  In recent years, algorithmic trading has become widespread. A computer (algorithm trading system) on which an algorithm trading program is executed monitors in real time changes in the price, quality, board shape, related indices and technical indicators of the target stock in the market, and buys and sells based on the monitoring results. Determine the timing and quantity of the order and repeat the order automatically.

  Before such an algorithmic trading system actually operates, it must be verified (performance evaluation) whether it works properly, but it is not possible to repeat the verification of software operation by placing an order for buying and selling to the actual market. Costs and risks are too high to be practically impossible.

  Therefore, a pseudo (virtual) market that can be used for performance evaluation of algorithmic trading systems is required. When a market is realized by simulation, it is important to be able to perform a simulation closer to the actual market. For that purpose, it is necessary to consider the simulation of the transition of the market impact that occurs when an order from the algorithm trading system is executed.

  With regard to this pseudo market, for example, Patent Document 1 discloses a technique for realizing a market impact simulation. In Patent Document 1, an attenuation coefficient is provided as a parameter relating to market impact.

And a tick transition time extracting process for extracting the time and the down tick time. In one aspect, the processor performs a parameter calculation process for calculating a market impact attenuation coefficient by counting up tick time and down tick time and statistically processing the up tick time and the down tick time in at least a specified period. To do.

  The CPU 11 performs various processes by executing a program stored in the memory 12. The memory 12 temporarily stores programs executed by the CPU 11 and information required by the CPU 11. For example, the memory 12 stores a program and information read from the HDD 13.

  The HDD 13 stores various programs and various information. For example, the HDD 13 stores the original tick data 21, a disassembled order file 232, a simulation parameter 22, and a result file 239 described later.

  The communication control device 14 is connected to the algorithm trading system via a network 19 such as a LAN or the Internet. The algorithm trading system is a computer that includes a CPU, a memory, and an interface and executes an algorithm trading program.

The external input / output device 18 outputs information (for example, print output, voice output, etc.) instructed by the CPU 11.

<Functional configuration of the entire system>
FIG. 2 is a block diagram showing a functional configuration of the entire system configured by the execution simulation system 1 including the market impact attenuation coefficient calculation system 6 and the algorithm trading system 24 according to the embodiment of the present invention. The contract simulation system 1 to which the market impact attenuation coefficient calculation system 6 is applied generates and reproduces orders that have been in the past, and is a type of contract simulation that simulates the generation and attenuation of market impacts due to the execution of orders placed from an algorithm trading program. System.

  The contract simulation system 1 stores the tick original data 21 in advance. The original tick data 21 is a history of tick data in the actual market (past tick data). Tick data is information relating to price movements of securities at a certain time. Details of the original tick data 21 and tick data will be described with reference to FIG.

  First, the algorithm trading system 24 logs on to the contract simulation system 1 in advance. Thereafter, when the execution simulation system 1 receives a start command including a start parameter (not shown), the contract simulation system 1 starts the simulation. The activation parameter is information including a brand code, a target date, a start time, and an end time. Specifically, the contract simulation system 1 is identified by the brand code included in the start parameter from the start time included in the start parameter to the end time included in the start parameter in the target date included in the start parameter. A simulation is performed when the stock trading (securities) of a brand is traded by an algorithm trading system. In the present embodiment, the stock is described as an example of the securities to be traded. However, the technology according to the present invention is not limited to stock trading, and can be applied to currency trading, bond trading, and the like.

  First, the contract simulation system 1 executes pre-processing 231 such as order disassembly based on the original tick data 21 and activation parameters. Details of the order disassembly pre-processing 231 executed by the contract simulation system 1 will be described in detail with reference to FIG.

  The contract simulation system 1 creates a post-decomposition order file 232 by executing pre-processing such as order decomposition for decomposing the original data 21 into individual orders. The post-decomposition order file 232 shows an order history for the stock of the brand identified by the brand code included in the activation parameter. However, the post-decomposition order file 232 does not indicate an order history in the actual market but indicates a virtual order history estimated by the execution of the pre-processing 231 such as the order disassembly by the contract simulation system 1. For example, one virtual order is a collection of a plurality of orders that are generated at the same time in the actual market. Even if the virtual order is a market order, there is a limit order in the actual market.

  Further, the contract simulation system 1 calculates the market impact attenuation coefficient from the original data 21 using the market impact attenuation coefficient calculation system 6 and stores the calculated attenuation coefficient as the simulation parameter 22. Details of the processing by the market impact attenuation coefficient calculation system 6 will be described later with reference to FIG.

  Next, the contract simulation system 1 includes an order board registration process (tick order board registration process) 233, a tick data creation and transmission process 235, an algo order logic check process 236, and an algo order board registration in the execution simulation core unit 23. Processing 237 and execution simulation processing 238 are executed.

  In the order board registration process 233, the contract simulation system 1 creates or updates a work board (simulation work board) 234 that is a copy of an order for each brand in the simulation, based on the created post-disassembly order file 232. The work board 234 is a logical board that indicates the order status of the stock of the brand identified by the brand code included in the above-described activation parameter, and is stored in the memory 12. Therefore, the work board 234 indicates the number of shares in the sell order and the number of shares in the buy order for each price. More specifically, the contract simulation system 1 registers a virtual order (tick order) included in the post-disassembly order file 232 in the simulation work board 234 in time series. At this time, the contract simulation system 1 registers the tick order in the simulation work board 234 in consideration of the market impact indicating the magnitude of the influence by the order (algo order) from the algorithm trading system 24. For example, the contract simulation system 1 calculates the market impact based on the simulation parameter 22.

  Further, the contract simulation system 1 performs a tick data creation / transmission process (a process of restoring and transmitting a work plate change to tick data: also referred to as a tick restoration process) 235. In the tick data creation / transmission process 235, the contract simulation system 1 monitors changes in the simulation work plate 234. Whenever there is a change in the simulation work board 234, the contract simulation system 1 extracts change information from the simulation work board 234. Then, the contract simulation system 1 creates tick data in the simulation based on the extracted change information. The tick data in the simulation is the same as that included in the original tick data 21 before the algo order is received. On the other hand, after receiving the algo order, the tick data in the simulation becomes price movement information corresponding to both the tick order and the algo order. In the tick data creation and transmission process 235, the contract simulation system 1 transmits the tick data in the created simulation to the algorithm trading system 24 as market price information. The algorithm trading system 24 receives tick data from the contract simulation system 1. Then, the algorithm trading system 24 analyzes the received tick data. Then, the algorithm trading system 24 determines the order content of the brand based on the analysis result, and transmits the order of the determined content to the contract simulation system 1.

  The contract simulation system 1 receives an order from the algorithm trading system 24. Further, the execution simulation system 1 logically checks the validity of the brand and price of the algo order transmitted from the algorithm trading system (part of the algo order logical check processing 236).

  If the Argo order is logically incorrect, the contract simulation system 1 creates an order acceptance error notification. Next, the contract simulation system 1 transmits the created order reception error notification to the algorithm trading system 24.

  On the other hand, if the algo order is logically correct, the contract simulation system 1 creates an order acceptance notification including the unique identifier of the algo order. Moreover, the contract simulation system 1 transmits the created order reception notification to the algorithm trading system.

  In addition, in the board registration 237 of the algo order, the contract simulation system 1 determines whether or not the received algo order can be reflected on the work board 234. For example, when the algo order is a correction order or a cancellation order, the contract simulation system 1 determines whether the order (buy order or sell order) requested to be corrected or canceled by the algo order remains on the simulation work board 234. Determine whether or not.

  If the algo order cannot be reflected on the work board 234, the execution simulation system 1 creates an execution error notification including the identifier of the algo order. Next, the contract simulation system 1 transmits the created execution error notification to the algorithm trading system.

  On the other hand, when the algo order can be reflected on the work board 234, the contract simulation system 1 registers the received algo order on the simulation work board 234 in time series (algo order board registration processing 237).

  In the execution simulation process 238, the execution simulation system 1 performs a simulation for executing an order registered in the simulation work board 234.

  The contract simulation system 1 creates tick data in the simulation based on the simulation result. The contract simulation system 1 stores the created tick data in the result file 239. Therefore, the result file 239 becomes a history of tick data created in the simulation.

  In addition, when the Argo order is executed in the execution of the execution of the execution simulation process 238, the execution simulation system 1 creates an execution notice including the execution price and the execution amount.

  Next, the contract simulation system 1 transmits the created contract notification to the algorithm trading system 24.

  Further, the contract simulation system 1 stores the information included in the created contract notification in the result file 239 as information related to the execution of the Argo order.

  Thereafter, when the simulation by the contract simulation system 1 ends, the algorithm trading system 24 logs out from the contract simulation system 1.

<Rick raw data>
FIG. 3 is a diagram illustrating the configuration of the tick original data 21.

  The contract simulation system 1 stores the original tick data 21 for each transaction day in the actual market. Therefore, in the original tick data 21, the tick data 210 on a specific transaction date is arranged in time series. The original tick data 21 includes the history of the tick data 210 in the actual market for each brand.

  The tick data 210 in the actual market includes a transaction date 310, a time 311, a stock code 312, a record serial number 313, a contract price (current price) 314, a contract price 315, a bid price 316, and a bid price. 317, an offer price 318, and an offer price 319 are included as configuration information.

  The transaction date 310 indicates the date on which the tick data 210 was created. Time 311 indicates the time when the tick data 210 is created. That is, the transaction date 310 and the time 311 indicate when the tick data 210 is price movement information at the actual market.

  The brand code 312 is a unique identifier of the brand corresponding to the tick data 210. The record serial number 313 is a serial number for identifying the tick data 210.

  The contract price (current value) 314 is a stock price at the time when the tick data 210 is created. Specifically, the contract price (current price) 314 indicates the stock price of the brand identified by the brand code 312 on the transaction date 310 and the time 311.

  The contract height 315 indicates the number of shares that the stock of the brand identified by the brand code 6509 is contracted between the time when the previous tick data 210 is created and the time when the current tick data 210 is created.

  The sell price 316 is a price (a quote price) specified in the sell order. It should be noted that the bid price 316 included in the tick data 210 has changed in the bid price between the time when the previous tick data 210 was created and the time when the current tick data 210 was created (a new sell order entered). It is an indicative price.

  The bid price 318 indicates the total number of shares in the sell order at the bid price 316. Note that a plurality of the bid price 316 and the bid price 318 may be included in the tick data 210. In this case, one selling price 316 corresponds to one selling price 318. The bid price 318 indicates the total number of shares in the sell order at the bid price 316 corresponding to the bid price 318.

  The bid price 317 is a price specified in the purchase order. Note that the bid price 317 included in the tick data 210 has changed in the bid price from the time when the previous tick data 210 was created to the time when the current tick data 210 was created (a new buy order entered). It is an indicative price.

  The bid price 319 indicates the total number of shares in the buy order at the bid price 317. A plurality of bid price 317 and bid price 319 may be included in tick data 210. In this case, one bid price 317 corresponds to one bid price 319. The bid price 319 indicates the total number of shares in the buy order at the bid price 317 corresponding to the bid price 319.

<Details of pre-processing 231 such as order disassembly>
FIG. 4 is a flowchart for explaining the contents of the order disassembly pre-processing 231 executed by the contract simulation system 1 according to the embodiment of the present invention.

(I) S401
First, the contract simulation system 1 uses the stock code included in the start parameter from the start time included in the start parameter to the end time included in the start parameter for the target date included in the start parameter (not shown). All tick data 210 relating to the brand to be identified is selected from the original tick data 21.

  Specifically, the contract simulation system 1 selects, from the tick original data 21, tick data 210 in which the target date included in the activation parameter matches the transaction date 310 of the tick data 210. Next, the contract simulation system 1 selects, from the selected tick data 210, the tick data 210 corresponding to the time 311 of the tick data 210 from the start time to the end time included in the activation parameter. Then, the contract simulation system 1 selects, from the selected tick data 210, the tick data 210 in which the brand code included in the activation parameter matches the brand code 312 of the tick data 210.

  Next, the contract simulation system 1 acquires the selected tick data 210 one by one in order from the oldest created time (S401). Specifically, the contract simulation system 1 acquires the selected tick data 210 in order from the smallest record sequence number 313 of the tick data 210. Alternatively, the contract simulation system 1 acquires the selected tick data 210 in order from the oldest time 311 of the tick data 210.

(Ii) S402
The contract simulation system 1 creates a new work plate 234 (current work plate 234) based on the acquired tick data 210 and the work plate 234 created in S402 in the previous process (previous work plate 234) ( S402).

  Specifically, the contract simulation system 1 selects, from the previous work plate 234, a record in which the sale price 316 of the acquired tick data 210 matches the previous work plate 234. Next, the contract simulation system 1 stores the sales volume 318 of the acquired tick data 210 in the sales volume of the selected record. Then, the contract simulation system 1 selects, from the previous work plate 234, a record in which the bid price 317 of the acquired tick data 210 and the previous work plate 234 match. Further, the contract simulation system 1 stores the bid price 319 of the acquired tick data 210 in the bid price of the selected record. As a result, the contract simulation system 1 creates the work plate 234 this time.

(Iii) S403
The contract simulation system 1 determines whether or not an order has been executed between the time corresponding to the previous work plate 234 and the time corresponding to the current work plate 234 (S403).

  Specifically, the contract simulation system 1 determines whether “0” is stored in the contract constant amount 315 of the acquired tick data 210. When “0” is stored in the contract amount 315, the contract simulation system 1 determines that an order has not been contracted between the time corresponding to the previous work plate 234 and the time corresponding to the current work plate 234. To do. In this case, the contract simulation system 1 shifts the processing to S405.

  On the other hand, when a value other than “0” is stored in the contract amount 315, the contract simulation system 1 executes the contract between the time corresponding to the previous work plate 234 and the time corresponding to the current work plate 234. It is determined that In this case, the contract simulation system 1 creates a work board 234 immediately before the order is executed (work board 234 immediately before execution) based on the acquired tick data 210 and the current work board 234.

  Specifically, the contract simulation system 1 selects, from the current work board 234, a record in which the contract value (current value) 314 of the acquired tick data 210 matches the quote value of the current work board 234. Next, the contract simulation system 1 adds the approximate constant amount 315 of the acquired tick data 210 to one of the sales volume or the sales volume of the selected record. The contract simulation system 1 compares the previous work plate 234 and the current work plate 234 to determine whether to add the acquired constant quantity 315 of the tick data 210 to the sell price or the buy price. To do.

(Iv) S404
The contract simulation system 1 selects a record indicating information related to the market order from the current work plate 234. Next, the contract simulation system 1 adds the approximate constant amount 315 of the acquired tick data 210 to the other of the sales volume and the sales volume of the selected record. As a result, the contract simulation system 1 creates the work plate 234 immediately before the contract (S404). The contract simulation system 1 creates the work plate 234 immediately before the contract, assuming that the order entered immediately before the contract is a market order. Therefore, the order placed immediately before the contract may actually be a limit order.

(V) S405 and S406
The contract simulation system 1 compares the previous work plate 234 with the current work plate 234 or the previous work plate 234 (S405), estimates a virtual order (tick order), and disassembles the estimated tick order into an order file. It is stored in H.232 (S406).

  When the contract is not made between the time corresponding to the previous work plate 234 and the time corresponding to the current work plate 234, the contract simulation system 1 compares the previous work plate 234 with the current work plate 234. Therefore, the contract simulation system 1 stores both the previous work plate 234 and the current work plate 234.

  On the other hand, when the contract is made between the time corresponding to the previous work plate 234 and the time corresponding to the current work plate 234, the contract simulation system 1 compares the previous work plate 234 with the work plate 234 immediately before the contract. Therefore, the contract simulation system 1 stores both the previous work plate 234 and the work plate 234 immediately before the contract.

  Here, the process of comparing the previous work plate 234 and the current work plate 234 will be described, but the process of comparing the previous work plate 234 and the work plate 234 immediately before the contract is the same.

  The contract simulation system 1 selects in order from both the previous work plate 234 and the current work plate 234 a record in which the previous work plate 234 and the current work plate 234 have a matching value. The contract simulation system 1 performs the following processing for each selected record.

  The contract simulation system 1 determines whether or not the sales volume of the record selected from the previous work board 234 matches the sales volume of the record selected from the current work board 234. If the two sell price quantities match, a new sell order with the quote price of the record selected from the previous work board 234 or the current work board 234 has not occurred. Therefore, in this case, the contract simulation system 1 does not update the post-decomposition order file 232. On the other hand, if the two sell price quantities do not match, a sell order is newly generated at the quote price of the record selected from the previous work board 234 or the current work board 234. Therefore, the contract simulation system 1 generates a sales order (tick order). Specifically, the contract simulation system 1 calculates the number of shares in the sales order by subtracting the sales volume of the record selected from the previous work board 234 from the sales volume of the record selected from the current work board 234. . Then, the contract simulation system 1 generates a sell order for the calculated number of shares at the quote price of the selected record.

  Then, the contract simulation system 1 stores the generated sales order information in the disassembled order file 232. Specifically, the contract simulation system 1 adds a new record to the post-decomposition order file 232.

  Next, the contract simulation system 1 holds the time 311 of the tick data 210 acquired in S401 as the time of the new record.

  Further, the contract simulation system 1 determines whether or not the calculated number of shares in the sell order is a positive value. When the number of shares in the sell order is a positive value, the contract simulation system 1 holds information indicating a sell order as a new record type. On the other hand, when the calculated number of shares of the sell order is a negative value, the contract simulation system 1 holds information indicating that it is a sell correction order or information indicating that it is a cancel order as a new record type. To do.

  Next, the contract simulation system 1 holds the quotation value of the record selected from the previous work board 234 or the current work board 234 as a new record value. Further, the contract simulation system 1 holds the calculated number of shares in the selling order as the quantity of a new record.

  As a result, the contract simulation system 1 stores the generated information regarding the sales order in the disassembled order file 232.

  Further, the contract simulation system 1 determines whether or not the buy price of the record selected from the previous work board 234 matches the buy price of the record selected from the current work board 234. When the two bid price matches, no new buy order has been generated at the quote price of the record selected from the previous work board 234 or the current work board 234. Therefore, the contract simulation system 1 does not update the post-decomposition order file 232. On the other hand, if the two buy price quantities do not match, a new purchase order is generated at the quote price of the record selected from the previous work board 234 or the current work board 234. Therefore, the contract simulation system 1 generates a buy order (tick order). Specifically, the contract simulation system 1 calculates the number of shares of the buy order by subtracting the bid price of the record selected from the previous work board 234 from the bid price of the record selected from the current work board 234. . Then, the contract simulation system 1 generates a buy order for the calculated number of shares at the quote price of the selected record.

  Subsequently, the contract simulation system 1 stores information on the generated purchase order in the disassembled order file 232. Specifically, the contract simulation system 1 adds a new record to the post-decomposition order file 232. The contract simulation system 1 stores the time 311 of the tick data 210 acquired in S401 as the time of the new record.

  Next, the contract simulation system 1 determines whether or not the calculated number of shares of the buy order is a positive value. When the number of shares in the buy order is a positive value, the contract simulation system 1 holds information indicating a buy order as a new record type. On the other hand, when the calculated number of shares of the buy order is a negative value, the execution simulation system 1 holds information indicating a purchase correction order or information indicating a purchase cancellation order as a new record type. To do.

  Further, the contract simulation system 1 holds the quotation value of the record selected from the previous work plate 234 or the current work plate 234 as the value of the new record. Further, the contract simulation system 1 holds the calculated number of shares in the purchase order as the number of new records.

  As described above, the contract simulation system 1 stores the information related to the generated purchase order in the disassembled order file 232.

(Vii) S407
The contract simulation system 1 determines whether or not all of the selected tick data 210 has been acquired (S407).

  If even one of the selected tick data 210 has not been acquired, the contract simulation system 1 returns the process to S401 and repeats S401 to S406. On the other hand, when all of the selected tick data 210 are acquired, the contract simulation system 1 ends the pre-processing 231 such as order disassembly.

<Market impact attenuation coefficient calculation processing>
(I) Basic data for calculating market impact attenuation coefficient FIG. 5 is a graph showing basic data extracted from the tick original data 21 for calculating the market impact attenuation coefficient.

  The basic data corresponds to the time of the up tick period and the time of the down tick period, and the basic data is extracted according to the front and back fields by brand. In addition, as shown in FIG. 5, the uptick period 51 is a period in which the contract price greater than or equal to the previous contract value is continuous, and the down tick period 52 is the period in which the contract value less than or equal to the previous contract value is continued. It is. A specific example is shown in FIG.

  FIG. 6 is a diagram illustrating a data configuration example of the time of the up tick period and the time of the down tick period. The uptick period is the time from the contract time when the contract price was greater than or equal to the previous contract price to the contract time before the contract price that was less than the previous contract price (reversed in the downtick direction). That is. In addition, the down tick period is from the time when the contract became the contract price less than or equal to the previous contract to the contract before the contract before the contract that exceeded the previous contract (reversed in the uptick direction). That is.

  Reversing in the down tick direction after the up tick period (and reversing in the up tick direction after the down tick period) means that the spread (difference between the best selling price and the best buying price) temporarily increased due to market impact This phenomenon is a result of shrinking while attracting the buying and selling needs that were in line with this, and it can be considered that the temporary impact decay has converged. Therefore, the uptick period of the stock is used as the basic data for calculating the damping coefficient when the purchase algorithm is executed in the execution simulation system, and the downtick period is executed in the execution simulation system. By calculating the market impact attenuation coefficient parameter as basic data for calculating the attenuation coefficient at the time, the transition of the market impact in the actual market can be reflected in the execution simulation system.

(Iii) Detailed Contents of Processing FIG. 7 is a flowchart for explaining the contents of market impact attenuation coefficient calculation processing. The market impact attenuation coefficient calculation process is roughly divided into three processes: a previous execution / current execution acquisition process 61, an uptick time / downtick time extraction process 62, and an aggregation process / coefficient calculation process 63. The previous execution / current execution acquisition processing 61 sequentially inputs the execution of tick data records from the past actual market price information 21 and acquires the previous execution information and the current execution information (the execution value of the execution in FIG. 6). Process to get each).

  The uptick time / downtick time extraction process 62 acquires the start and start time / continuation / end / end time of the uptick period, and the start / start time / continuation / end / end time of the downtick period. , A process for extracting the down tick time (a process for extracting the time of the up tick period and the down tick period in FIG. 6). In the extraction process 62, since the latest tendency of the uptick time and the downtick time is extracted, the extraction period such as the last one month is designated by the user.

  The aggregation process / coefficient calculation process 63 is a process (see FIG. 8) for aggregating information of the uptick period and the downtick period and calculating a market impact attenuation coefficient from the aggregated value. The market impact attenuation coefficient calculation system 6 receives as input the history of tick data generated for a certain brand in the actual market in the past and the market price information original data 21 which is basic information of the brand. The market price information original data (tick original data) 21 includes tick data (see FIG. 3).

(A) Previous execution / current execution acquisition process 61
First, the market impact attenuation coefficient calculation system 6 sets each of the previous contract value, the current contract value, and the UpDown code to “0” and initializes them (S701).

  The market impact attenuation coefficient calculation system 6 rewrites the previous contract value with the current contract value (S702). In the initial stage, since the previous contract value and the current contract value are both “0”, the previous contract value is set to “0”.

  The market impact attenuation coefficient calculation system 6 reads the market price information original data (tick original data) 21 in order to extract basic data for calculating the market impact attenuation coefficient, and acquires tick data (S703). In the extraction of basic data, data that differs significantly from the normal day may be extracted on special days related to corporate actions such as stock splits, capital increases, mergers, etc., so exclude special days. You can also.

  The market impact attenuation coefficient calculation system 6 determines whether the acquired tick data is a contracted data (whether it is a contract or a sign) (S704). If the acquired data is contract data, the process proceeds to S705. If the acquired data is indicative data, the process returns to S703, and the processes of S703 and S704 are repeated until new tick data is acquired as execution data.

  The market impact attenuation coefficient calculation system 6 determines whether or not the previous contract value was “0” (S705). When the previous execution value is “0”, the process proceeds to S706, and when it is not “0”, the process proceeds to S708.

  In S706, the market impact attenuation coefficient calculation system 6 replaces the previous contract value with the current contract value specified in S704.

  Then, the market impact attenuation coefficient calculation system 6 sets the time (current contract time) contracted to the current contract value as the UpDown start time (S707), and shifts the process to S703.

(B) Uptick time / Downtick time extraction processing 62
The market impact attenuation coefficient calculation system 6 compares the previous contract value with the current contract value (S708). If the previous contract value <the current contract value, the process proceeds to S709. If the previous contract value> the current contract value, the process proceeds to S714. If the previous contract value = the current contract value, the process proceeds to S719.

  In S709, the market impact attenuation coefficient calculation system 6 determines whether the previous UpDown code is D (Down), 0, or U (Up). If the previous UpDown code is D, the process proceeds to S710. If the previous UpDown code is 0, the process proceeds to S713. If the previous UpDown code is U, the process proceeds to S719.

  In S710, the market impact attenuation coefficient calculation system 6 sets the time determined by (previous execution time−UpDown start time) as the down tick time and holds it in the up tick time / down tick time data store 621 (temporarily. Store). In other words, in this case (when the current contract value is larger than the previous contract value and the previous UpDown code is D), it means that the down tick has changed to the up tick, so the down tick time until then is It is necessary to keep it.

  Then, the market impact attenuation coefficient calculation system 6 changes the UpDown code from D to U (S711), and sets the UpDown start time to the current contract time (S712). Thereafter, the process proceeds to S719.

  When the previous UpDown code is 0 (S709), the market impact attenuation coefficient calculation system 6 changes the UpDown code from 0 to U in S713. Thereafter, the process proceeds to S719.

  On the other hand, if it is determined in S708 that the previous contract value> the current contract value, in S714, the market impact attenuation coefficient calculation system 6 determines whether the previous UpDown code is D (Down), 0, or U (Up ) If the previous UpDown code is U, the process proceeds to S715. If the previous UpDown code is 0, the process proceeds to S718. If the previous UpDown code is D, the process proceeds to S719.

  In S715, the market impact attenuation coefficient calculation system 6 sets the time determined by (previous execution time−UpDown start time) as the uptick time and holds it in the uptick time / downtick time data store 621 (temporarily. Store). In other words, in this case (when the current contract value is smaller than the previous contract value and the previous UpDown code is U), it means that the up-tick has changed to the down-tick. It is necessary to keep it.

  Then, the market impact attenuation coefficient calculation system 6 changes the UpDown code from U to D (S716), and sets the UpDown start time to the current contract time (S717). Thereafter, the process proceeds to S719.

  When the previous UpDown code is 0 (S714), in S718, the market impact attenuation coefficient calculation system 6 changes the UpDown code from 0 to D. Thereafter, the process proceeds to S719.

(C) Total process / coefficient calculation process 63
In S719, the market impact attenuation coefficient calculation system 6 determines whether all data (uptick period and downtick period data) in the specified period of the brand specified by the user has been acquired. If all the data has been acquired, the process proceeds to S720, and if not yet acquired, the process proceeds to S702.

  In S720, the market impact attenuation coefficient calculation system 6 reads the up tick time / down tick time 621 temporarily stored when the up tick time / down tick time extraction process 62 is executed, and performs the specified period. The data of uptick time / downtick time (FIG. 6) is aggregated to calculate the market impact attenuation coefficient and stored in the simulation parameter 22. The specific calculation of the market impact attenuation coefficient will be described later (see FIG. 8).

<Details of market impact attenuation coefficient parameter calculation>
FIG. 8 is a diagram for explaining specific contents of market impact attenuation coefficient parameter calculation. The market impact attenuation coefficient parameter is the minimum value, maximum value, average value, median value, and minimum value of the downtick time so that the execution simulation system 1 can express the market impact transition in the actual market more finely. Output the aggregated data 801 for the maximum value, the average value, and the median for each field division (for example, display the aggregated data 801 on the display 17).

  The user may appropriately set the market impact attenuation coefficient parameter with reference to the aggregated data 801 (the user may select an appropriate value from each of the presented statistical data, or each of the presented statistics The user may appropriately calculate from the data (the average value or the median value may be calculated), and the market impact attenuation coefficient calculation system 6 automatically generates the market impact attenuation coefficient parameter based on the aggregated data 801. Also good.

  In the former case, the market impact attenuation coefficient calculation system 6 receives the market impact attenuation coefficient determined by the user based on the aggregated data 801 and uses it as a parameter used in the contract simulation.

  In the latter case, the market impact attenuation coefficient parameter is calculated based on the aggregation end date designated by the user and the data of the aggregation period (for example, the past one month, three months, six months, etc.) starting from the end date. . For example, for all uptick times and downtick times in a specified period, the average value or median value of the data is used as a parameter. In addition, all the data of the previous field in the specified period (up tick time and down tick time) are targeted, and the average value or median value in the data is used as the parameter for the front field. The average value or median value in the data may be used as a parameter for the subsequent market. Further, an average value or median value in the data of all uptick times in the specified period may be used as an uptick parameter, and an average value or median value in the data of all downtick times in the specified period may be used as a downtic parameter. With respect to these up-tick parameters and down-tick parameters, parameters for the front field and the rear field may be generated. Further, the user may be able to select whether to adopt an average value or a median value as a parameter.

  The market impact attenuation coefficient parameter calculated as described above is an element that determines the time required to attenuate the temporary impact (impact that occurs temporarily and disappears with the passage of time) in the market impact curve in the execution simulation system 1. Become. FIG. 9 shows an example of a market impact curve for a purchase contract, and FIG. 10 shows an example of a market impact curve for a sell contract. That is, as shown in FIGS. 9 and 10, the market impact attenuation coefficient parameter 8 is set to “market value immediately before a temporary rise or fall ± permanent impact (from the time when the market value rises or falls due to temporary impact ( It is the time to return to the value represented by “the impact that remains as a permanent price change)”.

  In FIG. 8, total data 801 obtained by performing total processing on all data included in the original data 21 is shown. However, the total data is only displayed for the total period specified by the user. 801 may be acquired. That is, the market impact attenuation coefficient parameter can be obtained if at least aggregate data for a specified period is obtained.

<Contract simulation>
FIG. 11 is a flowchart for explaining processing of the contract simulation system 1 to which the market impact attenuation coefficient calculation system 6 is applied. The contract simulation system 1 uses the market impact attenuation coefficient, which is the output of the market impact attenuation coefficient calculation system 6, as a simulation parameter.

  The contract simulation system 1 registers an algo order or a tick order in the work plate 234 (simulation work plate 234) indicating the price movement in the simulation according to the time series. The contract simulation system 1 executes the work board registration / contract simulation process each time an attempt is made to register an algo order or a tick order in the simulation work board 234.

(I) S1101
First, the contract simulation system 1 determines whether the order to be registered in the simulation work board 234 is an algo order or a tick order (S1101). When a tick order is to be registered in the simulation work board 234, the contract simulation system 1 calculates the market impact when the tick order is generated based on the simulation parameter 22.

  FIG. 12 is an explanatory diagram of the market impact ΔP calculated by the contract simulation system 1 according to the embodiment of this invention. The market impact ΔP is a value indicating the magnitude of the influence due to the execution of the Argo order. Therefore, the market impact ΔP preferably decays exponentially with the passage of time from the execution time t0 of the Argo order. For example, the market impact ΔP attenuates according to the attenuation coefficient T. Further, it is preferable that the market impact ΔP has a fixed ratio (permanent impact ratio P) of the initial impact P0 permanently. The initial impact P0 is a market impact at the execution time t0 of the algo order, and is calculated in S1107 of the work board registration / contract simulation process. In other words, t0 is the time of occurrence of the initial impact P0. The attenuation coefficient T and the permanent impact ratio P are included in the simulation parameter 22. For example, the contract simulation system 1 uses Equation 1 to calculate the market impact ΔP (t) at the tick order generation time t.

[Formula 1]
ΔP (t) = (1−P) · P0 · exp (− (t−t0) / T / 5) + P · P0

(Ii) S1102
When the market simulation is calculated, the contract simulation system 1 rounds the calculated market impact to an integer. Then, the contract simulation system 1 reflects the integer market impact on the price specified in the tick order to be registered (S1102). Specifically, the contract simulation system 1 determines whether the Argo order that generated the calculated market impact is a sell order or a buy order.

  When the Argo order is a sell order, the contract simulation system 1 calculates the registration price by subtracting the integer market impact from the price specified in the tick order to be registered.

  On the other hand, when the Argo order is a buy order, the contract simulation system 1 calculates the registration price by adding the integer market impact to the price specified in the tick order to be registered.

(Iii) S1104 (in the case of S1102 → S1104)
The contract simulation system 1 registers the tick order in the simulation work board 234 based on the calculated registration price (S1104). Specifically, when the tick order is a sell order, the contract simulation system 1 selects, from the simulation work board 234, a record in which the calculated registered price matches the quote price of the simulation work board 234. Next, the contract simulation system 1 adds the number of shares specified in the tick order to the sales volume of the selected record.

  On the other hand, when the tick order is a sales correction order or a sales cancellation order, the contract simulation system 1 selects, from the simulation work board 234, a record in which the calculated registered price matches the quotation price of the simulation work board 234. Then, the contract simulation system 1 subtracts the number of shares specified in the tick order from the sales volume of the selected record.

  On the other hand, when the tick order is a buy order, the contract simulation system 1 selects, from the simulation work board 234, a record in which the calculated registered price matches the quotation price of the simulation work board 234. Next, the contract simulation system 1 adds the number of shares specified in the tick order to the buy price of the selected record.

  On the other hand, when the tick order is a purchase correction order or a purchase cancellation order, the contract simulation system 1 selects from the simulation work board 234 a record in which the calculated registered price matches the quotation price of the simulation work board 234. Next, the contract simulation system 1 subtracts the number of shares specified in the tick order from the bid price of the selected record.

  As described above, the contract simulation system 1 registers the tick order in the simulation work board 234 based on the calculated registration price. If the Argo order has not been registered in the simulation work board 234 so far, the contract simulation system 1 uses the price specified in the tick order as the registered price. That is, the contract simulation system 1 registers the tick order in the simulation work board 234 without considering the market impact (as usual).

(Iv) S1103
On the other hand, when an algo order is to be registered on the simulation work board 234 (when it is determined as an algo order in S1101), the execution simulation system 1 logically examines the validity of the brand and price of the algo order to be registered. Check (S1103).

  When the algo order is logically wrong, the contract simulation system 1 creates a reception error notification including the identifier of the algo order. Next, the contract simulation system 1 transmits the created reception error notification to the algorithm trading system. Then, the contract simulation system 1 ends the work board registration / contract simulation process.

(Iv) S1104 (in the case of S1103 → S1104)
If the algo order is logically correct, the contract simulation system 1 attempts to reflect the algo order on the simulation work plate 234 (S1104). For example, when the algo order is a correction order or a cancellation order, the contract simulation system 1 determines whether the order (buy order or sell order) requested to be corrected or canceled by the algo order remains on the simulation work board 234. Determine whether or not.

  If the algo order cannot be reflected on the work board 234, the execution simulation system 1 creates an execution error notification including the identifier of the algo order. Next, the contract simulation system 1 transmits the created execution error notification to the algorithm trading system.

  On the other hand, when the algo order can be reflected on the work board 234, the contract simulation system 1 registers the received algo order in the simulation work board 234 in time series (S1104). Specifically, when the algo order is a sell order, the contract simulation system 1 selects from the simulation work board 234 a record in which the price specified in the algo order matches the indicative price of the simulation work board 234. To do. Next, the contract simulation system 1 adds the number of shares specified in the Argo order to the sales volume of the selected record. On the other hand, when the algo order is a sales correction order or a sales cancellation order, the contract simulation system 1 uses the simulation work board 234 to record a record in which the price specified in the algo order matches the indicative price of the simulation work board 234. Select from. Next, the contract simulation system 1 subtracts the number of shares designated by the Argo order from the sales volume of the selected record.

  When the algo order is a buy order, the contract simulation system 1 selects from the simulation work board 234 a record in which the price specified in the algo order matches the quote price of the simulation work board 234. Next, the contract simulation system 1 adds the number of shares specified in the algo order to the buy price of the selected record. On the other hand, when the algo order is a purchase correction order or a purchase cancellation order, the contract simulation system 1 uses the simulation work board 234 to record a record in which the price specified in the algo order matches the indicative price of the simulation work board 234. Select from. Next, the contract simulation system 1 subtracts the number of shares specified in the algo order from the bid amount of the selected record.

  As described above, the contract simulation system 1 registers the algo order in the simulation work plate 234.

(V) S1105
The contract simulation system 1 determines whether or not the order is contracted based on the simulation work plate 234 (S1105). Specifically, the contract simulation system 1 determines that the order is executed when the value of “1” or more is stored in both the sales volume and the sales volume of any record of the simulation work board 234. To do. Further, the contract simulation system 1 determines that the order is executed even when a value of “1” or more is stored in either the sales volume or the sales volume of the record indicating the information related to the market order.

  If the order is filled, the process proceeds to S1106. If the order is not filled, the process proceeds to S1108 as it is.

(Vi) S1106
When the order is executed, the contract simulation system 1 executes the order based on the simulation work plate 234 (S1106). Then, the contract simulation system 1 subtracts the contracted number of shares from the selling price and the buying price of the simulation work plate 234. Thereby, the contract simulation system 1 updates the simulation work plate 234 from the state before the contract to the state after the contract.

  Further, the contract simulation system 1 determines whether or not the contracted order is an algo order. If the executed order is not an algo order, the process proceeds directly to S1108.

  On the other hand, when the executed order is an algo order, the execution simulation system 1 creates an execution notification including the execution price and the execution height. Then, the contract simulation system 1 transmits the created contract notification to the algorithm trading system.

(Vii) S1107
Further, the contract simulation system 1 calculates the initial impact P0 based on the contract result of the algo order (S1107). For example, the execution simulation system 1 calculates the intermediate value (midprice) between the lowest price of the selling order registered in the simulation work board 234 and the highest price of the purchase order, and the simulation work board 234 immediately before the execution and the The calculation is performed for each of the simulation work plates 234 immediately after the contract. Then, the contract simulation system 1 sets the difference between the two calculated mid prices (change amount of the mid price) as the initial impact P0.

  Next, the contract simulation system 1 compares the updated updated simulation work board 234 with the simulation work board 234 immediately before the work board registration / confirmation simulation process is performed, thereby performing tick data in the simulation. Create Therefore, the contract simulation system 1 stores both the updated latest work board for simulation 234 and the work board for simulation 234 immediately before the work board registration / contract simulation process is performed. Specifically, the contract simulation system 1 holds the current date on the simulation as a transaction date of tick data. The contract simulation system 1 holds the current time on the simulation as the time of the tick data.

  Further, the contract simulation system 1 holds the identifier of the brand to be simulated as a brand code of tick data. Further, the contract simulation system 1 holds the value calculated by adding “1” to the record sequence number of the tick data created immediately before as the record sequence number of the tick data.

  Further, the execution simulation system 1 holds the price at which the order is executed as the execution value (current value) of the tick data. The contract simulation system 1 holds the contracted number of shares as the contract height of the tick data.

  Next, the contract simulation system 1 selects, from the simulation work board 234, a record in which the sales quantity of the simulation work board 234 has changed by the work board registration and execution simulation process. Then, the contract simulation system 1 holds the quote price of the selected record as the bid price of the tick data. Further, the contract simulation system 1 holds the sales volume of the selected record as the sales volume of the tick data.

  Further, the contract simulation system 1 selects, from the work plate for simulation 234, a record in which the purchase quantity of the work plate for simulation 234 has changed by the work plate registration / confirmation simulation process. Then, the contract simulation system 1 holds the quote price of the selected record as the bid price of the tick data. Moreover, the contract simulation system 1 holds the bid price of the selected record as the bid price of the tick data.

(Viii) S1108
As described above, the contract simulation system 1 creates tick data in the simulation (S1108). Further, the contract simulation system 1 transmits the created tick data to the algorithm trading system 24 as market price information. Further, the contract simulation system 1 stores the created tick data in the result file 239. Thereafter, the contract simulation system 1 ends the work board registration / contract simulation process.
