Multistrike OI is a chart view that plots open interest changes for multiple strikes simultaneously, usually centered around the at-the-money strike. Instead of looking at one strike in isolation, you see the entire range of OI activity in one frame — making it much easier to spot expiry pinning, breakout setups, and the boundaries of the market's expected move. ### How does comparing OI across multiple strikes help find expiry pinning? When the underlying approaches a strike with very high call AND put OI, writers from both sides have an incentive to defend that level. The combined hedging activity can 'pin' the price to that strike through expiry. Multistrike OI lets you spot the candidate pinning strike days in advance by visualizing where call OI and put OI peak together. ### What strikes should I watch for Nifty intraday? Watch the strikes with the highest call OI (resistance), highest put OI (support), and the ATM ± 2 strikes (where intraday positioning concentrates). The StockMojo multistrike view defaults to showing this range. As Nifty drifts during the day, OI changes at these strikes are the most actionable intraday signal. ### How does OI shift across strikes confirm a breakout? A genuine breakout is usually preceded by OI being added at strikes above the prior resistance — call OI shifting higher signals fresh long positioning by call buyers (or short covering by call writers). Multistrike OI makes this rotation visible at a glance: you see the OI wave moving up the strike ladder as the breakout develops. ### What's the difference between multistrike OI and the option chain? The option chain shows every strike's OI as a row in a table. Multistrike OI shows multiple strikes' OI changes as overlaid time series in a single chart. The chain is better for absolute readings; the multistrike view is better for spotting how OI is migrating across strikes over time — which is the actionable signal for intraday traders. ### Can multistrike OI predict expiry day moves? It can suggest the most likely pinning candidate, but the prediction isn't precise. On Nifty weeklies, the pinning strike identified by multistrike OI in the morning of expiry day proves correct (within one strike) about 60-65% of the time. That's an edge, not a certainty. Always confirm with price action and use stop losses. ### How frequently should I refresh multistrike OI charts? During market hours the StockMojo chart refreshes on the same NSE cadence as the option chain, every 1-3 seconds. Active intraday traders typically watch it continuously; positional traders check it at the open, midday, and 30 minutes before the close. Refreshing more often doesn't reveal more — it just adds noise. ### How is multistrike OI used by institutional traders? Institutions use multistrike OI to size their hedging activity and to identify which strikes to defend. A desk that has written a large amount of OI at a particular strike will hedge dynamically as the underlying approaches that strike, contributing to the gravitational behavior the multistrike chart reveals. Retail traders can essentially see institutional defense lines forming in real time. ## How to use Multistrike OI 1. **Pick an underlying and expiry** — Choose Nifty, BankNifty, or an F&O stock and select the expiry you want to analyze. 2. **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. 3. **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. 4. **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. 5. **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. ## Related tools - [Open Interest](https://stockmojo.in/open-interest) — markdown: https://stockmojo.in/open-interest.md - [Option Chain](https://stockmojo.in/option-chain) — markdown: https://stockmojo.in/option-chain.md - [Max Pain](https://stockmojo.in/max-pain) — markdown: https://stockmojo.in/max-pain.md ## Glossary Terms used: open-interest, strike-price, expiry, max-pain.
