Immediate resistance for Nifty is the CPR, in case any support at CPR we can possibly expect Nifty to teste out Bearish Reversal & R1.
There is a quite a resistance for Nifty around R1 & Bearish Reversal Zones, any rejection triggers from these zones is a selling opportunity for the lower targets as marked on the charts.
In case4 of S1 getting compromised we can see more selling pressure or else it would be trading in yesterday's price range.
