India’s Ultimate Multistrike OI Analysis Tool - Take your options trading to the next level with Stolo's Multistrike OI Analysis tool, offering comprehensive data and analysis for informed decision-making.
No credit card required · Trial Plan available · Setup in 3 minutes
Options markets move on institutional positioning — but most traders only watch one strike at a time. That is the analytical gap that costs them trades they should have won.
When you watch only the ATM strike, adjacent OI walls stay invisible. A resistance level three strikes away can stop a breakout you never saw coming — and you take a loss on a trade that had no business being entered.
By the time a breakout is confirmed on the price chart, the OI signal that predicted it fired 10 minutes earlier. Single-strike tools leave you perpetually one step behind the institutional move.
Checking five strikes across two expiries means five tabs, constant refreshing, and a fragmented picture. Under intraday time pressure, this fragmentation is exactly where decision errors happen.
Large OI unwinds at key strikes are the earliest warning that a support or resistance level is breaking. If you are not watching multiple strikes live, these signals disappear before you can act on them.
Multistrike open interest is the practice of tracking OI data across multiple strike prices simultaneously — giving traders a panoramic view of where institutional money is positioned.
Open interest is the total number of outstanding options contracts that have not been closed or expired. It is cumulative — when new contracts are created, OI rises; when positions close, OI falls. High OI at a strike means significant institutional capital is committed at that level.
Single-strike OI tells you about one price level. Multistrike OI tells you the story of the entire range. You see where writers are concentrated, where coverage is thin, and which levels institutions are actively defending — information that simply does not exist when you look at one strike at a time.
Strikes with very high Call OI act as resistance — option writers there will defend the level. Strikes with very high Put OI act as support. Markets tend to gravitate toward these OI clusters and then reverse or break through them. Multistrike OI makes these walls immediately visible.
The difference between Call OI and Put OI across the range reveals whether the market is positioned bullish or bearish at each strike. Seeing this balance live — for up to 30 strikes simultaneously — shows you the true conviction behind a price move before it fully develops on the chart.
Every feature is designed for the trader who needs to read the options market — not just glance at it.
Track live LTP, OI, OI change and volume for multiple strike prices simultaneously — across Nifty, BankNifty and FinNifty — without switching tabs or refreshing charts.
Select up to 3 expiry dates — weekly, monthly or far month — and compare OI across expiries to understand where institutions are rolling positions and placing long-term bets.
Run multistrike OI analysis not just on indices but across all 191 NSE F&O stocks — spot accumulation, distribution and range compression in individual stocks before entering positions.
Select any 30 strikes above and below the ATM price for a wide-angle view of the OI landscape — critical for understanding the full range of institutional positioning in any expiry.
Watch OI build-up and unwind in real time across selected strikes. Live charts refresh continuously during market hours so you catch institutional moves as they happen, not after the fact.
View absolute OI, OI change, Call vs Put OI and net OI across up to 30 strikes at once — giving you the full picture of where writers are concentrated and where the market is likely to gravitate.
Toggle between Call (CE) and Put (PE) OI for any strike price independently — isolate writer positioning on either side and spot asymmetric risk before it shows on the price chart.
Overlay index price, multiple Call OI lines and multiple Put OI lines on a single chart — see exactly how price is reacting to OI levels in real time, without jumping between windows.
High open interest at a strike price is the market marking a battleground. Where Call writers congregate becomes resistance — where Put writers pile in becomes support. Stolo lets you view up to 30 strikes simultaneously, making these OI walls immediately visible.
Instead of guessing levels from candlestick patterns, you read them directly from real-time institutional positioning — giving you high-confidence targets for your options strategies.
Try It Free
For traders running straddles, strangles or ratio spreads, watching OI shifts across strikes away from ATM tells you when the market is likely to breach a range — so you can adjust hedges before the move, not after.
With 30 strikes in view simultaneously, you are never caught on the wrong side of a large OI unwind in Nifty or BankNifty. The signal is already there — most traders just cannot see it.
Start Free TrialThe biggest mistake in options trading is picking a strike based on premium alone. Multistrike OI analysis shows you which strikes have the strongest writer interest — meaning the market expects price to stay away from them.
Sell near high-OI strikes where writers are defending. Buy where OI is thin and momentum is building. Stolo's real-time charts make this analysis fast enough to act on before the opportunity closes.
See It in Action
A systematic pre-trade OI check takes under two minutes and dramatically improves strike selection. Here is the process serious traders follow before every trade.
Start FreeChoose your index — Nifty, BankNifty or FinNifty — or one of the 191 F&O stocks, then select up to three expiry dates. Start with the nearest weekly expiry for intraday trades. Add a monthly expiry when you are analysing positional setups or rolling risk.
Select the ATM strike plus 5 to 10 strikes above and below. For wider-ranging instruments like BankNifty during volatile sessions, go deeper. Stolo highlights ATM automatically so your range is correctly anchored from the start without manual calculation.
Look for the strikes with the highest Call OI (resistance wall) and the highest Put OI (support wall). These become your reference range for the session. Any approach to these walls is a potential reversal or breakout point — watch them closely as price moves toward them.
Watch the OI change column continuously. A rapid unwind at the Call wall means writers are losing conviction and a breakout may be building. Stable OI at the Put wall while price tests it confirms strong support. Acting on the signal as it forms — not after it confirms on the chart — is where the edge lives.
Before executing, cross-check your multistrike OI reading with Stolo's open interest analysis tool to confirm the broader OI trend aligns with what the multistrike view is showing. When both tell the same directional story, your trade has stronger evidence behind it and a higher probability of playing out as expected.
See why tracking open interest across multiple strikes gives you a fundamentally different — and more actionable — view of the market than standard tools.

Multistrike OI is the fastest way to read institutional positioning across the full options range — not just one strike at a time.
Viewing one strike at a time is like reading a map one square inch at a time. Multistrike OI gives you the full picture — up to 30 strikes, live CE and PE OI, real-time chart overlays — so you can read the entire options chain story in one consolidated view without switching screens.
Watch OI shifts across strikes away from ATM in real time. When large OI unwinds at a key strike, it is an early warning that support or resistance is breaking — giving you time to adjust stops, exit or hedge before the damage reaches your P&L.
When OI clustering is visible at multiple strikes simultaneously, high-probability setups become obvious — range-bound markets for premium selling, OI wall breaks for directional plays, and cross-strike divergences for spreads. Stolo puts all of this in front of you in real time.
