It is not likely that market will be in a mode of "sell off", thus breaking down of Nifty below 5100 level is unlikely.
The range will be still valid for 5325 - 5600. The play will be for small gain and on either side. On normal trading days, you play with negative bias and watch out for pull back to play other trade.
Any Long trade should be wind up once nifty breaks 5325 on spot.
