No credit card required · Trial Plan available · Setup in 3 minutes
OI, FII/DII, PCR, option chain, technical charts, all living on different platforms. By the time you've pieced together a market view, the setup has already moved.
OI on one tab, FII data on another, PCR on a third, price charts in a separate window entirely. Context gets lost every time you switch, and the market doesn't wait around while you reassemble your view from five different places.
A PCR reading means nothing without OI context. An OI spike means nothing without price direction attached. Disconnected data forces you into manual interpretation, and manual interpretation under time pressure is exactly where retail traders make their worst calls.
Most free platforms show NSE data delayed by 15 minutes. In F&O trading, that's often the gap between entering a breakout and buying the top of a move that's already reversed. Real market analysis needs real-time data, which means an NSE-authorised feed rather than a delayed snapshot.
Nifty, BankNifty, FinNifty, and 191 F&O stocks: tracking direction across all of them without one unified platform means fragmented analysis and signals you'll miss. A single view pulling all this together isn't a nice-to-have for serious F&O traders. It's the baseline.
Knowing what each data type actually shows, and how they fit together, is the foundation of informed F&O trading.
Analysis charts take raw market data (OI, price, volume, PCR, institutional flows) and turn it into something you can actually read. For F&O traders, that structure is what lets you form a view on direction before committing capital. Stolo covers 20+ chart types in one platform, all updated in real time from NSE.
Open Interest tracks committed money, not just transacted money. A rising OI chart shows you which direction institutions are building positions in, often before price gets around to confirming it. Between the option chain, strikewise OI, multi-strike OI, and OI charts, Stolo gives you a real-time read on where the large money actually sits across every F&O instrument.
Foreign and Domestic Institutional Investors move markets. When FIIs aggressively build or exit index future positions, Nifty and BankNifty follow. Stolo's FII/DII tracker gives you this data in real time during market hours, letting you align your options strategy with institutional flows rather than trade blindly against them.
No single chart gives you the full picture. The option chain shows where money is positioned, the PCR chart shows sentiment, TradingView gives price context, FII/DII gives institutional direction. Professional F&O traders build their market view by pulling all four together, in one place, without hopping between tabs to do it.
Market data, OI analysis, technical charts, and institutional flows: everything an F&O trader actually needs, in one place.

Start AnalysingBefore you look at anything else, check Stolo's FII/DII tracker. Net buying by FIIs in index futures usually means the broader market has institutional tailwind for the session; heavy selling shifts the bias the other way. This is worth doing first because it colours how you read every chart that follows, not just one of them.
Open the option chain for Nifty or BankNifty and find the strikes with the heaviest call writing and put writing. Those strikes mark out the session's likely range: heavy call OI is resistance, heavy put OI is support. These levels tend to hold up better than pure price-pattern levels, simply because they're backed by actual committed capital rather than a chart pattern from last week.
Pull up the PCR chart and see where the ratio sits against its recent range. Above 1.2 usually means more put writing, which points to a bullish tilt among option writers expecting the market to hold or rise; a low reading suggests the opposite view from the same crowd. This is what tells you whether to lean into directional trades or expect a range-bound day.
With an OI-backed level and a sentiment read from PCR in hand, switch to the TradingView chart for the instrument. Watch for price approaching that OI-identified level, then use a technical trigger, a candlestick pattern, a moving average cross, a volume spike, whatever fits, to time the actual entry. OI gives you the zone; the chart gives you the moment.
Once you're in the trade, keep Stolo's live market data views open: sector movements, top gainers/losers, OI changes, whatever tells you the market is still moving the way you expected. Falling OI on your instrument while you're holding a position is an early sign that participants are heading out. Check it against Stolo's OI analysis tools so you're ahead of a reversal instead of reacting to it after price has already moved.

Four data dimensions that, together, give you a market view no single chart type can provide on its own.
OI tells you how many contracts are outstanding at each strike, and how that number is moving. Watch it build at a specific strike and you've found a support or resistance zone with actual traders behind it, not just a line someone drew on a chart. Across option chain, multi-strike OI, strikewise OI, and OI charts, Stolo shows you where that institutional money actually sits, live, on Nifty, BankNifty, FinNifty, and all 191 F&O stocks.
Foreign and Domestic Institutional Investors move this market more than any retail crowd does, and heavy FII buying or selling in index futures usually drags Nifty and BankNifty along with it. Stolo's FII/DII tracker gives you daily derivatives and capital market data, live during market hours rather than as a next-day summary, so you can position with that flow instead of fighting it.
The Put-Call Ratio is one of the steadier sentiment indicators in options trading. Skewed high, it points to more put writing and a bullish tilt; skewed low, the opposite. Stolo's live PCR charts track this alongside price and OI, and pairing it with Stolo's own Options Snapshot tool catches large OI shifts before they move the market, usually before most retail traders have even noticed.
No trade happens in isolation, even though it's tempting to analyse it that way. Stolo's sectoral indices view shows which sectors are leading or lagging, giving you macro context before you place an options trade. Add in the top gainers/losers and market movers views and you get a full-market read, so you're not making a call on one instrument's chart while missing a sector-wide move happening around it.
