Bearish positioning

  • FII short build-up: long OI −3.3K, short OI +3.6K.
  • FII net sits at the 85th percentile of the last 20 sessions (+1.1σ).
  • Over five sessions FII net changed by +15.9K contracts.
  • Client (+2.31 L) is on the opposite side of FII (−2.80 L) — a divergence, which needs price confirmation to mean anything.
What would change the view

Track whether the FII side keeps adding OI and whether price follows; a run of FII short covering would signal the divergence resolving.

Every futures contract has a long and a short side, so positions across participants offset. A one-sided read from a single participant is context — the size of the gap between FII and Client matters more than either bar.

UNDERSTAND THE REPORT

Positions, explained.

Know what the numbers measure before comparing them.

Open interest vs trading volume

Open interest counts outstanding contracts at the report date. Trading volume counts contracts traded during a session. Net position is long OI minus short OI; daily net change compares two reports.

FII long–short ratio vs long percentage

The long–short ratio is long contracts ÷ short contracts. Long percentage is long ÷ (long + short) × 100. For example, 40 long and 60 short contracts give a ratio of 0.67 and a long share of 40%. A zero short position makes the ratio undefined.

Client and Pro are different categories

Client includes retail and other client accounts; it is not a pure retail measure. Pro represents proprietary positions. Aggregate futures and options positions can include hedges, spreads and arbitrage, so net OI alone does not establish market direction.

Source and reporting limits

NSE publishes participant-wise OI in its end-of-day derivatives reports. The summary here aggregates index futures rather than isolating NIFTY or BANKNIFTY. Report availability and ingestion delays can affect the latest displayed date.
