This paper presents a method for forecasting the moving direction of Shanghai Stock Composite Index (CCI) through constructing the feature pattern vectors containing the characters of the market structure according to the profitunity approach and adopting SVM to perform pattern recognition. First, the market trend forecasting is considered as a pattern recognition problem. Second, the pattern vectors are formed with the help of the investing expertise, the profitunity approach which devises a set of rules of predicting market moving trend by observing some variables (designed from the market data) and their combinations. Then, the support vector machine is employed to perform the pattern recognition, mapping the pattern vectors into class space of trend moving up and down. Finally, a group of simulations are given, and the results show the good performance that the correct rate of forecasting reached about 70%.
