Call walls, put walls, and the gamma flip — drawn on the same chart as the DOM ladder, the footprint, and the tape. Recomputed intraday as 0DTE flow rebuilds the surface, not frozen in an 8am PDF. One tab, not a separate dashboard. A native desktop terminal for Windows.
In a market where 0DTE is the majority of SPX option volume, the gamma surface rebuilds through the session. A morning GEX report is a museum exhibit by 11am — and it was never on the chart you trade.
Most GEX tools are read-only dashboards. You read a level in one window, then alt-tab to your DOM and chart in another and eyeball where it lands. The level never sits on the order flow you're reading.
Dedicated dealer-positioning services charge around $250/mo for real-time GEX by itself — no DOM, no footprint, no tape. You still pay for the rest of the stack separately.
Call wall, put wall, gamma flip, max pain, expected move, high-gamma zones, vanna, charm, and the 0DTE percentage — drawn directly on the price chart, next to the DOM ladder and the footprint.
Black-Scholes gamma on live implied volatility, resummed through the session as the surface rebuilds — so the walls you trade are the walls that are there now, not the ones from the open.
The whole point: dealer levels sit on the DOM, footprint, and tape you're already reading. When price approaches a call wall, you see the absorption on the ladder at the same moment.
