Based On The.net Platform Of Stock Analysis System Design And Implementation

With the development of the world economy and the stock market, more and morepeople take stock investment as a financing. However, many people investigate thestock very blindly and cause a great loss. There are many stock analysis software indomestic market, but most of them are familiar, they are all kinds of data that flowingchart and various curve way to show to the users, there are no intelligent analysis abilityand no suggestions for the investors. Therefore, developing a stock analysis system withcharacteristics of intelligent analysis and reasonable suggestions is imperative. Thistopic is proposed in this background conditions to carry out the related technologyresearch and development work. Through the research of existing stock analysis systemand stock analysis methods, the stock system should have stock data acquisition, stocktechnology graphic drawing, stock analysis and prediction, and other functions. Thispaper is for the purpose of making these functions realize to study and do some relatedresearch.The data of existing stock analysis software is getting from Stock Exchange, thismethod can get stock trading information timely,but this method have a high cost, anddue to confidentiality and restrictive characteristics, the information is stored mostly intext format; the structural is not strong for data analysis. The system of this topic isresearching the history of stock trading data and financial statements, finding theintrinsic value of stock, so the data acquisition requirement of real-time is not high.System data acquisition function is to use Web information extraction technology, getthe needed data from Web page and then store in a database. Therefore, this method cannot only save money, but also getting the data completely, and easily for data analysis.Stock technology graphics is the most directly way to show the stock data, so thestock technology graphics rendering is a very important part of this topic. System isbased on NET platform, using the GDI+graphics drawing technology implementrelated graphic display module, and using coordinate conversion, double buffering andother methods to solve the graphic display and refresh efficiency problem.According to the analysis, the topic take some important financial indicators as the research objects, establishment of financial analysis model is based on decision tree.Through the model analysis, summarize the rules between the movements of stock priceand financial data, and then predicting the movement of the stock.This article introduced the knowledge of the stock, discussing the overall design ofthe stock analysis system and implementation partially, eventually developed andfinished the "rational stock analysis system". In the aspect of stock data acquisition andstock movement predictions, compared with other systems, the new system shows theadvantages. After a period of testing and application, the system can accurately obtainthe required comprehensive stock data. The establishment of financial analysis, smartstock selection, volume and price analysis model have some reference value for stockinvestment guide.
