Nifty recovered well after testing the previous demand zone and managed to close above the next day CPR levels.
In case nifty opens flat and tests the CPR, the bullish Reversal zone of 17493 should act as a good support and can again test the previous day close and if that is taken out we can again expect to test 17631 & higher levels.
Any rejection around 17631 again , we can again expect Nifty to be in yesterday's range and can test the Bearish Break out zone of 17423 & lower.
