How to Read “Net” Open Interest
Net OI is long contracts minus short contracts. A positive number means more long than short contracts; a negative number means more short than long. It shows positioning at the end of the day, not a guaranteed market direction. Option positions can include hedges, spreads and arbitrage.

Frequently Asked Questions
What is participant-wise open interest?
It is a daily NSE report showing the outstanding long and short F&O contracts held by four groups: Clients, DIIs, FIIs and Pro (proprietary traders).
Does a net short by FIIs mean the market will fall?
Not necessarily. Net positions can include hedges against cash-market holdings and option spreads, so they show positioning, not a forecast.
Where can I check the official data?
NSE publishes the participant-wise open interest file daily on its website under the F&O reports section.
