Bank Nifty is currently trading between two gaps.
While the upper gap will act as a stiff resistance the lower gap (even bigger gap) will act as a strong support.
In near terms, although it has a bearish insight it should not cross the lower gap.
So, long trades (if taking a contrarian view) should be taken with strict stop-loss.
Guess, the trend will mature in coming one or two days.
Till then be cautious.
