What is OI Interpretation in Options Analytics?

OI Interpretation in Options Analytics helps you understand how option strike prices and Open Interest (OI) are behaving together for a selected underlying and expiry. Instead of analysing raw OI numbers, it classifies strikes into clear market conditions so you can quickly identify whether positions are being built or exited — and on which side.

This feature is available on FYERS Web and the FYERS App.

What does OI Interpretation show?

OI Interpretation displays option strikes of the selected underlying and expiry that meet specific price–OI behaviour conditions during the selected time interval. Each strike is grouped into one of the following categories:

Category	Price movement	Open Interest movement	What it typically indicates
Long build-up	Increasing	Increasing	New long positions are being created
Long unwinding	Decreasing	Decreasing	Existing long positions are being closed
Short build-up	Decreasing	Increasing	New short positions are being created
Short covering	Increasing	Decreasing	Existing short positions are being closed

OI Interpretation reflects changes in price and Open Interest for the selected interval. It indicates position activity, not guaranteed market direction. Always use it along with other analysis tools.

How to access OI Interpretation

On FYERS Web

Go to Options
Select Analytics
Open OI statistics
Click OI Interpretation
Choose the underlying, expiry, and time interval

On FYERS App

Go to Options
Tap Analytics
Select OI statistics
Tap OI Interpretation
Choose the underlying, expiry, and interval

Example

If a selected option strike shows a rise in price along with an increase in Open Interest during the chosen interval, it will appear under Long build-up.

Similarly, if price falls while Open Interest increases, it will be classified under Short build-up.

What if no strikes appear?

Ensure you have selected the correct expiry and time interval.
Some intervals may not show classifications if price and OI changes do not meet the defined conditions.
Illiquid strikes may not generate meaningful OI movement.
