We read open interest against price on every F&O name, all session, and tell you in a sentence where positions are being built while the chart still looks quiet.
MOST TOOLS SHOW YOU CHARTS. WE SHOW YOU WHAT'S BUILDING BEFORE THE CHART MOVES.

For every F&O stock, GreekNova solves implied volatility from live option prices, works out each strike's gamma, and weights it by open interest. The result: the strikes that tend to act as walls, and whether dealer hedging is likely to amplify a move or hold price in place.
Illustration of how the view is laid out. Not real data, not a live signal.
The strikes carrying the most gamma-weighted open interest on each side. Real hedging concentration, not just raw OI, and they tend to act as resistance and support.
Short gamma: dealer hedging tends to amplify moves. Long gamma: it tends to dampen them and pin price. Read live from the gamma balance around spot.
A short-gamma stock pressing into a wall is flagged. On The Verge means the wall is still ahead; Active Squeeze means price has already pushed through it.
Tags premium as rich or cheap against the stock's own realised volatility, so an event-inflated setup does not look like a clean one. Notional GEX ranks magnitude across stocks.
Gamma and wall levels are model estimates from option prices and open interest, shown for educational and informational use. They are not predictions, buy/sell recommendations or investment advice. GreekNova is not SEBI registered.
Four systems, each solving a different blind spot the raw options chain leaves you to work out yourself.
| Feature | What it does | |
|---|---|---|
| Positional Intelligence | Classifies OI-vs-price buildup: long buildup, short buildup, covering, unwinding, with a tiered conviction score (Radar → Building → Conviction → Ignition), across the full F&O universe. | Flagship |
| UOA / Options Jungle | Strike-level unusual options activity that separates genuine buying from writing using OI and price together, not just a volume spike. | Strike-level |
| Weekly OI Buildup | A multi-day view of positioning, so you catch accumulation building across the week, not just what one session shows. | Multi-day |
| Delivery Confluence | Cross-checks futures open interest against actual cash-market delivery data, a layer most retail F&O tools skip entirely. | Rare |
TATA ELXSI, 14 October 2026. This is what the Spot Volume Breakout Scanner is built to catch: a towering volume day standing far above everything around it.
Real GreekNova data (Tata Elxsi close-price and NSE volume, 1 Sep – 16 Oct 2026), shown as a historical illustration of how the scanner flags a breakout. Not a live signal, prediction, or recommendation to trade this or any stock.
| Signal | What it does | |
|---|---|---|
| Buildup direction | Long buildup, short buildup, covering or unwinding: every F&O name classified in real time from how open interest and price move together, not price alone. | 01 |
| Stealth buildup | Large open interest going on while the candle barely moves. The setups that don't show up on a price chart yet, by design, before the move. | 02 |
| PCR crossover | Put-Call Ratio read against volume PCR, session over session, translated into plain language instead of a number you have to interpret yourself. | 03 |
| Relative strength | Every stock benchmarked against its index, so you can tell a genuine breakout from a name just riding the broader tape. | 04 |
Strike-wise OI, IV, PCR: all there, all raw. You still have to scan every name yourself and decide what it means.
The same underlying data, scanned across the full F&O universe automatically, and handed to you as a plain-language read, not a table to interpret at 9:20am.
Built specifically to catch quiet buildup: OI moving while price hasn't, the setups a price chart alone won't show you yet.
Beyond the four flagship systems above: everything else that ships with a subscription.
A short read at market close: what actually moved, what we flagged, and what's carrying into tomorrow.
Which names saw genuine buildup versus unwinding today, summarized the way we'd say it to you directly.
A running scoreboard: of what we flagged this session, how price actually moved into the close.
A short watchlist of names with overnight positioning worth tracking at the next open.

No. GreekNova uses a standard Zerodha Kite login purely as a read-only data stream for live NSE prices. It does not place trades, access your funds, or require Kite Connect's paid developer API plan.
Both, in different ways. The live feeds (Gamma Exposure, Session Replay, intraday alerts) update through the day for shorter-horizon decisions, while Positional Intelligence and the EOD/Morning reports are built for multi-day buildup and swing positioning.
Yes. You can open a free/secondary Zerodha account used purely as the live data pipe for GreekNova, while continuing to trade through whichever broker you already use.
Scanner flags appear in your in-app alerts feed the moment they fire, alongside the daily Morning and EOD reports.
That screen comes from Zerodha, not GreekNova, and it's the same fixed screen shown for every Kite Connect app — Sensibull, Streak, Smallcase and the rest all show identical wording, because Zerodha's login token isn't scoped per-app. GreekNova itself only ever reads live market data through this connection; it never checks your balance, margins or holdings, and never places a trade. Don't take our word for it — log into any other Kite Connect app and you'll see the exact same screen.
No. You type your password only on Zerodha's own login page. GreekNova never sees it, never stores it, and has no way to access it.
