Support if Mr A buys 10 lots of 17000ce in Nifty and Mr B sells 10 lots of call in Nifty then the total Oi on 17000 strike price will be 10.
So Oi is basically the number of outstanding contracts which are not squared off.

#15100 strikes OIs are still away, though 15100PE OI has risen sharply since morning but unable to cross above 15100CE OI.. any crossover intraday shall further fuel up the rally....otherwise Nifty may close below or around 15100 cash levels today. #JUSTaVIEW pic.twitter.com/6aQIPEFx3h
