The Research And Design Of Securities Investment System Based On Delphi

China’s economy subversive nature of the change has occurred since the reform and opening up, its growth rate so that the whole world eyebrows. China’s marketoriented economy accompanied by the vigorous pace of one step evolved. At the same time the securities industry stocks also gained increasing prosperity and development, investor demand for the securities market increasingly cognitive depth and increasingly professional, this where investors constantly improve their own quality, but also advances the stock market analysis tools.

Many large-scale international securities investment business has its own independent securities analysis system, even where individual companies have their own software development company. The securities of companies with foreign investment compared to the relatively weak in this regard, we are committed to developing its own securities analysis system based on sound rich and so their services and attract more investors and consumers to join.Research and development of this system stems from the same small-scale investments in securities companies, the ultimate goal is for these companies to develop a proprietary securities analysis software. The system description language UML, as a basis for the analysis and design of systems related technology research and development. Development of the system chosen iterative approach to development, the basic idea is to build a prototype system, then the relevant requirements analysis, requirements analysis is complete the system design, system testing and perfecting the final based on. The system can be implemented features are based on real-time market analysis, fundamental analysis, stock market information, as well as a relatively high level of stock selection function and related investment advice. The system meet the base meet the daily needs of investors, relatively suitable for small investors.This paper describes the background of the system development, the demand for the overall system architecture, system belong to a specific function module performs a detailed analysis of the design of the overall system design ideas and processes, and each sub-function modules focus on illustration and description. This is the core part of the system implementation, investment guided scribes the design principles and implementation process modules were detailed in this section system design theory for the average full use of the relevant functional modules can risk sectors, stocks and the broader market forecast, forecast accuracy to meet the basic risk control requirements of small and medium investors. Users can assess their predictive value of the investment plan, the subject of screening related stocks, according to the final completion of this investment operations. This paper also problems encountered in the development process were studied and discussed. DELPHI source code mainly written.The system is based on data warehousing, data mining and OLAP technologies, for brokers and their clients, the investment objectives of their choice analysis, risk management, and to provide effective services.
