What participant-wise open interest shows
NSE publishes participant-wise open interest after every F&O session. It splits the open long and short contracts in index futures, stock futures, index options and stock options among four categories: foreign institutional investors (FII, also reported as FPI), domestic institutional investors (DII, such as mutual funds and insurers), proprietary traders (Pro, brokers trading their own money) and clients (everyone else, mostly retail and non-institutional accounts).
The FII long-short ratio most often quoted is the FII share of long contracts in index futures: long contracts divided by long plus short. A reading of 50% means FIIs hold as many long as short index futures; 25% means one long contract for every three short. Some sources quote long divided by short instead, shown here as the long-short ratio.
A short futures position is not necessarily a view that the market will fall. Foreign investors often hold Indian shares and use index futures to hedge them, and positions roll over around each monthly expiry. History gives a reading context, not a verdict.
Methodology
- Participant-wise open interest in NSE equity derivatives as published by NSE after each session, 2 Jan 2012 to 28 Oct 2026: 3,633 sessions. Counts are contracts, not rupee values.
- FII long share: FII long index futures contracts as a percentage of FII long plus short index futures contracts. Long-short ratio: long divided by short. Net: long minus short.
- Percentile: the share of all stored sessions with a long share at or below the latest one. Averages are simple means of daily readings over the trailing 1 and 5 years and the full history.
- Yearly table: the last reading of each calendar year and that year's average, highest and lowest reading. 2026 is shown year to date.
- The chart plots the last reading of each week. Updated after each F&O session.
Data as of 28 Oct 2026. Historical derivatives positioning data for research and information only. Not investment advice, and not a forecast: a futures position can hedge holdings elsewhere, so it does not show what any participant expects. Markdown version.
