🌙 FII/DII Evening Report — Tue, 21 Jul, 2026

FSR (Flow Strength Ratio): Range -1 to +1

Measures how one-sided FII's futures buying vs selling was — not the absolute size but the relative aggression. Two sessions with identical net contracts can have very different FSR values depending on total activity.

Positive = FII bought more contracts than sold (bullish flow)

Negative = FII sold more contracts than bought (bearish flow)

Strength: >=0.30 Strong | >=0.15 Moderate | >=0.05 Weak | <0.05 Neutral

Reliability: Nifty most reliable → BankNifty → MidCap Nifty → FinNifty and NiftyNext50 least reliable. Stock futures is a broad signal only — individual stock breakdown not available.

OFR (OI Flow Ratio): Range -1 to +1

Measures how a participant's accumulated long and short positions shifted compared to the previous session — not how much they traded today but how their total positioning changed.

Positive = participant adding longs or closing shorts (bullish positioning shift)

Negative = participant adding shorts or closing longs (bearish positioning shift)

Strength: >=0.30 Strong | >=0.15 Moderate | >=0.05 Weak | <0.05 Neutral

Caution: Futures OFR is especially misleading for FII because portfolio hedging inflates their futures positions. For DII, Client, and Pro, futures OFR is more likely directional but still less reliable than options Combined OFR. Always prefer options Combined OFR over futures OFR when they conflict.

Combined OFR: Range -1 to +1

Merges Call OFR and Put OFR into one unified options signal per participant. Shown for options rows only — futures rows show dash because futures have only one OFR value.

When Call and Put OFR agree — high confidence directional signal.

When Call and Put OFR conflict — dominant side wins but with reduced conviction. The conflict itself is meaningful.

Put OFR sign is automatically flipped so positive always means bullish — consistent with calls and futures.

Strength: >=0.30 Strong | >=0.15 Moderate | >=0.05 Weak | <0.05 Neutral

Signals:

Long Buildup = OI up + Net Buy → fresh longs added, bullish

Short Buildup = OI up + Net Sell → fresh shorts added, bearish

Short Covering = OI down + Net Buy → shorts being closed, bullish

Long Unwinding = OI down + Net Sell → longs being closed, bearish

Conviction Score (S1+S2+S3): Range -3 to +3

Three independent FII signals combined — futures positioning shift, options positioning shift, and actual cash deployment.

S1 = Index Futures OFR → >+0.05 bullish | <-0.05 bearish | else neutral

S2 = Index Options Combined OFR → same thresholds

S3 = FII Cash Net vs dynamic threshold (75th pctile of past 1yr flows)

+3 Strong Bullish | +2 Moderate Bullish | +1 Weak Bullish | 0 Neutral

-1 Weak Bearish | -2 Moderate Bearish | -3 Strong Bearish

Hedging Warning: fires when S1=S2 but S3 contradicts — FII using derivatives to hedge equity portfolio, not a directional bet. Do not treat conviction score as directional when active.

Battle Table:

Positive net = net long (bullish) | Negative net = net short (bearish)

Neutral = less than 2% directional bias

Aligned = same direction as FII | Opposed = opposite to FII

★ = Dominant participant (largest absolute net position)

When Client Opposed to FII → historically FII tends to be correct at inflection points.

👥 PARTICIPANT OI (21-Jul-2026)

Note: All participant OI data is combined across all expiries — NSE F&O data only. Not expiry specific. Current month contracts are the most liquid — majority of activity happens there — data can be used accordingly.

Conviction Score is available for FII only. For DII, Client, and Pro — use options Combined OFR as their primary directional signal. Futures OFR is especially misleading for FII due to portfolio hedging — less so for DII, Client, and Pro who are more likely directional.

Note: Net OI = Long OI - Short OI. This is NOT daily buy/sell — it is the total accumulated position. Positive = longs are more than shorts. Negative = shorts are more than longs.

FII negative Net OI does not always mean FII is heavily bearish — FII may use index futures to hedge their equity portfolio. However if options Combined OFR also turns bearish simultaneously, it is genuine directional conviction, not hedging. Always cross-check with options Combined OFR and FII Conviction Score before concluding.

FII negative Net OI does not always mean FII is heavily bearish — FII may use stock futures to hedge individual stock positions. However if options Combined OFR also turns bearish simultaneously, it is genuine directional conviction. Always cross-check with options Combined OFR and FII Conviction Score before concluding.

Hedging Warning : Not Active

Note: Conviction Score is FII only. For DII, Client, and Pro — use options Combined OFR as their primary directional signal. Futures OFR is especially misleading for FII due to portfolio hedging — for other participants it is more likely directional but options Combined OFR remains the stronger signal.

FII bought ₹1,650 Cr in cash while aggressively building index shorts through Short Buildup with Strong Bearish FSR -0.49 across the index complex, creating a critical cross-check failure—cash buying and futures selling point opposite directions, which typically signals hedging, but index options Combined OFR also turned Moderate Bearish -0.20 and stock options Combined OFR collapsed to Strong Bearish -1.00, confirming the futures shorts are genuine directional conviction, not portfolio hedging. FII's conviction score landed at -2/3 Moderate Bearish with S1 and S2 both bearish while S3 remained neutral on cash, meaning FII is expressing bearish conviction through derivatives while deploying cash tactically—this is not hedging but rather a deliberate short buildup paired with selective cash accumulation into weakness. Stock futures net selling of -29,757 contracts with Neutral FSR -0.04 masks the real story—stock futures OI jumped +30,357, meaning FII added fresh short positions in individual stocks while maintaining index shorts, establishing a coordinated bearish stance across both index and stock derivatives. DII collapsed further into Strong Bearish positioning across index options Combined OFR -0.20 and stock options Combined OFR -0.99, with index futures OFR hitting extreme -1.00, confirming domestic institutions are now fully aligned with FII selling rather than providing any support floor. Client remains opposed to FII with net long index futures of +148,081 and strong bullish positioning in both index options Combined OFR +0.16 and stock options Combined OFR +0.72, but this opposition is now occurring against coordinated institutional selling from both FII and DII simultaneously—the historical tendency for FII to be correct when opposed by clients is being tested by the absence of any domestic institutional buffer.

Monday's morning report established FII's Moderate Bearish conviction through index long unwinding and BankNifty short buildup while DII's support had already cracked into Strong Bearish alignment. Today's close extended that pattern decisively—FII shifted from unwinding existing index longs into actively building fresh index shorts with Strong Bearish FSR -0.49, while DII's bearishness intensified across both index and stock options into extreme -1.00 positioning, meaning the domestic institutional floor that was already cracked yesterday has now completely vanished into aligned selling. The morning's tactical rotation into banking sector shorts has evolved into a full short buildup across the entire index complex with coordinated stock futures shorting, establishing that today is not a continuation of Monday's rebalancing but rather an acceleration into genuine directional bearishness from both FII and DII.

FII has now built Moderate Bearish conviction across two consecutive sessions with index short buildup accelerating from Monday's unwinding into today's aggressive Short Buildup with Strong Bearish FSR -0.49, while stock futures shorts are being added simultaneously with OI expansion of +30,357. DII has completely inverted from any support role into extreme bearish alignment across all derivatives instruments, removing any institutional buffer for Client longs that remain opposed to FII. Weekly expiry today forces position resolution, but the critical development is that both major institutional participants—FII and DII—are now on the same bearish side with coordinated short buildup and options positioning, establishing an environment where Client's opposing long positions face liquidation pressure into expiry with zero domestic institutional support to absorb selling. The institutional environment entering tomorrow is fundamentally shifted from yesterday—this is no longer tactical sector rotation but coordinated institutional short conviction meeting weekly expiry mechanics, with the absence of any DII support creating structural vulnerability for retail long positions.
