The Design And Implementation Of Securities Fast Order Processing System

In Recent years, along with the development of the capital market in China, the mode of the security transaction is continuously enriched. Many kinds of financial related derivative products were presented, which aroused investigators’ enthusiasm increasingly for cross investment products and inter-market arbitrage. Those investigators have made considerable interest for security companies, while they also raised higher request on order process system, which mainly concerned in reducing the transaction processing time and supporting programmatic transaction integration. In order to maintain competitiveness in such intense competition, security companies are in dire need of new order processing system which can accomplish rapid order generation and declaration, and also can obtain the information on return of shares in high speed in order to provide high quality security transaction service for the senior level investigators who are susceptible to speed.Currently, the security industry is in lack of refined fast order processing system in China. Therefore, this paper mainly targets in improving real-time order processing with all aspect, dealing with the design of an order processing system that adjusted to the characteristics of high-frequency trading. Firstly, has defined the request of both high-frequency trading investigators and security companies on fast order system, which based on the investigations on the characteristics of those investigators. Secondly, figured out the functional boundary of the system on the strategy of loose coupling and high-cohesion, and divided the system into four-level architectures. Then designed the data base structure, application middleware and communication middleware, meanwhile, the design of loading some of the data base table dynamically to the shared memory has dramatically improved the system performance. Additionally, customer access gateway is designed, which corresponds with the characteristics of high-frequency trading business. This customer access gateway is able to shield against invalid request, which has relieved the pressure of programmatic client transaction on the servers. At last, has designed the offer access gateway which support pushing functionality, and realized the return of the stock exchange back to client without delay. Also has discussed the design of the interface among fast order system, teller of the security companies and the bookkeeping system.
