The Design And Implementation Of Securities Real-time Quotation System

With the securities market information technology’s progressing, electronic transactions is times of fashion for the development of securities market, thus, each securities companies launched fierce competition on the trading system. Essentially, the securities company’s competition is just the competition of function and service, the trading system is the important means of trading service which is provided by securities companies. Therefore, securities companies driven by various are paying attention to the trading system in the above factors, make the trading system as its core competitiveness of development. In recent years, each securities companies increased continuously in trading system of investment, under the support of these funds, the trading system also accelerate its renewal speed. Only by continuously updated trading system to adapt to the need of economic development, such as introducing new trading products, expand on-line transactions of capacity, otherwise, once the transaction system couldn’t keep up with economic development’s needs, the poor performance and stability will also decline disadvantages such as one exposure. As an important part of trading system, design and implement a real-time quotation with good performance, strong stability is very practical and economic significance for securities company.Real-time quotation system assumes the responsibility of the important functions, such as the processing, sending and storaging the securities commodity relevant data and trading data provide quotation trading data for the outside and provide basic data for the each subsystem on the inside. Real-time quotation system aims to become the middle of the platform serve as an stock exchange and the client sales system, consolidated and calculated the data of all transactions in real-time, so it can let stock exchange and the client business system without having to focus on organzing the data of business logic, while focus on the interaction with users. The new generation quotation system designed special structure and data communication mode for for real-time performance, handling ability and stability requirement, make it to undertake data transfer and storage platform of whole securities trading system. In this paper, it briefly introduces the GL SLC API (GSA) and makes a deep research on the technologies concerning the real-time quotation system. It mainly discusses the system structure of GSA, the definition of message, and the flow of communication between GL server and the quotation system (use the FSM). The thesis puts forward the core thoughts on the real-time quotation system’s application platform and modulized design methods, in which the platform framework and each function module are introduced. It also makes analysis and designing on the procedure flow of the platform.The research product has already been applied in business and the system has been working steadily in securities trading system.
