Market Intelligence

Read what the market is actually doing, not just where price went

Price alone tells you where the market went. Open interest tells you where money is positioned. Stolo surfaces OI data, PCR trends, and institutional flow in real time, sourced directly from NSE. No scraping, no approximations.

  • Live OI refresh every 3 minutes: NSE-authorised data, not a scraped estimate
  • 50+ analysis charts: OI buildup, PCR, Max Pain, gamma, IV surface, FII/DII flow
  • Multi-strike OI view: the full option table at a glance, not one strike at a time
  • Historical OI data: compare current positioning against past expiry patterns

Strategy Builder

Know your risk before you place the trade, not after

Most traders discover the full risk of a position only when it starts moving against them. Stolo's strategy builder shows your payoff curve, breakeven points, and max loss in seconds, for any multi-leg combination, on any expiry.

  • Multi-leg builder: construct straddles, condors, spreads, and custom combos
  • Live payoff curve: watch profit and loss shift at every price point as the market moves
  • Greeks on every leg: delta, gamma, theta, vega, calculated in real time
  • One-click execution: place the entire strategy from the builder without retyping every leg

The Workflow

Read. Execute. Reflect.

Three stages, one platform. Stolo is the only tool you need from the time you open your first chart to the moment you review your last trade of the session.

Start with Trial
01

Read the market before your first trade

Open the OI analysis charts, check PCR trend, and identify the key strikes for the current expiry. This 5-minute pre-market read gives every scalp a structural foundation instead of a reactive guess based on price alone.

02

Execute from the terminal without switching apps

Connect your broker and place orders, manage stops, and trail positions directly from within Stolo. Keyboard shortcuts and predefined rules mean your parameters are always set before you click buy. No app-switching, no delays during a fast move.

03

Review every trade and close the learning loop

After the session, the order analysis module shows every trade with entry timing, exit quality, and P&L relative to your stop and target. The journal lets you annotate each decision. Over weeks, this review practice builds a pattern-recognition edge that no indicator can replace.

One platform, four trading styles. Pick yours, and Stolo surfaces what matters most for it.

Scalper

The Scalper

In and out in minutes. You need live OI, a keyboard-shortcut terminal, predefined order rules, and an exit that fires at the speed your move deserves, not the speed of your mouse.

You hold for hours, not minutes. OI trend confirmation, PCR reversal signals, and the option chain are your pre-trade checklist. Stolo surfaces all three in one dashboard, so there's no tab-switching between tools.

My first impression of your site, "K.I.S.S." — Simple yet effective. Uncluttered and has all the ingredients a trader actually needs, not the nonsensical ones. Great job.

You have something unique in your platform that has changed my trading. I have used Quantsapp earlier — didn't find it useful. I have tried Opstra, Sensibull etc. Nothing compares.

I am really impressed with the user interface and multiple other facilities for option traders. The OI charts alone are worth the subscription — I have not seen this level of clarity anywhere else.

Ask in Telegram
What is Stolo and who is it built for?
Stolo is an options trading intelligence platform built for NSE retail traders in India. It brings together real-time OI data, 50+ analysis charts, a multi-leg strategy builder, a broker-integrated terminal, and post-trade review tools in one place. Scalpers, day traders, options sellers, and anyone who wants decisions backed by data rather than gut feel tend to end up here. One thing worth flagging: Stolo is not a broker. It plugs into the broker account you already have and adds the analytical layer that account is missing.
What makes Stolo different from Sensibull, Opstra, or Quantsapp?
Most tools in this space do one job well. Sensibull is built around strategy visualisation. Opstra and Quantsapp are built around OI data. Stolo tries to cover the whole trading day in one workflow: analyse the market, build the strategy, execute the trade from the same screen, and review it in the journal afterward, all connected to your broker. The OI data itself comes straight from NSE, not scraped, and refreshes every 3 minutes.
How does Stolo connect to my broker?
Stolo works with 10+ Indian brokers, including Zerodha, Upstox, Angel One, Dhan, and Fyers. Setup takes under 3 minutes: head to the Brokers section in Settings, pick your broker, and authenticate through OAuth, the same standard your bank uses for third-party apps, so Stolo never stores your login credentials. Once that is done, your live portfolio, positions, and order book show up inside Stolo, and you can place orders directly from there.
Is Stolo's OI data sourced directly from NSE?
Yes. Stolo is NSE-authorised, so the OI numbers come straight from the exchange rather than being scraped from third-party sites or estimated from trade data. That matters more than it sounds: scraped OI can lag by 10-30 minutes or throw errors during volatile sessions, which is exactly when you need it most. Stolo refreshes every 3 minutes through market hours, so you are working off the same numbers the market is actually pricing from.
Does Stolo work for both Nifty and BankNifty options?
Yes, and then some. Stolo covers the full NSE F&O universe: Nifty 50, BankNifty, FinNifty, Midcap Nifty, Sensex, and 191 individual F&O stocks. Every index gets its own OI charts, PCR analysis, and option chain data across weekly and monthly expiries, and the scalping terminal and strategy builder work the same way regardless of which instrument you pick.
How much does Stolo cost?
There is a 15-day trial for a small one-time fee, and it is full access, not a stripped-down version. After that you can go monthly or annual, and the annual plan works out cheaper per month. Every plan, trial included, gets the same feature set: OI analysis, strategy builder, broker-integrated terminal, order analysis, and trading journal. No hidden fees, no per-trade charges.
Can beginners use Stolo without prior options knowledge?
Yes. There is a full Learn section with walkthroughs in English and Hindi covering the basics: what open interest actually means, how to read PCR, when a straddle makes more sense than a strangle, explained in plain terms rather than textbook theory. Most new traders spend some time in the strategy builder on paper before risking real orders, and the Telegram community is a good place to ask beginner questions.
Is there a mobile app for Stolo?
Not yet, not a dedicated one. Stolo is built as a web platform for desktop use during market hours, because active trading with OI charts and a terminal genuinely needs the screen space. It is responsive enough on mobile to check positions or glance at analysis on the go, and a proper mobile experience is on the roadmap. For the full scalping terminal and strategy builder, a desktop or laptop is recommended for now.
