🌙 FII/DII Evening Report — Mon, 20 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 (20-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 -2,19,823 -0.46 Strong Bearish

DII +58,806 -0.66 Strong Bearish

Client +1,49,384 +0.31 Strong Bullish

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 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 sold ₹1,121 Cr in cash while simultaneously unwinding index longs through Long Unwinding with Weak Bearish FSR -0.10, but the critical cross-check reveals this is not genuine directional bearishness—Nifty futures showed Strong Bullish FSR +0.20 Short Covering and stock futures remained Neutral, meaning the index long unwinding is mechanical position reduction paired with stock conviction that remains intact at +553,703 accumulated net longs. Index options Combined OFR turned Strong Bearish -0.70 for FII, confirming the derivatives shift is real, but the conviction score landed at -2/3 Moderate Bearish (both futures and options bearish, cash neutral) rather than -3, signaling this is a positioning adjustment within an existing structure rather than a directional reversal. BankNifty's Strong Bearish FSR -0.49 with Short Buildup activity shows FII is actively adding shorts in the banking index while covering Nifty shorts, establishing a clear tactical rotation from broad index to sector-specific bearishness. DII's index futures OFR collapsed to Strong Bearish -0.66 while their stock futures OFR hit the extreme -1.00 Strong Bearish, meaning domestic institutions are simultaneously unwinding both index and stock positions with zero conviction—the domestic floor that held Friday has cracked entirely, and DII is now aligned with FII in selling rather than providing support. Client and Pro remain opposed to FII in index futures with net longs of +149,384 and +11,633 respectively, but Client's index options Combined OFR is Strong Bullish +0.40 while their stock options Combined OFR is Moderate Bullish +0.17, revealing retail conviction is building in options while FII and DII unwind—this is the classic late-cycle structure where institutional money exits and retail conviction builds into weakness.

Friday's morning report established FII as carrying Moderate Bullish conviction (+2/3 score) with index shorts being covered and stock longs accumulated, while DII provided mechanical domestic support despite weak conviction. Today's close broke that pattern decisively—FII shifted to Moderate Bearish conviction (-2/3 score) with index long unwinding and BankNifty short buildup, while DII's support collapsed entirely into Strong Bearish positioning across both index and stock futures, eliminating the domestic institutional floor that existed Friday.

The week's established pattern of FII defensive rebalancing has inverted into active tactical repositioning with BankNifty shorts being added while Nifty shorts are covered, signaling FII is rotating bearishness from broad index into specific sectors rather than distributing outright. DII's complete capitulation from mechanical support to aligned selling removes any institutional buffer, leaving the market structure dependent on Client and Pro conviction which remains opposed to FII but is now unhedged—weekly expiry tomorrow will force rapid unwinding and the absence of domestic institutional support means any Client position liquidation will lack a buyer. FII's stock futures remain net long at +553,703 but with Neutral FSR +0.00, indicating stock conviction is pausing while index and sector tactics dominate, establishing an environment where tactical bearishness in derivatives is masking underlying equity accumulation rather than genuine distribution.
