In this paper we summarize various possible techniques such as Crossover Prediction Model or the classical Prin cipal Component Analysis (PCA) tool to include exoge nous data. Furthermore we propose a new method for volatile time series forecasting using Independent Compo nent Analysis (ICA) algorithms and Savitzky-Golay filter ing as preprocessing tools. The preprocessed data will be introduce in a based radial basis functions (RBF) Artificial Neural Network (ANN) and the prediction result will be compared with the one we get without these preprocessing tools.
