reference value.

[0094] In the embodiments of the present application, the first target option is any option corresponding to the first target type, and the fourth reference value is the change in the current cash amount of the user account after the first target option is closed.

[0095] Step S152, determine the updated post-settlement cash amount corresponding to the user account based on the fourth reference value.

[0096] In this step, the process of determining the updated post-settlement cash amount corresponding to the user account based on the fourth reference value can be: determining the sum of the fourth reference value, the current cash amount, the plurality of first reference values associated with the remaining options corresponding to the first target type, and the first comprehensive variable value of the other types of options corresponding to the user account, to obtain the updated post-settlement cash amount corresponding to the user account.

[0097] Step S153, determine whether the updated post-settlement cash amount corresponding to the user account is greater than or equal to 0.

[0098] Step S154, if not, determine the updated first target option and repeat the above operations until the updated post-settlement cash amount corresponding to the user account is greater than or equal to 0.

[0099] In this step, the process of determining the updated first target option can be: determining any remaining option corresponding to the first target type as the updated first target option.

[0100] It should be noted that in the embodiments of the present application, for the updated first target option, in the process of repeating step S152, the process of determining the updated post-settlement cash amount corresponding to the user account based on the third reference value can be: determining the sum of at least two third reference values, determining the sum of at least two third reference values, the current cash amount, the plurality of first reference values associated with the remaining options corresponding to the first target type, and the first comprehensive variable value of the other types corresponding to the user account, to obtain the updated post-settlement cash amount corresponding to the user account. Wherein, the at least two third reference values include the third reference value associated with each first target option corresponding to the first target type, and the remaining options corresponding to the first target type do not include the option previously determined as the first target option.

[0101] Step S155, if yes, determining the updated exercised position quantity of the first target type option; judging whether the updated exercised position quantity of the first target type option is greater than or equal to 0; if yes, determining that the option position of the user account is settled; if no, repeating the above operation until the option position of the user account is settled.

[0102] In this step, the process of determining the updated exercised position quantity of the first target type option can be: determining the sum of the second reference value associated with each option that is not determined as the first target option and the current position quantity in all options corresponding to the first target type, to obtain the updated exercised position quantity of the first target type option.

[0103] For example, for the user account Q1, assuming that the A-type option is the first target type target type option, and in the above step S13, it is determined that the updated post-settlement cash amount corresponding to the user account Q1 is greater than 0, any option from the A-type option is selected as the first target option for hedging processing, to obtain the fourth reference value, and it is determined that the updated post-settlement cash amount (Cash-After") is:

[0104]

[0105]

[0106] wherein i is the ith option corresponding to the A-type option, the B-type option and the C-type option, n is the total option position quantity corresponding to the A-type option, the B-type option and the C-type option, and j represents the number of the first target options.

[0107] If the updated post-settlement cash amount (Cash-After") is less than 0, any option from the A-type option is reselected as the updated first target option, and the above process is repeated until the updated post-settlement cash amount (Cash-After") is greater than or equal to 0.

[0108] If the updated post-settlement cash amount (Cash-After") is greater than or equal to 0, the updated exercised position quantity of the first target type option can be determined as:

[0109]

[0110] wherein i is the ith option corresponding to the A-type option, n is the total option position quantity corresponding to the A-type option, and j represents the number of the first target options.

[0111] determining whether the updated exercise position quantity (QTY-A-After') of the first target type option is greater than or equal to 0; if yes, determining that the option position of the user account is liquidated; if no, repeating the above operations until the option position of the user account is liquidated.

[0112] In another optional implementation, the user account is a financable account, such as Figure 4 As shown, the process of liquidating the option position of the user account based on the preset liquidation rule can include:

[0113] Step S21, performing a closing transaction on each option corresponding to the second target type to obtain a plurality of sixth reference values.

[0114] In the embodiments of the present application, the second target type is the type of option corresponding to the third comprehensive variable value being negative, and the sixth reference value is the change amount of the account risk control value of the user account after any option corresponding to the second target type is closed, for example, the sixth reference value (T-Liquidation Effect-X-N) represents the change amount of the account risk control value of the user account after the Nth option of the type X is forced to be closed.

[0115] It should be noted that in the embodiments of the present application, there can be more than one type of option corresponding to the second comprehensive variable value being negative, and any one of the types of options corresponding to the second comprehensive variable value being negative can be determined as the second target type.

[0116] Step S22, determining the updated post-liquidation account risk control value corresponding to the user account based on the plurality of sixth reference values and the updated current account risk control value.

[0117] In this step, the process of determining the updated post-liquidation account risk control value corresponding to the user account based on the plurality of sixth reference values and the updated current account risk control value can be: determining the sum of the plurality of sixth reference values corresponding to the second target type, determining the sum of the plurality of sixth reference values and the updated current account risk control value, and the sum of the second comprehensive variable values of other types of options corresponding to the user account, to obtain the updated post-liquidation account risk control value corresponding to the user account.

[0118] It should be noted that in the embodiments of the present application, for the account risk control value, the account risk control value needs to be determined again after each closing transaction to accurately liquidate the assets of the user account.

[0119] For example, assuming that the second comprehensive variable value of the A-type option corresponding to the user account Q2 is negative, it is determined that the A-type option is the second target type option, and each option corresponding to the A-type option is liquidated to obtain a plurality of sixth reference values SMA-Liquidation Effect-A-i, and the updated account risk value of the user account Q2 after liquidation is:

[0120]

[0121]

[0122] wherein i is the i-th option corresponding to the A-type option, the B-type option and the C-type option, and n is the total number of option positions corresponding to the A-type option, the B-type option and the C-type option.

[0123] Step S23, determining whether the updated account risk value corresponding to the user account after liquidation is greater than or equal to 0.

[0124] Step S24, if not, determining an updated second target type, and repeating the above operations until the updated account risk value corresponding to the user account after liquidation is greater than or equal to 0.

[0125] In this step, the process of determining the updated second target type can be: determining any option type other than the second target type as the updated second target type corresponding to the user account. If there is more than one second comprehensive variable value with a negative value corresponding to the user account, the option type corresponding to the second comprehensive variable value with a negative value should be selected as a priority in the process of updating the second target type, so as to ensure liquidation of the option most likely to cause economic loss of the user account and maximize the user's revenue. It can be understood that the updated second target type is not repeated before updating.

[0126] Step S25, if yes, liquidating the option position of the user account based on each option corresponding to the second target type.

[0127] In this step, the process of liquidating the option position of the user account based on each option corresponding to the second target type can include:

[0128] Step S251, liquidating the second target option to obtain a seventh reference value,

[0129] In the embodiment of the present application, the second target option is the option with the smallest profit and loss value corresponding to the second target type, and the seventh reference value is the change amount of the account risk value of the user account after the second target option is liquidated. Among them, selecting the option with the smallest profit and loss value as the second target option can maximize the user's revenue and protect the user's option income.

[0130] Step S252, determining an updated post-settlement account risk control value corresponding to the user account based on the seventh reference value and the updated current account risk control value.

[0131] In this step, the process of determining the updated post-settlement account risk control value corresponding to the user account based on the seventh reference value and the updated current account risk control value can be: determining the sum of the seventh reference value and the updated current account risk control value, a plurality of fifth reference values associated with the remaining options corresponding to the second target type, and the second comprehensive variable value of the other type of options corresponding to the user account, to obtain the updated post-settlement account risk control value corresponding to the user account. Wherein, the remaining options corresponding to the second target type do not include the options previously determined as the second target options.

[0132] Step S253, determining whether the updated post-settlement account risk control value corresponding to the user account is greater than or equal to 0.

[0133] Step S254, if not, determining the updated second target options, repeating the above operations until the updated post-settlement account risk control value corresponding to the user account is greater than or equal to 0.

[0134] In this step, the process of determining the updated second target options can be: determining the option with the smallest profit and loss value among the remaining options corresponding to the second target type as the updated first target option.

[0135] It should be noted that in the embodiments of the present application, for the updated second target options, in the process of repeating the above step S252, the process of determining the updated post-settlement account risk control value corresponding to the user account based on the seventh reference value and the updated current account risk control value can be: determining the sum of at least two seventh reference values, determining the sum of at least two seventh reference values and the updated current account risk control value, a plurality of fifth reference values associated with the remaining options corresponding to the second target type, and the second comprehensive variable value of the other type corresponding to the user account, to obtain the updated post-settlement account risk control value corresponding to the user account. Wherein, the at least two seventh reference values include the seventh reference value associated with each second target option corresponding to the second target type, and the remaining options corresponding to the second target type do not include the options previously determined as the second target options.

[0136] Step S254, if yes, determining that the option position settlement of the user account is completed.

[0137] For example, for the user account Q2, assuming that the A-type option is the second target option type Target Type Option, and in step S23, it is determined that the updated account risk control value corresponding to the user account Q2 is greater than 0, the option with the smallest profit and loss value is selected from the A-type options as the second target option for the closing process, the seventh reference value is obtained, and it is determined that the updated clearing account risk control value (SMA-After') is:

[0138]

[0139]

[0140] wherein i is the ith option corresponding to the A-type option, the B-type option and the C-type option, n is the total number of options corresponding to the A-type option, the B-type option and the C-type option, and j represents the number of the second target options.

[0141] If the updated clearing account risk control value (SMA-After') is less than 0, the option with the smallest profit and loss value is selected from the remaining options corresponding to the A-type option as the updated second target option, and the above process is repeated until the updated clearing account risk control value (SMA-After') is greater than or equal to 0.

[0142] In the embodiments of the present application, for any user account, the expiring options of the user account are determined on the current date, for the expiring options, it can be predicted in advance whether the expiring options are options with potential risks, and the expiring options with potential risks are closed to ensure normal user assets and avoid risks to the securities company.

[0143] wherein the process of predicting whether the expiring options are options with potential risks can have the following two optional implementation manners:

[0144] In one optional implementation manner, the process includes: determining whether any option corresponding to the user account is a low-liquidity option; if yes, determining that the low-liquidity option is a third target option; and closing the third target option.

[0145] The determining whether any option corresponding to the user account is a low-liquidity option comprises: determining whether a bid price (Bid) of any option corresponding to the user account is 0; if yes, determining that the option is a low-liquidity option; if no, determining a price change rate of the option, the price change rate being a ratio of a difference between an ask price (Ask) of the option and the bid price of the option to the bid price of the option; if the price change rate is greater than or equal to a price change rate threshold value and a remaining contract number (Open Interest) of the option is less than or equal to a contract number threshold value, determining that the option is a low-liquidity option. The price change rate threshold value and the contract number threshold value can be determined based on actual needs, and embodiments of the present application do not limit this.

[0146] In another possible implementation, the process comprises: determining an option type of any option corresponding to the user account; determining an underlying asset estimated value of the option based on the option type; determining whether the option has a price change risk based on a size relationship between the underlying asset estimated value and an option strike price of the option; and if yes, closing the option.

[0147] Optionally, if the option type is a call option (CALL), the underlying asset estimated value of the option is a highest underlying asset estimated price (Predict-High) of the option:

[0148] Predict-High = High x (1 + 4% x MR);

[0149] wherein High is a highest price of a stock on which the option depends on on an expiration date of the option, and MR is a maintenance margin coefficient, which is provided by a broker, and embodiments of the present application do not limit this.

[0150] Further, if the highest underlying asset estimated price (Predict-High) of the option is greater than or equal to the option strike price, it is determined that the option has the price change risk, and the option is closed; otherwise, it is determined that the option does not have the price change risk.

[0151] Optionally, if the option type is a put option (PUT), the underlying asset estimated value of the option is a lowest underlying asset estimated price (Predict-Low) of the option:

[0152] Predict-Low = Low x (1 - 4% x MR);

[0153] wherein Low is a lowest price of a stock on which the option depends on on the expiration date of the option, and MR is the maintenance margin coefficient, which is provided by the broker, and embodiments of the present application do not limit this.

[0154] Further, if the predicted minimum price (Predict-Low) of the underlying asset of the option is less than or equal to the option exercise price of the option, it is determined that the option has a price change risk, and the option is closed; otherwise, it is determined that the option does not have a price change risk.
