NIFTY Multi-Strike Open Interest | Live OI Across Strikes
The multi-strike OI view for NIFTY shows open interest for several strikes on a single chart — the total OI footprint across the option chain instead of one strike at a time. This makes it easy to see how institutional positioning is distributed acrossNIFTY strikes: concentrated buildups reveal where writers are defending key levels, while OI unwinding across adjacent strikes signals that a directional move may be brewing as institutions exit structured positions.
Every strike's OI curve for NIFTY can be added, removed, or hidden, so you can focus on just the ATM band, the full ±5% range around spot, or specific far-OTM strikes you're watching for tail-risk hedging activity. You can track both total OI and OI change (the more important series for intraday reads), across all active expiries. Weekly expiries usually show faster, more reactive flows; monthly expiries show deeper institutional commitment in NIFTY option chains.
Reading the NIFTY multi-strike OI footprint
A heavy OI cluster at a NIFTY strike that's also showing rising total OI is a strong support or resistance reading — institutions are willing to sell more premium there, confident the strike will hold. When the cluster starts shedding OI (positive spot move into the strike but OI dropping), that's the classic unwinding signature that often precedes a breakout on NIFTY. The multi-strike view makes it obvious when this is happening at one strike or spreading across several. Live mode keeps each strike's OI updated across the NSE session.

How to use Multistrike OI
- Pick an underlying and expiry — Choose Nifty, BankNifty, or an F&O stock and select the expiry you want to analyze.
- Set the strike range — By default the view shows ATM ± 5 strikes. Widen the range if you want to see resistance/support strikes that are far from current price.
- Identify peaks in call and put OI — Look for the strike(s) where call OI and put OI both peak — these are the candidate pinning levels for the expiry.
- Watch OI shifts in real time — As the session progresses, monitor which strikes are gaining or losing OI. Migration up the ladder = bullish; down the ladder = bearish.
- Combine with Max Pain — Cross-reference the multistrike OI peak strike with the live max pain strike. When they agree, the pinning thesis is strongest.
