Price difference trading is obtained by capturing small changes of market prices, traditional trading systems are all realized in a pure software mode, and data analysis, management and control are all completed by a CPU. In the face of a very volatile market, trading opportunities tend to be vanishing somewhat. Conventional approaches take a long time to deal with such high concurrency, large bandwidth problems, resulting in a time delay of up to several hundred microseconds between the triggering of a transaction signal and the completion of the transaction.
The price difference refers to the difference between the incoming price and the outgoing price. Because the difference is very small, when a signal comes temporarily, a preset trading strategy needs to be executed at the first time, the real-time performance of order execution is required to be in a microsecond or even a nanosecond level, meanwhile, as the fused products become rich day by day, more and more data need to be monitored, the traditional price difference trading requires a trader to send an order (buy or sell a certain financial product) to the market at a certain price, and the price difference is set, after the order sent by the trader is in a deal, an order state monitoring system immediately generates a price difference trading signal and informs an order management system to send the order in the opposite market direction according to the preset price difference (namely, the order is sent immediately after the order is bought in the deal, and the order is sent immediately after the order is sold in the deal).

The invention also discloses a self-adaptive price difference trading method based on the FPGA, which is characterized by comprising the following steps: the method comprises the following steps:
step one, a client sends an order sending instruction to a price difference trading module in the FPGA, the price difference trading module transmits the order sending instruction to an order processing module, and order information is stored in the FPGA;
the received order sending instruction is transmitted through the PCIE bus, and the order processing module in the FPGA stores order information in a BLOCK RAM of the FPGA and is used for sending the counter-hand order after receiving the transaction information.
Step two, after the order data are processed by the order processing module, the order data are transmitted to the network connection module, and the network connection module adds the specified data and then transmits the data to the exchange;
the order processing module completes the functions of packaging, order data management and storage, and transmits packaged FIX protocol data to the network connection module, the network connection module adds and removes packet header data with specified data being TCP/IP, and an interface transmitted to the exchange is a PHY physical layer interface.
Step three, after receiving the order, the exchange returns a response message;
fourthly, after the network connection module in the FPGA receives the returned order information, the specified data is removed, the order information is transmitted to the order processing module for analysis, and if the return transaction information of the transaction exchange is received, the market information acquisition module in the FPGA reads market information of the same product;
the market information acquisition module reads market information from the DDR/QDR.
And step five, a price calculation module in the FPGA carries out comparison calculation according to the read product market information and the price difference or percentage set when the client places an order, calculates the price of the order for the backhoe, outputs the newly calculated price and other information and completes the sending of the order command for the backhoe.
Specifically, as shown in fig. 2, a data packet such as a market quotation and an order sent by a transaction is received through a high-speed network card, and the FPGA analyzes the data packet according to a protocol to obtain market quotation data and an order state at present.
Selecting financial products, selecting the financial products, setting price difference according to the price fluctuation condition of the products, then sending an entrance order (buying or selling) at a reasonable price, sending a corresponding instruction to the exchange by the order management system, starting to continuously monitor the order state if the order is accepted by the exchange, and informing the order management system once the order is found to have a deal.
Depending on the direction of entry (buy or sell), in the opposite direction, orders are placed at a predetermined price difference. The latest quote is obtained by scanning the market quotation, and if the current market quote is better than the preset price of the anti-hand list, the quote of the anti-hand list is automatically adjusted.
The market data shown in fig. 3 shows the price of the current partial order and the size (quantity) of the order, the trader places a buy order at the price of 9.99, the order management system places the order to the exchange and monitors the status of the order in real time. Once the order is committed, a counterhand is immediately placed, since the entry is a buy order (make many), the counterhand order must be a sell order (level), the size of the counterhand depends on the size of the buy order that has been committed, the order quote is calculated from the buy price plus a specified spread, in this case the buy price is 9.99, if the set spread is 3, the price quote for the counterhand order is 10.02, if the counterhand order is committed, the trade is paid 0.03 (regardless of trade commission, etc.). If the admission is a sell (make a null), the trader sells at a price of 10.01 with a price difference of 5, and the corresponding buy order is placed at a price of 9.96 to level immediately after the 10.01 sell order has been filled.
As shown in fig. 3, when the user completes the order at the 9.99 price, the user plans to make a return order at 10.02 according to the set price difference 3, but the market quotation is as shown in fig. 4, the optimal price of the order should be 10.03 which is 0.01 higher than the preset 10.02, and the price of the order can be adjusted in time to obtain a better price of the return order as long as the return order is not completely completed through real-time scanning of the market quotation data. For more purchases, the price quoted for the counter-hand order is not lower than the preset price (purchase price + price difference), and the higher the price quoted, the higher the profit obtained; and for selling to make a null, the price of the contrahand order is not higher than the preset price (selling price-price difference), and the lower the price, the higher the profit. The profit can be effectively enlarged and the risk can be reduced through the self-adaptive quotation.
The parts not described in the specification are prior art or common general knowledge. The present embodiments are to be considered as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
