Multi-Strike OI Chart Today | Compare Multiple Strike OI Live
Analyze multi-strike open interest (OI) trends for Nifty, BankNifty, and all NSE F&O stocks. The Multi-Strike OI tool by StockMojo allows you to overlay OI data for several strike prices on a single interactive chart for deep market analysis.
Track how institutional positions are evolving across multiple price levels in real-time. By visualizing the OI trend of different strikes together, you can identify roll-overs, hedging activities, and potential breakout zones more effectively than with standard OI charts. Monitor live intra-day shifts or dive into historical patterns to build a data-driven trading strategy.
Why Compare OI Across Multiple Strikes
Standard OI charts show data for a single strike at a time, which limits your perspective. In practice, institutional traders spread their positions across multiple strikes. A market maker selling a straddle at the 24,200 strike might simultaneously sell strangles at 24,000 and 24,400 as a hedge. A directional fund building a bearish position might write calls at 24,300, 24,400, and 24,500 simultaneously. By viewing OI trends for five to ten strikes on a single chart, you can see the full picture of how positioning is distributed and evolving throughout the day.
The multi-strike view also reveals position roll-overs. If OI at the 24,200 CE is declining while OI at the 24,300 CE is increasing at a similar rate, call sellers are rolling their resistance level higher, which is a bullish signal. Without comparing multiple strikes simultaneously, such roll-overs are easy to miss.
Identifying Resistance and Support Walls
A resistance wall forms when Call OI accumulates heavily at a cluster of adjacent strikes. For instance, if 24,400 CE, 24,450 CE, and 24,500 CE all show OI above 30 lakh contracts each, there is a strong resistance wall between 24,400 and 24,500. Nifty breaking above this zone requires significant buying pressure to force call sellers into covering their positions. The multi-strike chart makes these walls visually obvious: you see multiple overlapping lines rising together in a tight band.
Similarly, a support wall forms when Put OI is concentrated at adjacent put strikes. If 23,800 PE, 23,850 PE, and 23,900 PE all show heavy OI accumulation, a strong support zone exists between 23,800 and 23,900. When OI at one of these strikes starts declining while the others hold steady, it suggests the outer edge of the support wall is weakening and the effective support may shift inward. This granularity is only visible through multi-strike comparison.
Tracking Institutional Activity Intraday
Institutional traders on the NSE tend to build positions in the first two hours of trading (9:15 AM to 11:30 AM) and adjust in the last hour (2:30 PM to 3:30 PM). Using the multi-strike OI chart, you can observe whether institutions are widening or narrowing their strike range. If early in the session OI was spread between 24,000 and 24,400 but by afternoon it concentrates between 24,100 and 24,300, the expected range for expiry is narrowing. This insight is valuable for straddle and strangle sellers who profit from range-bound markets.
On expiry Thursdays for Nifty weekly options, the multi-strike chart becomes especially useful because OI unwinds rapidly at out-of-the-money strikes while in-the-money strikes may see new OI from gamma hedging. Monitoring these shifts in real-time helps scalpers and expiry-day traders identify the likely settlement zone.

Nifty 50 (NIFTY) Multi-Strike OI: Custom Strike Selection
Why choose strikes manually instead of auto-selection?
Default strike selection on multi-strike tools usually picks strikes around ATM. That works well as a starting point, but manual selection lets you focus on the exact strikes that matter for your trade. If your Nifty 50 trade thesis focuses on specific support and resistance levels, pick those strikes. If you are watching a specific breakout zone, pick strikes around it. Custom selection turns the tool into a focused dashboard for your particular view.
How many NIFTY strikes should you track?
For most traders, 5-8 strikes is the sweet spot. Fewer than 5 misses important context. More than 10 becomes cluttered and hard to read. Pick 2-3 strikes above your current NIFTY price (resistance watch), 2-3 strikes below (support watch), and possibly the ATM strike itself. This balanced selection gives you a complete view of the nearby options landscape without overwhelming the chart.
Adjusting strike selection as NIFTY moves
Your selected strikes become less relevant as Nifty 50 price moves away from them. If you picked strikes centred on 22500 and NIFTY is now trading near 22800, your selection is stale. Update your strike list to centre on 22800. Good traders rebalance their multi-strike selection at least once a day — more often during trending sessions. This discipline keeps the tool aligned with current price action.
Saving NIFTY strike selections for different setups
Different trade setups benefit from different strike selections. A breakout watch might pick strikes above the current range. A support test might pick strikes below. A pinning setup for expiry day might pick the strikes closest to the expected max pain. Rather than re-selecting every time, think about your common setups and pre-define the strike groups you use. As of 16 May 2026, this preparation speeds up your live analysis and prevents rushed decisions in fast markets.
Nifty 50 (NIFTY) Multi-Strike OI: Identifying Unusual Activity
What counts as unusual OI activity on NIFTY?
Unusual activity is when OI at a specific strike suddenly grows much faster than the market's overall pace. For Nifty 50, a normal OI change might be a few thousand contracts. Unusual activity could be 50,000+ contracts in a single session at a strike that was previously quiet. The multi-strike view makes spotting unusual activity easy — any strike whose line is climbing faster than others stands out immediately.
What does unusual activity on NIFTY signal?
Unusual activity is often a fingerprint of informed traders — institutions or insiders making a confident bet. When you spot a strike with unusually aggressive OI growth, something is likely happening behind the scenes. Maybe an event is expected. Maybe a large trader knows something you do not. Maybe a hedge is being built. The signal is not always interpretable, but it is worth paying attention to.
Filtering false alarms on NIFTY unusual activity
Not every OI spike is a real signal. Some are: block trades that happen at month-end (portfolio rebalancing, not direction), errors in data feeds (unusual but meaningless), or retail pile-ons on popular news events (retail is often wrong). Filter for institutional-style activity: sustained rather than one-shot, near-ATM rather than far-OTM, and accompanied by reasonable volume. As of 16 May 2026, these filters screen out most false signals.
Responding to NIFTY unusual activity
When you spot genuine unusual activity, do not blindly follow. Investigate: what event might be coming? What is the directional implication of the activity (calls or puts, ITM or OTM)? Cross-reference with news and other tools. If the picture is clear, consider a small directional position aligned with the activity. If it is unclear, simply note the pattern and watch for follow-through in the next 1-2 sessions. Information from multi-strike OI is worth more when processed thoughtfully.
Frequently Asked Questions
What is multistrike OI analysis?
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
- 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.
