The options positioning dashboard that keeps what it collects — dealer gamma exposure, max pain, open interest and IV surface for your whole watchlist, not just SPY, and the history to see what changed.
US-listed options. European and Asian listings have no options data here — but most large non-US companies also trade in the US as ADRs, which do: ASML, SAP, SHEL, NVO, BUD.
Nothing to install. Sign in with Google or GitHub, add your tickers, and the collector keeps running whether or not you have the tab open.
Live now, no account: SPY · QQQ · IWM · NVDA · AAPL · TSLA · GLD
The same dashboard, open source, on your own machine. Docker, five minutes, no account needed — and the code behind every number.
See where dealers are structurally forced to buy or sell as price moves. Strike × expiry heatmap, call/put walls, gamma flip level, net GEX regime.
Put/call ratio, max pain, and open-interest delta — the full positioning picture across your watchlist, not one chart per ticker.
A smoothed 3D IV surface built from your own snapshot history — no black-box vendor feed, just the chain you actually collected.
Range filters on price, strike, DTE, open interest and every Greek — screen your entire chain, not one contract at a time.
Every number on the hosted version is computed by code you can read. Self-host it, fork it, or just check the arithmetic — the shared core is byte-identical in both.
