Parabolic SAR is an indicator and basically it indicates the momentum of an assets when the possibility of change the momentum. That is upward or downward change. In a chart Parabolic SAR, RSI and Stochastics oscillator were added to see the buy and sell signals. We know when RSI and Stochastics leave their Oversold area then they generate buy signals. Take a example of HR textile. In 3rd March 2011 we have seen a buy signals. If we look previous data then we find RSI and Stochastics Oscillator were in oversold situation and giving buy signals. These three Indicators buy signals were formed one after another and we can take it a good trade. Similarly look at the 3rd April 2011. That time RSI and Stochastics Oscillator were overbought situation and Parabolic SAR was in Downtrend. If anyone can use these three indicators then he or she can get easily buy signal.
