FII DII Data - Daily Institutional Buy and Sell Figures

If you've ever wondered whether the "big money" was buying or selling Indian stocks on any given day, this is the page that answers it. FII DII data shows you exactly what the largest investors — foreign funds and domestic institutions — did in the market today, and whether they're leaning bullish or bearish.

I'm going to walk you through this page the way I'd explain it to a friend sitting next to me: what each section means, how to read it, what you can customize, and — just as importantly — why any of it matters for your trades and for the economy. No jargon dumps. Let's go.

What is FII DII data? (the quick version)

FII DII data tracks the daily net buying and selling of two groups that move Indian markets more than anyone else:

• FIIs (Foreign Institutional Investors) — also called FPIs (Foreign Portfolio Investors) by SEBI. Think global hedge funds, sovereign wealth funds, foreign pension funds and overseas asset managers.
• DIIs (Domestic Institutional Investors) — Indian mutual funds, insurance giants like LIC, banks, EPFO and pension funds.

Every trading day, NSE and BSE publish how much each group bought and sold. The number you care about is the net figure:

• Positive (+) = net buying = leaning bullish.
• Negative (−) = net selling = leaning bearish.

So if you see "FII −₹8,776 Cr", it means foreign investors sold ₹8,776 crore more than they bought that day. Simple as that.

What makes this page different from most FII DII trackers: it doesn't stop at the cash market. It also shows you FII F&O positions — what foreign investors are doing in futures and options — and then folds cash + F&O into a single, plain-English signal. That combination is where the real edge is, and we'll get to it.

A quick walkthrough: how to use this page

Read it top to bottom and it tells a story. Here's each part, in order.

1. The "Today" snapshot card — your one-glance read

This is the box at the very top. Before you read anything else, this card gives you the day's verdict in one line, for example: "FII sold ₹8,776 Cr cash and sold −2,67,706 Nifty futures — looks like a confident bearish stance."

Around that line, you'll find the numbers that back it up:

• FII Cash vs DII Cash — the two arrows facing each other. This is the day's tug-of-war. When FIIs sell and DIIs buy, the card tells you who won — e.g. "DII absorbed ₹357 Cr more than FII sold." That "absorption" idea is the single most useful concept on this page (more on it below).
• Nifty Close — so you can immediately see whether the flows actually moved the index.
• FII Selling/Buying Streak — how many sessions in a row FIIs have been on the same side, plus the cumulative amount. A one-day sell is noise; an 8-session streak worth −₹55,000 Cr is a trend.
• Cash vs F&O — tells you if the cash and futures signals agree (both selling = "directional", a stronger signal) or disagree (which usually means hedging, not a clean exit).
• Today's Rank (90D) — how big today's flow was versus the last 90 days. A #8/90 day is a top-tier flow day; rank #80/90 is a quiet day you can mostly ignore.
• FII–Nifty Correlation (20D) — how tightly FII flows and Nifty have moved together lately. High correlation means "flows are driving price right now, pay attention." Low correlation means flows aren't the main story this week.

How to use it: glance at this card first. If the streak is short and the rank is low, today's FII activity is background noise. If the streak is long, the rank is high, and cash + F&O agree — that's a day worth acting on.

2. FII / DII Flow Over Time — the trend chart

This is the line chart. It plots daily FII Cash, DII Cash, and a Nifty 50 overlay so you can see flows and price on the same canvas.

Why this matters: single-day numbers lie. The signal lives in the trend. This chart lets you see, at a glance, things like "FIIs have sold 25 of the last 30 days, but DIIs absorbed 119% of it, and Nifty barely moved." That's a completely different market than "FIIs sold once and Nifty dropped 1%."

Underneath the chart you get the summary stats that matter most: 30D net for each side, DII absorption % (how much of FII selling domestic money soaked up), sell-day count, and the biggest single day in the window.

3. FII F&O Positioning — your FII F&O position read

This is the section most other sites don't have, and it's gold. It shows what FIIs are doing in futures and options — i.e. their FII F&O positions — which often reveal intent before it shows up in the cash market.

It breaks into two parts:

Futures — Net Long / Short. Sourced from participant-wise OI, this shows FII net positions in index futures and stock futures, today versus yesterday, plus the 5-day trend, total open interest and the rupee value of those positions.

• A growing net short in index futures while FIIs also sell cash = aligned bearishness.
• A net short in futures while FIIs buy cash = often a hedge, not a real bearish call.
• Stock futures going net long while index futures go short is a classic "bearish on the index, bullish on specific names" setup.

Index Options — Net Position Change Today. This shows the day's change in FII call and put positions, split into long and short. For example, heavy call shorting + call buying at the same time, stacked on cash selling, usually reads as protective hedging — reducing exposure, not panicking.

The "F&O Says" line translates all of that into one sentence so you don't have to decode it yourself.

Tip: if you also trade options, pair this with the live NSE Option Chain, Nifty OI data and the Nifty Put-Call Ratio. The full participant breakdown lives on the Participant-wise OI page, and you can check contract sizes on the NSE F&O Lot Size page.

4. The Combined Signal — cash + F&O in one verdict

Here the page does the thinking for you. It takes the cash direction and the index-futures direction and drops the day into one of four buckets:

This little matrix is the fastest way to understand behaviour, not just direction. "Bearish Strong" (selling cash + shorting futures) is a confident bearish stance. "Hedge Unwind" (selling cash but buying futures) usually means repositioning rather than running for the exit — a very different message for your trades.

Below the matrix you'll often see a historical context line: "When FIIs sold cash for 3+ days in the past, here's what Nifty did over the next 10 days." That turns today's pattern into odds based on real history — average return, hit-rate, worst drawdown, recovery rate.

5. The 5-Year Flow Heatmap

A month-by-month grid going back five years. Darker cells = stronger flows. You can switch between FII Cash, DII Cash and FII Futures views.

This is your zoom-out tool. In a few seconds you can spot things like "FIIs sold almost every month in 2022" or "DIIs have been relentless buyers all year." Patterns that take ages to see in a table jump out instantly in colour.

6. Records, Extremes & Monthly Aggregates

• Records & Extremes — the all-time biggest buy and sell days, and the biggest recent sell. Useful context: is today's −₹8,000 Cr a big deal? Compared to the all-time record sell of −₹21,106 Cr, it's meaningful but not extreme.
• Monthly Aggregates — a clean table of FII net, DII net and Nifty close by month, with year tabs (2022–2026). This is the best place to study how institutional behaviour shifted across market cycles.

How to interpret FII DII activity (with simple examples)

Here are the read-it-like-a-pro rules, with plain examples.

Rule 1 — One day is noise; the trend is the signal.
FII selling ₹2,000 Cr today and buying ₹2,000 Cr tomorrow tells you nothing. But FIIs selling for 8 sessions straight, totalling −₹55,000 Cr, is a genuine institutional stance. Always check the streak before reacting.

Rule 2 — Watch the absorption, not just the selling.
Say FIIs sell ₹8,776 Cr and DIIs buy ₹9,134 Cr. On paper that's "FIIs selling = bad", but DIIs actually bought more than FIIs sold. Net institutional flow was positive. That's why Nifty can stay flat on a heavy FII-selling day — domestic money absorbed it. When absorption is above ~100%, downside is usually cushioned.

Rule 3 — Cash and F&O agreeing is a louder signal than either alone.
FIIs selling cash and adding index-futures shorts = aligned, directional bearishness. FIIs selling cash but adding futures longs = mixed message, usually hedging. The Combined Signal matrix labels this for you.

Rule 4 — Size it against history.
Use "Today's Rank (90D)" and Records & Extremes. As a rough guide: net flows under ±₹1,000 Cr are low-impact; ₹2,000–5,000 Cr is noteworthy; above ₹5,000 Cr in either direction tends to line up with same-day Nifty moves of 0.5%+.

A quick worked example. Imagine you open the page and see: FII cash −₹8,776 Cr, DII cash +₹9,134 Cr, an 8-day FII selling streak, the Combined Signal flashing "Bearish Strong", but DII absorption at 119% over 30 days. How do you read it? Foreign money is clearly and persistently bearish — but domestic money is fully absorbing the selling, so the index is being held up rather than collapsing. The actionable takeaway: don't blindly short just because "FIIs are selling" — the floor is being defended. Watch for the day DII absorption fades; that's usually when the selling finally bites.

Settings & customization on this page

You're not stuck with one view. Here's what you can change:

• Time range on the flow chart — toggle between 7D, 30D, 90D, 1Y and 5Y. Short ranges for trading; long ranges for the big picture.
• Series toggles — show or hide FII Cash, DII Cash and the Nifty 50 overlay so you can isolate exactly what you want to compare.
• Heatmap view — switch the 5-year heatmap between FII Cash, DII Cash and FII Futures.
• Monthly Aggregates year tabs — jump between 2022, 2023, 2024, 2025 and 2026 to compare full years side by side.
• Hover for exact values — every chart point and every heatmap cell reveals the precise ₹ Cr figure on hover, so you're never guessing from a colour.

My suggested workflow: start on the 30D view with all three series on to read the current regime, flip the heatmap to 5Y to confirm the longer trend, then drop into the F&O Positioning section to see whether futures confirm the cash story.

What moves FII flows? (why foreign money comes and goes)

FIIs aren't reacting to one stock — they're moving global capital between countries. The main drivers:

• US interest rates and the Fed. When US rates rise, "safe" dollar assets pay more, so money rotates out of emerging markets like India. When US rates fall, money flows back in chasing growth. The 2022 FII exodus of over ₹1.2 lakh crore lined up almost exactly with the Fed's rate-hike cycle.
• The US dollar and the rupee. A strong dollar / weak rupee eats into FII returns (they earn in rupees but report in dollars), so dollar strength usually means FII selling.
• Relative valuations. When India looks expensive versus peers like South Korea, Taiwan or Brazil, global funds rotate to the cheaper market. Part of the 2025–26 selling came from exactly this — India's premium over emerging-market peers compressed and money chased cheaper markets.
• Global risk appetite. Wars, oil shocks, tariff threats and recession fears send FIIs toward safety. India's heavy April 2026 outflow, for instance, coincided with geopolitical tension and global tariff anxiety.
• India-specific triggers. Budget, RBI policy, elections, earnings seasons and regulatory/tax changes all shift FII appetite.

The big-picture takeaway: FII flows are mostly a global story. That's why a great Indian quarter can still see FIIs selling — the trigger came from outside.

What moves DII flows?

DIIs behave very differently, and understanding why is half the battle:

• Retail SIP money. Indian mutual funds receive steady monthly SIP inflows. That gives DIIs a near-constant pool of cash to deploy, regardless of mood. This is the structural force behind India's resilience to FII selling.
• Counter-cyclical buying. DIIs tend to buy more when markets fall (NAVs are cheaper) and ease off during euphoric rallies — the opposite of the herd. That's why they so often appear on the buy side exactly when FIIs are dumping.
• Insurance and pension allocation. LIC, EPFO and pension funds deploy long-term premiums and contributions on a schedule, not on sentiment.
• Redemption pressure. In a genuine panic, if retail investors pull money out of funds, DIIs can be forced to sell — which is why a market where both FIIs and DIIs sell together is far more dangerous than FII-only selling.

When and why FII flows matter

FII flows matter most in these situations:

1. At turning points. A multi-week shift from FII selling to buying (or vice versa) often marks a regime change before price fully reflects it. The monthly and yearly views are built to catch these.
2. In large-cap and index trades. FIIs concentrate in heavyweight Nifty 50 names. Sustained FII selling pressures exactly the stocks that move the index most.
3. When cash and F&O agree. Aligned selling (cash + futures shorts) is historically tied to deeper, multi-week drawdowns. Historically, 3+ consecutive weeks of FII net selling has correlated with Nifty drawdowns of roughly 3–8%.
4. When DII absorption fades. As long as DIIs absorb FII selling, the market holds. The dangerous moment is when absorption drops — that's when FII selling actually starts to hurt.

What FII flows are not: a same-day crystal ball. A single day's number is a poor predictor. Treat it as one input alongside price, India VIX, open interest and global cues like GIFT Nifty, which gives you an early read on overnight FII sentiment before the cash market opens.

How FII flows impact the economy (and the rupee)

FII activity isn't just a market story — it ripples through the whole economy.

• The rupee. FIIs bring in dollars to buy Indian assets and take dollars out when they sell. Heavy inflows strengthen the rupee; heavy outflows weaken it. A weaker rupee then makes imports (oil, electronics) costlier and can nudge inflation up.
• Forex reserves and the current account. Sustained FII inflows pad India's foreign-exchange reserves and help fund the current account. Sustained outflows put pressure on both, which is why policymakers and the RBI watch these flows closely.
• Bond yields and borrowing costs. FIIs invest in Indian debt too. When they pull out of bonds, yields can rise — and government and corporate borrowing gets more expensive across the economy.
• Market liquidity and confidence. FIIs have historically been a major source of market depth. Their selling can drain liquidity and dent sentiment, even in fundamentally sound companies.

Here's the genuinely important shift, though — and it's why FII flows, while still vital, no longer control India's market the way they once did. India first opened to foreign investors in 1992, after the 1991 balance-of-payments crisis, and for years foreign money was the market. But the structure has changed dramatically. By 2026, FPI ownership of NSE-listed equities had fallen to roughly 15–16%, a multi-year low, while DII ownership rose above it for the first time, powered by record domestic mutual-fund and SIP inflows. Even as FIIs pulled out close to ₹1.92 lakh crore in the first months of 2026, domestic institutions absorbed most of it and the market held far better than the old playbook would predict.

The practical lesson for you: FII flows still matter enormously — for the rupee, for large-caps, for direction — but always read them next to DII absorption. Foreign selling into strong domestic buying is a very different market than foreign selling into a domestic vacuum. This page is built to show you both at once.

If you want to go deeper on the structural shift and which stocks foreign funds are still backing, the NiftyTrader markets desk regularly breaks down FII positioning, including pieces like the FII stocks with the highest foreign shareholding.

FII DII data — FAQs

What is FII DII data?

It's the daily record of net buying and selling by Foreign Institutional Investors (FIIs/FPIs) and Domestic Institutional Investors (DIIs) on NSE and BSE. A positive net figure means net buying (bullish lean); negative means net selling (bearish lean). NSE and BSE publish it after market close each trading day.

What is FII activity, exactly?

"FII activity" simply means how much foreign investors bought and sold in a session — in the cash market and in F&O. On this page you can see FII activity day by day, the running streak, the monthly aggregate, and the 5-year heatmap, so you can tell one-day noise from a real trend.

What is an FII F&O position / FII F&O data?

It's whether FIIs are net long or net short in futures (index and stock) and how they're positioned in index options, based on NSE's participant-wise OI. FII F&O positions often reveal intent before it shows in the cash market — for example, building index-futures shorts ahead of (or alongside) cash selling signals a stronger bearish stance.

What's the difference between FII cash data and FII F&O data?

Cash data is buying/selling in actual listed shares. F&O data is positioning in futures and options. They don't always agree — FIIs can sell cash while holding futures longs as a hedge — and that divergence is one of the most useful, underused signals. The Combined Signal section on this page classifies it for you.

How does FII selling affect Nifty 50?

FIIs are concentrated in large-cap index heavyweights, so sustained FII selling tends to pressure Nifty — unless DIIs absorb it. Historically, 3+ consecutive weeks of FII net selling has lined up with Nifty drawdowns of about 3–8%. A single day's selling is unreliable on its own.

What does DII buying mean?

It signals domestic institutional confidence and provides a cushion. DIIs are counter-cyclical — they often buy harder when markets dip. Strong DII buying during FII selling ("high absorption") is a stabilising signal that limits downside.

How much FII buying or selling is significant?

Rough guide: under ±₹1,000 Cr is low-impact same-day; ₹2,000–5,000 Cr is noteworthy; above ₹5,000 Cr in either direction often coincides with a 0.5%+ Nifty move. Sustained monthly outflows of ₹50,000 Cr+ have historically driven multi-month corrections.

When is FII DII data published each day?

FII/DII cash provisional figures usually come from NSE/BSE after market close, roughly 4:00–5:30 PM IST. Participant-wise F&O data is typically released around 6:00–6:30 PM IST. NiftyTrader reflects it shortly after the exchanges publish.

Where does the data come from?

The official sources are NSE India and BSE India for daily provisional figures, and SEBI for monthly/quarterly records. This page aggregates that data with daily, monthly and 5-year views, plus FII F&O positioning from NSE's participant-wise OI reports.

How do I read FII DII data for trading?

Check three things: (1) cash net flow direction today, (2) F&O positioning — are FIIs adding longs or shorts, (3) the trend — is this one day or a multi-week streak. One day is noise. Several sessions of heavy selling plus rising index-futures shorts is a real bearish signal — and always cross-check DII absorption before you act.
