~ In 2016-2018 OI works really well as market not moving 300-500 Points daily in Banknifty ( 100-200 Point in Nifty )
~ Below 15 Vix It may works today’s also
~ For Today’s condition its totally irrelevant for retails traders as there are so many players trading time based straddle like 9:20 , 9:25 , 10:00 , 11:00 and soo on as they can create OI on both sides
~ Although If anyone wants to track OI data then he/She only track ATM +- 1
~ Now a days Future OI is more relevant then OI analysis in options because of time based trading
