You can see today's rally in bank nifty . Generally what happens if there is a big rally then after achieving the top the index will retrace 20-30 to a maximum of 50 percent. Hence whenever you see green candles at 30 or 50 % levels of fibo retracement you can still go long in direction of the rally. This is the move where many retailers get trapped after selling and the market bounces sharply which you can see here. If it breaches 50 percent then you can say the trend may have changed for downward 300-500 points.
