(L-S....Long First & Short Later).....Bank Nifty could be a good example for polarity reversal. Bank Nifty could bounce from 18500-18525 zone if holds in that area for some time on 4th Aug 2016 session... two yellow arrows shown on left hand side could form hurdle in Bank Nifty's bounce --if it starts bouncing...
Polarity Reversal---Support turns into resistance & vice-versa.... 1st Hurdle for Bank Nifty could be 18715--18730 zone...
Look for these boxes as resistance zone for Bank Nifty in coming session of 4th Aug 2016..before they start falling again...
Current Price-18585
