Research And Implementation Of Futures Exchange Simulati On System

The properties of futures exchange systems are as follows. For huge amounts of users register in the system, the concurrency can be very high. Because the market is changing rapidly, every user wishes to get the results of their entrust returns and deals returns in a short time. All the entrust data are processed by the futures exchange system in the futures exchange. The futures exchange system is a very important business system. The steadiness of operation process affects the safety of the whole exchange system. A futures exchange system is designed in this paper with C++ and My SQL database.As the design objects and functionalities requirement, the system architecture is composed of client, server and database. The user interface of the client is developed with the Qt technology.The clients’ functionalities are opening user accounts and closing user accounts in the client system, opening money accounts and closing money accounts, resetting password, ordering and commissioning. The server system simulates simple exchanges, and sending the results back to the client. Network communications are based on sockets. When users send an operation command,the client communicates with the server with sockets. After the server has processed the trading,data is written into My SQL database.After customers play their orders, if the futures comply with the trading rules, exchange will be conducted. When sellers and buyers achieve matching exchange, the final price is generated from the system. At last the futures trading system simulating is completed.
