Price is what we all see. Participation is what often explains why the market behaves the way it does.
FII and DII activity doesn’t tell you what to buy or sell. What it does give you is context. It helps you understand whether a move is being supported by participation, whether flows are building over time, or whether the market is stuck in a tug-of-war.
That’s what the FII/DII Activity section inside Analytics is designed to help with.
Who are FIIs and DIIs?
FIIs (Foreign Institutional Investors) are large investment institutions based outside India. These include global mutual funds, pension funds, hedge funds, and sovereign funds. Their decisions are often influenced by global factors such as interest rates, currency movements, and overall risk appetite.
Because of their size, FII activity can have a visible impact on index movement and short-term volatility.
DIIs (Domestic Institutional Investors) are Indian institutions such as mutual funds, insurance companies, and banks. Their investments are typically driven by domestic savings and longer-term allocation strategies.
DIIs often provide stability during volatile periods and can act as a counterbalance when foreign investors turn cautious.
Where to find it
Open Analytics → FII/DII activity on FYERS Web or App.
This section brings institutional participation, index movement, and detailed flow data into one place.
Understanding the dashboard
The top section gives you a quick visual view of institutional flows over time, with controls to set the right context:
Daily, Weekly, Monthly views to change the timeframe
A date range selector (for example, Last 30 days)
A Segment selector to control the type of participation you’re viewing
An index overlay (such as Nifty 50, Sensex, Bank Nifty, Nifty 500)
A Participants filter to view Both FII & DII, FII only, or DII only
This helps you see participation alongside index movement without switching screens.
Cash segment
The Cash view shows institutional buying and selling participation in the cash market.
Rather than focusing on a single day, this section is best used to spot patterns over time:
Sustained participation: Consistent buying or selling over multiple sessions often supports broader market direction.
Divergence: When FIIs and DIIs move in opposite directions, it often explains range-bound or uneven market behaviour.
Context for volatility: Cash participation can help explain why certain moves hold while others fade.
Detailed activity
The lower section breaks participation into more specific views. Here, you can switch between:
Cash provisional
FII cash
MF cash
FII F&O
FII Open Interest
This separation helps you understand not just how much participation there is, but where it is coming from.
FII F&O
For derivatives traders, the FII F&O view adds important context.
It shows how FII participation is distributed across index and stocks, along with buy and sell activity. This is useful when you want to understand whether volatility or trend movement is being accompanied by meaningful derivatives participation.
Open Interest
The FII Open Interest view focuses on positions being carried forward.
This helps answer a different question. Not just what happened today, but whether participation is building or unwinding over time. It’s particularly useful when you’re analysing sustained trends or periods of consolidation.
How to use this without overthinking it
A simple way to use the FII/DII Activity section is to treat it as a context layer:
Use Daily when you want short-term participation context.
Use Weekly or Monthly to understand whether flows are consistently building or fading.
Use Participants to isolate who is driving the move.
Use FII F&O and Open Interest when your focus is derivatives positioning rather than cash activity.
This won’t predict the market, but it will help you read price action with better awareness.
Explore Analytics → FII/DII activity on FYERS Web or App and use it to add institutional context to your market view.
