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. Free while in beta, no card.

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.
