Is there any relation between Open interest of calls and puts. The figures appear to be self contradictory sometimes. For instance
Dear @anugnani, Firstly I am not a Senior Member sorry for that.
As per Ur query you just monitor OI with change in OI but not Price change which indicate STRIKE has WRITER or BUYER.
PRICE RISE ---- OI FALL than — SHORT COVERING.
PRICE FALL ---- OI RISE than — SHORT BUILDUP
PRICE RISE — OI RISE than — LONG BUILD UP
PRICE FALL — OI FALL than — LONG UNWINDING
I see PRICE of all strike of CE OPTION is RED/NEGATIVE/FALLING means trader are WRITING CALL.
