Unique feature: overlay SPX options Gamma Exposure data directly onto ES (S&P 500 futures) charts. Trade futures with options flow intelligence — see Call Walls, Put Walls, and Gamma Flip levels overlaid on your ES candlestick chart in real time. The GEX-to-futures price anchor is calibrated daily at 4:00 PM ET for precision.
Screen for abnormal small-cap events, track earnings calendars, analyze option chains, and monitor sector rotation with interactive heatmaps.
SPX options are the most liquid index options market in the world. They're where the gamma is. But ES futures (E-mini S&P 500) are what professional traders actually trade — tighter spreads, nearly 24-hour liquidity, and better leverage. The problem has always been: GEX data lives in SPX options, but price action lives in ES futures.
Our SPX GEX to ES overlay bridges this gap. We compute all gamma levels (Call Wall, Put Wall, Gamma Flip, Max Pain, Zero Gamma) from SPX options data, then project them onto ES futures price coordinates using a daily anchor calibrated to the 4:00 PM ET close. The result: you see exactly where dealer gamma walls sit on the same chart you're trading.
Real-time ES futures price action with volume-weighted K-lines (vw500, vw1000, vw2000, vw3000) plus standard 1m/5m intervals.
Call Wall, Put Wall, Gamma Flip, Max Pain, and HVL plotted as horizontal lines on the ES chart. Updated every minute from live SPX options data.
SPX-to-ES price mapping anchored at each trading day's 4:00 PM ET close. Ensures GEX levels maintain accurate relative positioning throughout the session.
No need to trade SPX options to use GEX data. Execute on ES futures with gamma-informed entries and exits. Use the Gamma Flip as your intraday bias filter.
This feature is designed for ES day traders who want options flow intelligence without switching between platforms. Instead of monitoring GEX on one screen and trading ES on another, you see gamma walls, flip levels, and dealer positioning directly on your ES futures chart — one chart, all the data.

Gamma Exposure (GEX) is the total dollar value of gamma risk held by options market makers across all strikes. When GEX is positive, dealer hedging stabilizes prices (buy dips, sell rips). When GEX is negative, dealer hedging amplifies trends (sell into weakness, buy into strength). GEX is measured in dollars per 1% move of the underlying.
The Call Wall is the strike price with the largest call gamma — it acts as a resistance level where dealers sell into strength. The Put Wall is the strike with the largest put gamma — it acts as a support level where dealers buy dips. These walls are the market's built-in range boundaries derived from options positioning.
The Gamma Flip is the price level where net gamma crosses from positive to negative. Above the Gamma Flip, dealers are long gamma (market stabilizing). Below the Gamma Flip, dealers are short gamma (market amplifying). It is the single most important intraday level for determining directional bias, especially on 0DTE expiration days.
Vanna measures how an option's Delta changes when implied volatility moves — it captures the spot-volatility correlation effect. Charm measures how Delta changes as time passes — it captures time-decay-driven hedging flows. Both are second-order Greeks critical for understanding intraday dealer flow dynamics beyond first-order Gamma.
Max Pain is the strike price at which the total value of all outstanding options (calls + puts) would expire worthless. Market makers, who are net option sellers, profit most when price settles at Max Pain at expiration. Price tends to gravitate toward Max Pain as expiration approaches, making it a reliable mean-reversion reference level.
