Nifty having a gap down opening around 17000 levels.
20 APR Virgin CPR is a strong support for Nifty if that is getting compromised then we can expect Nifty to test the next support of 16800 & 16700 levels before getting a bounce back.
In case the virgin CPR gives a good support we can expect a pull back from these levels.
Any good support around 16800/16700 we can again expect a bullish reversal.
