Kiran,
With respect to DLF,it is being observed that at Strike Price 200 calls are getting covered.However there is heavy change in OI at 180 and 190 puts.Is that Put accumulation or Put Writing happening.Kindly can you throw some light on it.To me it seems Put accumulation because traders are covering their calls at 200 which means they dont expect DLF to cross above 200.Whats your view on this.
