What is FII DII data?
FII DII data reports the daily cash-market activity of two groups of institutional investors on the National Stock Exchange: Foreign Institutional Investors (FIIs, a category that now includes all SEBI-registered foreign portfolio investors, or FPIs) and Domestic Institutional Investors (DIIs — mutual funds, insurance companies, pension funds and other domestic pools of capital). For each group and each trading session, the report publishes three numbers in ₹ crore:
- Buy value — gross shares bought by the group across the capital-market segment.
- Sell value — gross shares sold by the group.
- Net figure — buy minus sell. Positive net means the group was a net buyer that day.
Because FIIs and DIIs are the largest disciplined pools of capital in Indian equities, their combined net figures are watched daily as a proxy for institutional conviction — foreign money on one side, domestic money on the other.
Where does the data come from?
The source is the NSE report “FII/FPI & DII trading activity in the capital market segment”, published on nseindia.com after every trading session. Each broker reports its clients' trades to the exchange; NSE aggregates them by investor category and releases the end-of-day totals. The FII DII data page on JustTicks republishes the same end-of-day figures and adds period totals, monthly history, the NIFTY response and CSV export.
| Fact | Detail |
|---|---|
| Segment | NSE capital market (cash/equity) only — not derivatives |
| Frequency | One report per trading session, published end-of-day |
| Units | ₹ crore (1 crore = 10 million rupees) |
| Coverage | All NSE cash-market trades by FIIs/FPIs and DIIs |
How to read a day's FII DII report
Suppose the report shows FII buy ₹12,000 Cr, FII sell ₹13,500 Cr, DII buy ₹11,800 Cr and DII sell ₹10,200 Cr. The net figures are:
FII net = 12,000 − 13,500 = −₹1,500 Cr · DII net = 11,800 − 10,200 = +₹1,600 Cr
FIIs were net sellers and DIIs net buyers, with domestic flows slightly more than absorbing the foreign outflow. Three reading rules keep this honest:
- Net is a small difference of large numbers. Gross values can run above ₹10,000 Cr per side; a net figure is noise unless it is large relative to that base.
- Read both groups together. The FII–DII offset (absorption) plus the NIFTY response tells you whether risk is being redistributed or exited.
- Insist on persistence. Three to five sessions in the same direction carry far more information than any single day's print.
Quick check: FII selling + strong DII buying + NIFTY holding support = absorption. FII selling + weak DII buying + NIFTY breaking down = distribution. The same net number means different things in these two states.
FII vs DII: who they are and how they differ
| Dimension | FII / FPI | DII |
|---|---|---|
| Who | Global funds, sovereign funds, foreign portfolios registered with SEBI | Mutual funds, insurers, pension funds, domestic institutions |
| Mandate | Often benchmarked to India or EM mandates; sensitive to global rates and the dollar | Largely domestic mandates, SIP-driven inflows, insurance premiums |
| Typical behaviour | Faster risk-on/risk-off rotation; leader in selloffs and reversals | Steadier buyers; frequently absorbs FII selling |
| What flows tell you | Foreign appetite for Indian equity risk | Domestic liquidity cushion and support levels |
Their mandates differ enough that the two groups frequently sit on opposite sides: heavy FII selling absorbed by DII buying is one of the most common market-support patterns in Indian equities.

FII DII cash data vs FII derivatives data
The daily FII DII report covers the cash segment only. Foreign institutions also file a separate derivatives report, and NSE publishes FII activity in index futures, stock futures, index options and stock options — buy value, sell value, net and end-of-day open interest, in both ₹ crore and contracts. This is the dataset behind “FII derivatives data” and “FII options data” searches.
- Cash flows answer: did institutions buy or sell stock today?
- Derivatives positioning answers: are institutions carrying long or short exposure, and is it building or unwinding?
A trader reading FII selling in cash alongside rising FII short positioning in index futures reads a very different story from FII selling hedged by long futures. The FII DII data tool shows both tables for the latest session; the participant wise open interest tool extends the derivatives view to all four participant categories.
Limitations and common mistakes
- Aggregates hide strategy. One group's net figure nets off arbitrage, hedging and directional books; you cannot tell a hedged seller from a bear.
- End-of-day only. Figures are definitive only after the session; intraday estimates are projections.
- Stock-specific flows differ. The headline is market-wide; FII DII activity in a specific stock can run the opposite way (see FPI sector data).
- No dataset is a signal. Use flows as confirmation alongside price structure, breadth and volatility — never as a standalone trigger.
