Description

  The present invention relates to a trading order automatic correction system for automatically correcting a trading order of a financial product that is commissioned by an orderer to a trading market for a product whose price fluctuates, such as stocks, bonds, and commodity futures. is there.

  On the back of the widespread use of the Internet and the full liberalization of stock brokerage commissions, online trading of financial products such as stocks using the Internet has rapidly expanded from around 1999 to individual investors. Under such circumstances, many securities companies have entered online trading, and are working to improve the convenience of services and enhance information provision.

  Stock trading is conducted at securities exchanges and over-the-counter markets through securities companies. Generally, when an investor entrusts buying and selling to a securities company, a market order that designates buying and selling without specifying a price and a price are specified. Then, the limit order entrusted to buy and sell can be selected. Also in the above online transaction, it is general that either a market order or a limit order can be selected and ordered from a terminal screen.

  Under such circumstances, the applicant of the present application has established a unique online transaction system that can select several ordering methods with conditions other than market orders and limit orders, and provides services (Non-Patent Documents). 1). In this system, “Condition order” that specifies the timing of placing an order or stock price as a condition, “Condition order” that sets the condition in the opposite direction to the limit price in “Conditional order”, and the execution condition of other orders "Relay order" for placing the next order in the order, "U-turn order" for reserving a sell order at the same time as a buy order, "W limit order" for correcting conditions under certain conditions while being a limit order, etc. As a result, investors can manage the price fluctuation risk of financial products by utilizing various trading methods.

  All of these conditional orders are in the form of orders that cannot be accepted on domestic stock exchanges, but they depend on the order form determined by the exchange by conducting conditional control at the brokerage that manages the trading. This is possible for the first time without doing so. This condition control becomes more difficult to monitor in a conventional securities company that is manually performed as the conditions are diversified, and it is particularly difficult to monitor whether the conditions are fulfilled. Among the above-mentioned orders, the present applicant implements “conditional order”, “stop order”, “relay order”, and “U-turn order” that specify ordering conditions by trigger monitoring that specifies ordering conditions. . (See Patent Document 1).

  In the above invention, when the stock price, time, and other order execution are specified as the ordering conditions, the market price, time, and order execution status are monitored in real time using these as triggers. To do. By automating the condition monitoring using the trigger as described above, it is possible to accept a conditional order for placing an order when the condition specified by the investor is reached.

  On the other hand, a “W limit order” that corrects the limit conditions under certain conditions while placing a limit order is placed as a conditional order as follows. In the example of FIG. 3, if a buy order for a stock price of 500 yen from a certain investor is executed and if the investor wants to determine profit if he achieves a profit margin of 50 yen, he places a sell order of 550 yen. become. The stock price will rise as it is, and it may be executed at 550 yen as in the example of FIG. 3, but conversely, how to avoid the risk that the stock price will fall and the loss will increase will be a problem.

  Therefore, in the “W limit order”, a condition that “if the stock price becomes 480 yen, it is corrected to a sell order with a limit price of 475 yen” can be attached. In the example of Fig. 4, if the stock price falls unexpectedly, it will be corrected to a selling order of 475 yen when it reaches 480 yen, so the loss of this investor is the range when selling at a maximum of 475 yen It will be suppressed to.

  In this “W limit order”, no particular condition is specified for ordering, and unlike the “conditional order” example in which the ordering condition is specified, there is no trigger for ordering. . On the other hand, since it is necessary to correct the order condition when a certain condition is satisfied, the system provided by the applicant of the present application is provided with a trigger for correcting the order condition.

  In the above system, when the stock price, time, and other order execution are specified as correction conditions, the market price, time, and order execution status are monitored in real time using these as triggers. correct. By automating the monitoring of conditions using triggers in this way, it is possible to accept orders with correction conditions for correcting orders when the conditions specified by the investor are reached.

  An object of the present invention is to provide a trading order automatic correction system for automatically correcting a trading order of a financial product that has been commissioned by an orderer and placed in a trading market.

An invention for solving the problems of the present application is a trading order automatic correction system for automatically correcting a limit price designated in a trading order of a financial product commissioned by an orderer to a trading market, The limit price based on the contract price of the first trade order designated by the orderer with respect to execution of the second trade order in which the contract of the first trade order is designated as an order condition for placing an order to the order contents of the second trade orders including the order contents storing means for storing assigned the identification information of the second trading order, the ordering trigger to order the second trading orders in trading market Order contract storage means for storing the identification information of the first trading order in association with the identification information of the second trading order for the execution of the first trading order, and the second trading order is ordered Later the second With correction price the relative to the agreed price for the specified first trading orders from the orderer to correct the limit price trading orders, to correct the limit price of the second trading order to the correct price Therefore, a correction trigger for storing a correction specified price based on the contract price of the first trading order, which is a correction condition specified by the orderer, as a correction trigger in association with the identification information of the second trading order In the storage means and the contract information storage device for storing the contract information regarding the contract status of the trade order including the first trade order, monitoring that the contract of the trade order is recorded in the contract information regarding the first trade order And when the contract information monitoring means detects that the contract of the order is recorded in the contract information relating to the first trade order, the first trade note The identification information of the second buy / sell order corresponding to the order trigger storing means is specified using the identification information of the order as a key, and the buy / sell corresponding to the identification information of the second buy / sell order stored in the order content storing means. For the order, the limit price designated for the second trading order is updated to reflect the contract price of the first trading order, and the second trading order stored in the correction trigger storage means is identified. Condition correction means for identifying a correction trigger corresponding to the information and updating the correction price designated as the correction trigger and the correction designated price to reflect the contract price of the first buy / sell order, and updating by the condition update means In accordance with the order content stored in the order content storage means, the execution instruction of the buy / sell order specifying the limit price included in the order content is sent to the transaction market system for financial products. And monitoring whether the data changing in the market price storage device for storing the information related to the market price of the financial product matches the correction specified price specified in the correction trigger stored in the correction trigger storage means. When the correction trigger monitoring means and the correction trigger monitoring means detect that the correction specified price matches, the correction trigger stored in the order content storage means corresponds to the second trading order identification information as a key. identifying a second trading orders, updates the limit price specified on the execution of the second trading orders correct price corresponding to the correction trigger acquired from the correction trigger storing means, the second trading Order correction means for transmitting a correction instruction for correcting the limit price of the order to the correction price to the trading market system. Is a buy and sell order auto-correction system to be.

  The “financial products” to be considered here are typically financial products such as stocks, bonds, and options, but may be commodity futures as long as they are bought and sold in a trading market. The “trading market” is not limited to an exchange operated by a member organization such as a stock exchange, as long as it is a market in which the above products can be traded between brokers such as securities companies. In some cases, the issuer may act as a trading market.

  The “order condition” is a condition specified for execution of a buy / sell order, such as “sell 100 shares at market” or “buy 100 shares at the limit of Y yen”. The “correction condition” is a condition specified for correcting the ordered order, such as “change the limit price to W yen when the price becomes Z yen”.

  The target to be monitored by the correction trigger may be any of the commodity price such as stock price, the timing of the time in the market such as closing, and the status of owned assets such as unrealized gains and losses.

  If an investor owns multiple units of a stock and wants to sell a part of it after adding a certain margin if there is a certain amount of unrealized gain as a whole, “Unrealized gain for stock A is X yen. If the price exceeds A, it is possible to specify that the order condition is to be corrected to “a sell order of 100 shares at the current value of the A brand + the limit of Y yen at that time”.

  Incidentally, the present invention can be configured as an automatic correction method of a trade order using such a system in correspondence with the automatic trade order correction system according to the present invention.

  According to the present invention, it becomes possible for an investor to place an order with a correction condition in which the order condition is automatically corrected, and it is possible to reduce the monitoring burden on the market etc. and the work burden for setting the correction condition. These burden reductions have the effect of facilitating risk management of investments even for individual investors who are not investment specialists, and fostering individual investors and fostering investor protection that are currently required in Japan. It also helps.

  For brokerage firms such as securities firms, there is an effect of improving customer service by providing market infrastructure that can meet the needs of various investors. Since it is difficult to accept orders with complicated correction conditions because a large number of orders must be processed accurately on the exchange, such correction conditions are used by brokers such as securities companies. It is extremely effective to provide the control function.

  Embodiments of the present invention will be described below in detail with reference to the drawings. Here, an example in which a securities company handles trading orders for stocks will be described. However, the present invention is not limited to a securities company as long as it distributes products whose prices fluctuate. included. Further, the products handled are not limited to stocks, and the triggers to be set are not limited to the examples described below.

  FIG. 1 shows an outline when a securities company uses a trading order processing system according to the present invention. In online securities trading using the Internet, a securities company system connected to a customer terminal via the Internet places an order in the securities trading market via the ordering system in accordance with an instruction from the customer terminal.

  In an order with correction conditions represented by the current “W limit order”, a trigger 2 is provided for instructing the correction timing to the ordering system. Trigger 2 monitors a set market price (for example, stock price for a certain stock), time (for example, close 10 minutes before closing) or transaction result (for example, execution of another order), and orders to the ordering system when the correction condition is met Make a predetermined correction for the placed order.

  In the present invention, the trigger 1 is provided as a new trigger in order to determine the timing for placing an order with a correction condition, and at the same time to determine the correction condition set in the trigger 2. Trigger 1 also monitors the set market price (for example, the opening price for a stock), time (for example, the time when the market starts if the opening price is set) or trading results (for example, execution of other orders) If the order condition is satisfied, the order condition is determined to the ordering system to instruct the ordering with the correction condition, and the correction condition is determined as the correction condition of the trigger 2 and the condition is written.

  This eliminates the need for the investor to constantly monitor the execution status of other orders regarding the order timing of orders with correction conditions. In addition, it is possible to automatically set an order condition and a correction condition that can guarantee a certain profit confirmation and loss cut without setting the order condition and the correction condition to a predetermined value in advance.

  FIG. 2 shows a configuration of a trade order processing system according to the present invention. The buy / sell order processing system 100 includes an input processing unit 110, an order database 120, a trigger monitoring unit 130, a trigger database 140, an order processing unit 150, and a timer 160. The trigger monitoring unit 130 can refer to the market price database 200. It is configured. Note that the market price database 200 may be installed in the sales order processing system 100. The sales order processing system 100 is connected to the customer terminal 300 through a communication network such as the Internet.

  An investor who conducts online transactions inputs order details regarding an order with a correction condition including an order condition, an order condition, and a correction condition from the customer terminal 300. The order condition and the correction condition include, for example, “If order B is executed, sell 100 shares at the limit price of order B (X brand) + 50 yen, and the current price of X brand is the contract price of order B −20 If it becomes a yen, the limit price is corrected to the contracted price of order B minus 25 yen, and an uncertain variable such as “contract price of order B” is included in each condition.

  When the input processing unit 110 receives the input order, the content is written in the order database 120. Here, in the record relating to the order in the order database 120, the order condition is written in a state in which an unconfirmed variable (in the above example, “contract price of order B + 50 yen”) is included, and the correction condition is A record to the effect that the label is attached (for example, “ON” is recorded in the “trigger setting” field).

  Further, the input processing unit 110 extracts data relating to the ordering condition and the correction condition from the received order and writes the data in the trigger database 140. Of these, data relating to ordering conditions is written in the ordering trigger table 141, and data relating to correction conditions is written in the correction trigger table 142. Here, in the record related to the trigger in the correction trigger table 141, the correction condition and the correction content are undefined variables (in the above example, “order B contract price—20 yen” and “order B contract price—25 ")") Is included.

  The triggers written in the order trigger table 141 and the correction trigger table 142 are monitored by the trigger monitoring unit 130 as to whether or not a set condition is satisfied. An agent program having a monitoring function is set in the trigger monitoring unit 130, for example, the order database 120 constantly monitors the execution of other orders, the timer 160 monitors the market timing, and the market price database 200 constantly monitors the market price of a specific brand. is doing.

  First, the trigger monitoring unit 130 monitors the order trigger. When the condition defined in the order trigger is fulfilled (in the above example, “Order B is executed”), the order condition (in the above example “ The finalized value is written in the “contract price of order B + 50 yen”). At the same time, a record that the order condition has been fulfilled and the order can be placed (for example, “OFF” is recorded in the “trigger setting” field) is recorded.

  Further, when the condition defined in the order trigger is fulfilled (in the above example, “Order B is executed”), the correction trigger and the correction contents that have become uncertain variables in the correction trigger table 142 for the order. (In the above example, the “contract price of order B—20 yen” and “contract price of order B—25 yen”) are written in the final value.

  Next, the trigger monitoring unit 130 monitors the correction condition set in the correction trigger. When this condition is fulfilled (in the above example, the current value of the X issue will be a price corresponding to “contract price of order B—20 yen”), the order database 120 records that the order condition has been corrected (above In the example, the price corresponding to “contract price of order B + 50 yen” is corrected to the price corresponding to “contract price of order B−25 yen”, and the order correction unit 150 is instructed to correct the order, The ordered order is corrected.

  Next, specific examples of conditional orders by the system according to the present invention and effects thereof will be described with reference to FIGS. FIG. 5 and FIG. 7 show examples of orders that can be made by an order with correction conditions (so-called “W limit order”) currently provided by the present applicant as described above.

  In contrast to the example of FIG. 5, in the example of FIG. 6, a sell order is automatically placed simultaneously with the execution of the previous buy order by setting the execution of the previous buy order as an order trigger. Therefore, as shown in FIG. 5, it is possible to sell the product when it reaches 550 yen without missing the timing for determining profit.

  In this case, although the previous buy order is a limit order of 500 yen, the limit order means to buy at or below the limit price, so the contract price is not necessarily 500 yen, and is executed at 490 yen or 480 yen. There may be cases. Therefore, it is desirable that the reference price for setting the target profit margin and loss cut line is set at the stage when the previous buy order is executed. By adding the function to confirm these order conditions and correction conditions in the order trigger, if the above-mentioned base price is set as a variable, the order conditions and correction conditions can be defined in a form that matches the contract conditions. .

  Next, in the example of FIG. 8, in contrast to the example of FIG. 7, a sell order is automatically placed simultaneously with the execution of the previous buy order by setting the execution of the previous buy order as an order trigger. The same is true. The point here is that correction conditions are also set at the same time as ordering.

  Therefore, without missing the timing of the loss cut as shown in FIG. 7, in the example of FIG. 8, by surely capturing the stage of 480 yen for correcting the order for the loss cut, It is possible to prevent the loss width from expanding. Also in this case, the correction condition can be determined in a form that matches the contract condition, as in the example of FIG.

  Next, with reference to FIGS. 9 to 12, an example of setting a trigger for an order with a correction condition by the system currently provided by the applicant of the present application and the system according to the present invention will be described.

  FIG. 9 shows an example of an order that can be made by an order with correction conditions (so-called “W limit order”) currently provided by the applicant of the present application. If the current price of the sale and X brand is 480 yen, the order has been corrected with a correction condition “the limit price is corrected to 480 yen”. Here, a correction condition is set in the trigger that “the current value of the X issue is 480 yen”. This correction condition is monitored in the market price database, and when the X issue becomes 480 yen, the limit price is corrected to 475 yen. .

  On the other hand, as shown in FIG. 10, the order A using the system according to the present invention is “if the order B for X brand (buying 100 shares at the limit of 500 yen) is executed, ) If 100 shares are sold at the limit of the contract price + 50 yen, if the current price of the X stock is the contract price of order B-20 yen, the limit is corrected to the contract price of order B-25 yen. It is an order with correction conditions including variables.

  The trigger 1 is set with a condition “contract of order B” as an order trigger, and this condition is monitored with reference to the order history in the order database. In addition, a correction condition including an uncertain variable that “the current value of the X issue is the contract price of the order B—20 yen” is set as the correction trigger in the trigger 2, but the trigger condition is not fixed at this time. Therefore, the trigger is not monitored.

  In FIG. 11, since the X issue in the order B is executed at 500 yen, the order condition and the correction condition are “X issue sells 100 shares at the limit of 550 yen”, and “the current value of the X issue is 480 yen, The limit price has been corrected to 475 yen ”. Since the correction condition of the trigger 2 is also determined here, the correction condition that “the current value of the X issue is 480 yen” is monitored in the market price database.

  FIG. 12 shows a case where the correction condition is fulfilled. When the current price of the X brand reaches 480 yen, the limit price is changed to 485 yen, and the previous order is corrected to an order of “Selling 100 shares at the limit price of 475 yen for the X brand”.

  FIG. 13 shows an example of the configuration of the order database and trigger database according to the present invention. In the order database, there is a record for each commissioned order, and each record has an "order ID" that is a code that identifies the order, an "order condition" that describes the limit order conditions, and whether there is a trigger. A field such as “trigger setting” indicating “” is provided.

  In addition, the order trigger table of the trigger database includes a record for each order for which the order trigger is set, and each record describes an “order ID” that is a code for specifying the target order and an order condition. Fields such as “Order Price” and “Update Price” for updating uncertain conditions in other tables are provided. In addition, the correction trigger table of the trigger database includes a record for each order for which the correction trigger is set, and each record performs “order ID”, which is a code for specifying the target order, for correction. "Correction trigger" that describes the conditions of the "correction item" that indicates the item to be written when the correction trigger is confirmed, "correction content" that describes the content to correct the correction item, "trigger setting" that indicates whether there is a trigger And other fields are provided. Here, the “order ID” plays a role of associating the corresponding order when the conditions recorded as the respective triggers are fulfilled.

  The order trigger table and the correction trigger table are provided with different tables in the example of FIG. 13, but these tables are the same by providing a trigger code or the like so that the nature of the trigger can be distinguished. You may comprise so that it may record in this table.

  Here, if the order B for the X issue (buy 100 shares at the limit of 500 yen) is executed, 100 shares will be sold at the limit price of the order B (X issue) + 50 yen, and the current value of the X issue will be the order B If an order with a correction condition including an unconfirmed variable and an order condition “the limit price is corrected to the contract price of order B—25 yen when the price reaches −20 yen” and an unconfirmed variable is accepted, “Null + 50 yen” is recorded and “ON” is recorded in the trigger setting column since ordering conditions are added.

  In the order trigger table, “A01-000 (order B) contract price” is recorded in the order trigger field, and “A01-000 (order B) contract price” is recorded in the update price field. Furthermore, “null-20 yen” in the correction trigger column of the correction trigger table, “order condition” in the correction item column, “null-25 yen” in the correction content column, and monitoring of the correction trigger confirms the order. Therefore, “ON” is recorded in the trigger setting column.

  Here, when A01-000 (order B) set in the order trigger is executed, the trigger setting of A01-001 (order A) is set to “OFF”, and order A is ordered. The trigger setting in the correction trigger table is also set to “OFF”, and monitoring of the correction trigger starts. Further, for the contract price of order B shown in the renewal price column, the contract price of order B in the “null” part of “order condition” in the order database and “correction condition” and “correction contents” in the correction trigger table. And each amount is fixed as a constant.

  From this point, the monitoring of correction conditions starts for the correction trigger. Further, when the price set in the correction trigger is reached, the order condition in the order database is corrected to the price of “correction contents”, and the order placed in the market according to the order condition is corrected.

  Next, with reference to FIG. 14, a flowchart of the buying and selling order process according to the present invention will be described. In this example, an order trigger is set as the trigger 1 and a correction trigger is set as the trigger 2.

  First, the ordering condition of the trigger 1 is monitored (S01), and when the condition of the trigger 1 is not satisfied, the monitoring is continued (S02 to S01). On the other hand, when the condition of the trigger 1 is fulfilled (S02), the unconfirmed part of the trigger 2 and the order condition is updated (S03), and the order with the updated order condition is ordered (S04). The correction condition of the trigger 2 is monitored (S05).

  If the condition of trigger 2 is not fulfilled, monitoring is continued (S06 to S05). On the other hand, if the condition of trigger 2 is fulfilled (S06), the condition of the ordered order is corrected according to the condition determined in S03 (S07).

  FIG. 15 and FIG. 16 show a specific example of a trade order processing flow according to the present invention. FIG. 15 shows an example of placing an order with correction conditions based on the execution of the previous order, and FIG. 16 shows an example of placing an order with correction conditions based on the close of the day, which is corrected based on the contract price and opening price of the previous order. Conditions are set.

  Fig. 15 shows, “If order B for X issue (buy 100 shares at limit price of 500 yen) is executed, sell 100 shares at the limit price of order B (X issue) + 50 yen, and the current value of X issue will be This is an example of the order A with a correction condition that “the limit price is corrected to the contract price of the order B—25 yen when the contract price of the order B is −20 yen”. An order trigger “Order B is executed” is set in the trigger 1, and the trigger monitoring unit monitors the execution of the order B of the X brand. When order B is executed at a buy price of 500 yen, the contract price is also determined, and the order conditions and correction conditions for order A are also determined. Here, a selling order is placed under the conditions determined for order A.

  Next, in the trigger 2, the correction trigger that was set as “the current price of the X brand is the contracted price of the order B—20 yen” is confirmed as “the current price of the X brand is 480 yen”, and the trigger setting is turned OFF. Then, the monitoring unit starts monitoring the market price of the X brand. When the current value of the X issue reaches 480 yen, the order condition in the order database is corrected, and the original order is corrected from the order processing unit to the order of “sell 100 shares at the limit of 475 yen for the X issue”.

  FIG. 16 shows an order C with a correction condition that “Y stocks are sold at 100 shares at the opening price +50 yen limit, and if the current price of the Y stock is the opening price −20 yen, the limit price is corrected to the opening price −25 yen”. It is an example. The trigger 1 is set to an order trigger called “Y price starting price”, and the trigger monitoring unit monitors the Y brand donation. When the Y brand closes at 500 yen, the opening price is fixed, and the order condition and the correction condition for the order C are also fixed. Here, a selling order is placed under the conditions determined for order C.

  Next, in Trigger 2, the correction trigger that was set as “Y brand current value is the starting price of −20 yen” is confirmed as “Y brand current value is 480 yen”, and the trigger setting is turned OFF and monitored. Department starts monitoring the market price of Y brand. When the current value of the Y issue reaches 480 yen, the order condition in the order database is corrected, and the original order is corrected from the order processing unit to an order of “Y issue sells 100 shares at a limit of 475 yen”.

  In addition to the examples of FIGS. 15 and 16, various settings can be made for the trigger 1 and the trigger 2. For example, Trigger 1 monitors the balance of assets held by a customer who has placed an order. When the unrealized gain of a certain stock reaches a certain value, it places a selling order with a certain margin, and conversely a certain loss. It is also possible to make a setting to correct the order of loss cut when this occurs.
