Participant-Wise Open Interest: FII, DII, Client and Pro Positions
NSE publishes end-of-day derivatives open interest split by participant type — FIIs, DIIs, Clients (retail) and Pro (proprietary trading desks). This page tracks who holds long and short positions across index futures, stock futures and options, and how that positioning changed versus the previous session.
The Four Participant Categories
FII: foreign institutional investors. DII: domestic institutions such as mutual funds, insurers and banks (DIIs are restricted in derivatives and mainly hedge). Client: retail and HNI traders trading through brokers. Pro: brokers' own proprietary desks. The four categories' longs and shorts always net out against each other — every long has a short on the other side.
What to Watch
- FII net index-futures position and its day change — the most-watched institutional signal
- Client (retail) positioning, which has historically leaned opposite to FIIs at extremes
- Day-over-day OI change by category: fresh longs, fresh shorts, covering or unwinding
- Futures versus options split — options OI includes many spread and hedge structures
- Positioning into expiry week, when rollovers reshuffle every category
How to Read the Table
- Start with the net change per participant, not the absolute OI, to see today's new positioning.
- Compare FII and Client changes — when they diverge sharply, note which side has institutional weight.
- Distinguish long buildup (price up, OI up) from short covering (price up, OI down) using the price context.
- Treat options OI with caution: multi-leg strategies make raw long/short counts ambiguous.
Limitations
- OI counts contracts, not conviction — one hedged position looks identical to a directional bet.
- Categories are aggregates: 'FII' includes hundreds of funds with opposing views.
- Options OI mixes buyers and writers of both calls and puts; net direction is not inferable from OI alone.
- Data is end-of-day — intraday shifts are invisible until the next publication.
Frequently Asked Questions
It shows how many derivative contracts each participant category (FII, DII, Client, Pro) held long and short at the end of the session, as published by NSE. It reveals positioning, not intent.
Every contract needs a counterparty, so aggregate positions must offset. At sentiment extremes, retail has historically been heavily long when FIIs are heavily short, and vice versa — worth noting but not a mechanical signal.
Regulation restricts most domestic institutions to hedging in derivatives, so DII open interest is structurally small compared with their cash-market footprint.
The long-short ratio condenses one slice of this data (FII index futures) into a single number. This page shows the full matrix — all participants, all instrument types — for deeper context.
NSE publishes participant-wise OI after each trading session; this page updates the same evening IST and shows the change versus the prior session.
Read participant-wise OI together with the FII long-short ratio and daily FII activity to understand who is positioned where — and why.
