What if I told you, you can see what the big players are doing in the market?
And what if I told you, you can do this for free?
Well, with the new revamped FII DII Page, you can do just that & more. We made our FII DII Page easier to understand and added more data points for precision analysis.
All this and more, completely free of cost!
We have made a detailed video on how to interpret this data and make sense of it. You can watch it here. Alternatively, you can continue reading this blog 🙂
By following the big players in the market you can easily understand where the market is heading.
But who are these big players?
They are:
1. FII – Foreign Institutional Investors. They include prop firms, hedge funds, investment banks, pension funds, etc.
2. Pro – Trading firms with broking membership who trade with their funds. This could also be brokers who trade with their own money.
3. Client – This refers to all the trades done through brokers. A common misconception is that this data is purely retail. That is not true. It includes HNIs, small funds, companies, trading desks, etc.
4. DII – Domestic Institutional Investors. Mainly Asset Management Companies that invest in Mutual funds. They are not very active in F&O.
You can read more about them and learn how to interpret their data in the tooltip attached to the feature.
Now let’s understand how to make sense of the data shown on the Summary Page
On this page you’ll see the data of one day. You’ll see here what activity was done by all participants on that particular day. You can see the data of FII, Pro, and Client in Index Futures and Index Options.
If you expand the data of FIIs in Index Futures you can see data segregated into different indices, NIFTY, BANKNIFTY, MIDCAPNIFTY and FINNIFTY. This segregation is only for FIIs.
Let’s first understand how to read the Index Futures data:
- On the below image, you can see both Net OI and OI change made on a particular date by FII’s and the strength is derived based on the combination of net OI and Change in OI
- If Strength is Bullish, then it means FII’s are Bullish on the market
- If Strength is Bearish, then it means FII’s are Bearish on the market
- If Net OI and Change in OI are opposite, then it will be indecisive. Means we can’t predict any sentiment for that day

- For other participants, you’ll only see the net figures in the Futures section

Now, lets look at Index Options data:
- When you expand the tab you can see the split in OI by Call and Put Options
- For us the Net Options strength is important.
- If it says Bullish then participants are bullish today in options
- If it says Bearish then participants are bearish today in Options
- If it says Neutral then participants are expecting a range bound market
- If it says Volatile then participants are expecting a big swing on any side
- Net options strength is calculated using Call and Put options strength combined
You can go back in date using the arrow button on the top or you can select any date by using the calendar. Here you’ll get the data of past 30 days
On the right you can see the filters where you can select to see other data like DII, Stock Futures, & Stock Options.
Now let’s move on to the next page, the Futures and Options page:
Here you’ll see four graphs. In all four graphs, you can see the data for the last 30 days. And if you want to see the activity for the previous month then you can simply select it from the drop-down on the top right corner.
The first graph here is Daily FII Buy/Sell in Index Options.

Here you’ll see the daily activity of FIIs in the Options Segment.
If you want to understand how to read this data then you can click on the “How to read this?” tooltip
If you want to see the Long and Short OI of Call and Put options then you can turn ON this toggle from here and now you’ll be able to see the Long and Short OI in the tooltip.
The second graph is the Daily FII Buy/Sell in Index Futures:

This graph tells you the daily activity of FIIs in the futures segment.
If you want to understand how to read this data then you can click on the “How to read this?” text as shown earlier.
In the chart setting section you can select:
- To view daily change by Amount or Quantity
- You can select to view activity in NIFTY, BANKNIFTY, Show all indices separately or cumulatively
The third graph here is FII OI in Index Options:

This graph provides the FII’s Outstanding Open interest in Options. Here if calls are more than Puts (green bar is bigger than red bar) then we can say the FII are bullish on the market.
And if puts are more than Calls (Red bar is bigger than green bar) then we can say FIIs are bearish and are expecting the market to go down.
But, please note that most of the time, the red bars are bigger than the green bars. It does not mean the market is bearish. That’s because Puts will always be in demand for hedging purposes.
To understand how to read this, you can refer to the ‘How to read this?’ tooltip where all different scenarios are explained clearly.
The fourth graph here is FII OI in Index Futures:

This graph tells you what is the net open OI of FII in Futures. Where they are net short or net buyers in the market.
A positive number means FIIs are net long, and a negative number means they are net short. However, if they are long, it does not always mean the market will go up. And if they are short, it does not always mean the market will go down.
To understand how to read this, you can refer to the ‘How to read this’ tooltip
You can see these four graphs for DII, Pro and Client.
Here are some points to note about them:
- DII: They don’t have much activity in the F&O segment
- Pro: All the graph interpretations will be similar to FII.
- Only in the Daily Pro Buy/Sell in Index Futures graph the Futures activity is shown for cumulative indices
- Client: Since we know the clients are usually wrong in the market. So, the interpretation of the graph here will be the opposite of their position. So,
- If they show bullish activity then we’ll interpret market can go down
- If they show bearish activity then we’ll interpret market can go up
In any kind of confusion, you can always visit the ‘How to read this’ tooltip.
Moving on to the next page, Cash Market
On this page, you can see the Cash market activity of FIIs and DIIs in the graphical and tabular form.
However, cash market activity is not useful in F&O trading.
To understand how to read this, you can refer to the ‘How to read this’ tooltip
Here if you want to see the cash activity on a Daily or Monthly basis, you can use the switch it here. If you want to see the activity of any past month you can select it from the drop-down menu.
Coming to the last page of FII DII data, FII History
We know some people are more comfortable reading the data in tabular form. So, on this page you can find the FII activity history of Options, Futures and Cash in tabular form. You can choose to see historical data for any month with the help of the dropdown.
Other Enhancements
You can track the change in strength from yesterday to today by hitting on the “Replay” button.
Also, you can see the close values for NIFTY and BANKNIFTY to understand how the market performed on the selected date and the next date.
Apart from this, you can track the Change in OI, and Net OI of FII, DII, & Client side by side for better understanding.
And we know that staring at the white screen for a long time is very difficult so we have added the dark mode in the FII DII data page.
So what are you waiting for?
