when taking a position on any direction suppose you want to buy 5200 pe at spot nifty 5270 then there should be reasonable amount of OI build up at 5200 ce with covering in 5300 pe OI. as of now even you are with nifty put since morning you would not have made reasonable amount as no oi covering at those levels, as you see 5300 put in morning at 9.30 was at 80 now quoting at 90 as there is no huge covering option value generally increases if there is some scare and oi covering at respective levels
