FII and DII Activity: Track Institutional Flows
The index moves where the big money pushes it. FII and DII activity in Stolo shows what the largest participants, foreign and domestic institutions, plus retail and proprietary traders, did each session across the cash and derivatives segments. Reading that flow tells you who is in control and which way to lean before the next open.
The problem it solves
The price chart shows the result of institutional flow but not the flow itself. A flat day can hide FIIs quietly building a large short in index futures while DIIs absorb their cash selling. That divergence is the story, and you only see it in the participant data. This view puts the cash and derivative flows for every group in one place.
The concept
- Institutions set the trend. FIIs and DIIs trade in size and their net direction usually leads the index over days and weeks.
- Cash and derivatives together. Cash buying with a futures short is a hedge; cash selling with a futures short is a genuine bearish bet.
- Absorption matters. FII selling met by DII buying holds up; FII selling met by DII selling does not.
- Retail is often the other side. At extremes, heavy retail positioning against the institutions can mark a turn.
Key terms explained

|---|---|
| FII | Foreign Institutional Investors. |
| DII | Domestic Institutional Investors: mutual funds, insurers, banks. |
| Pro / proprietary | Broking firms trading their own capital. |
| Net cash flow | Buy value minus sell value in the cash market for the day, in crore. |
| Participant-wise OI | End-of-day open interest by participant group in each derivatives segment. |
| Long-short ratio | Long contracts divided by short contracts for a group in a segment. |
A worked example
After the close you check the FII and DII activity view.
- Cash: FIIs net sellers of 2,800 crore, DIIs net buyers of 3,100 crore. Selling absorbed.
- Index futures: FIIs added 18,000 net short contracts; their long-short ratio dropped from 1.1 to 0.85.
- Index options: FIIs net bought puts.
The read: FIIs turned meaningfully bearish on the index today, but domestic funds are holding the cash market up. The next session, you lean short on rallies but respect that a hard fall may be cushioned by the DII bid. If the following day FIIs cover that short, the bias flips back.

info
This is a daily, after-the-close read that frames your bias. It does not time an entry. Stolo does not place trades.
How traders use it
- Next-day bias. A large fresh FII index short plus heavy cash selling means lean bearish tomorrow.
- Absorption check. Judge how much support a falling market has from the DII bid.
- Trend confirmation. Several days of consistent FII buying supports staying long.
- Contrarian flag. Extreme retail positioning against the institutions questions a stretched move.
Frequently asked questions
What are FII and DII?
FII stands for Foreign Institutional Investors, the overseas funds that trade Indian equities and derivatives. DII stands for Domestic Institutional Investors, the Indian mutual funds, insurers and banks. Together they are the largest players in the market, and the direction of their net buying or selling often sets the trend for the index.
What does the FII and DII activity view in Stolo show?
It shows participant-wise activity for FIIs, DIIs, retail and proprietary traders across the cash market and the derivatives segments. That includes net cash buying or selling and the net positioning in index futures, index options, stock futures and stock options, so you see not just how much each group traded but which way they are leaning.
Why does it matter when FIIs sell but DIIs buy?
It tells you the selling is being absorbed. A day where FIIs are net sellers of 3,000 crore in cash while DIIs buy 3,200 crore usually holds up better than one where both are selling, because the domestic bid is supporting the market. When both sides sell together, there is no absorption and falls tend to be sharper.
What is the FII index futures long-short ratio?
It is the number of long index futures contracts FIIs hold divided by their short contracts. A ratio well above 1 means FIIs are net long the index and positioned bullishly; well below 1 means they are net short. A sharp change in the ratio day to day is a stronger signal than the level itself.
How often is FII and DII data updated?
The cash market provisional figures come out after the close each day, with final numbers the next morning. The participant-wise derivatives data is an end-of-day figure. So this is a daily read you check after the session, not an intraday tool.
How do I use FII and DII data with an intraday trade?
Use it to set your bias for the next session. If FIIs added a large net short in index futures and sold cash heavily, start the next day leaning bearish and treat rallies as selling opportunities until the flow changes. It frames the day rather than timing an entry.
What does heavy retail activity on one side tell me?
Retail positioning is often read as a contrarian signal at extremes. When retail is heavily net long index options into a rally, or heavily net short into a fall, it can mark a point where the crowd is offside. It is a weak signal on its own and best used to question a move that already looks stretched.
Can I see the historical trend of FII and DII flows?
Yes. The view shows the running trend over recent sessions, so you can see whether FIIs have been consistent net buyers for a fortnight or have just flipped to selling. A multi-day trend is a stronger background signal than any single day.
Where does the data come from?
From the exchange and depository disclosures: the NSE and BSE cash market participant figures and the exchange's participant-wise open interest report for the derivatives segment. Stolo consolidates these into one view.
