Study on prediction of stock data based on feedforward neural network′s time series prediction. Establishing of prediction network model in multiplayer feedforward neural network′s time series prediction and the prediction design measures are discussed

based on BP network the stock data are forecasted. The precision of prediction is higher than the traditional methods. It shows that the method is receivable. BP network can be used to prediction of stock data and the precision of prediction is high. But in practice

how to select and establish appropriate neural network is needed experiment repeatedly.
