Open interest is the number of outstanding contracts not yet settled in an expiry. This lesson explains it from scratch and shows how futures open interest, combined with option pricing, helps gauge sentiment and pick trade ideas.
It covers the four price-OI combinations: longs (price up, OI up), long unwinding (price down, OI down), shorts (price down, OI up) and short covering (price up, OI down). It then applies open interest to Nifty, BankNifty and other liquid scrips, including using option chain open interest to identify support and resistance and for option selling.
