Nifty 17854 - Has resistance grey zone at 17894-17931 and another grey zone is 17682-17633.
Market Data suggests accumulation of long positions and PCR has raised from 0.8 to 1.1 suggests strong support buildup.
Last day change in OI @ 0.54 (204638 / 377510 ) suggests short buildup is around twice the long buildup.
So we expect some resistance at the resistance grey zone initially and Nifty would be able to break through the resistance with underlying strength.
