GEX Heatmap
Gamma exposure broken out across both strike and expiration at once, instead of collapsed into a single profile.
What is a GEX heatmap?
A GEX heatmap is a strike by expiration grid of gamma exposure for one ticker. Rows are strikes. Columns are expiry dates. Green is Positive GEX (pinning). Red is Negative GEX (volatility). GEX Details is the other tab. That table is one row per expiration, not one cell per strike. It is a map, not a trade.
Gamma Exposure is a strike table that collapses expirations into one row of walls. Greeks Heatmap is a strike by expiry map with GEX, VEX, CEX, DEX, OI, and Gravity Magnet Score. Net Premium Heatmap is a strike by expiry grid of Net Premium dollars. This page is GEX only on the grid. Search ticker and Go load the name. Strikes starts at 10. Expirations starts at 16. The highlighted strike is nearest last price. A loud green cell can still be a hedge, a spread, or a dealer book. A loud red cell is not an order to fade the next print. GEX Details by Expiration is the second tab. Each row is one listed date. Columns are Expiration Date, DTE, GEX, DEX, GEX Normalized, DEX Normalized, OI Normalized, GEX Change 1D, DEX Change 1D, Call Resistance, Put Support, High Vol. Level, and Expiry Exp. Move. Far dates can print N/A on the one-day change columns. None of those rows is a forecast.
On EZPZ, the live page title is GEX Heatmap. The ticker line starts on SPY plus last price. Tabs are GEX Heatmap and GEX Details. The heatmap legend is Positive GEX (pinning) and Negative GEX (volatility). GEX Details uses Filter ticker and Go, and Expirations starts at 16. There is no Strikes control on that table. Gamma Exposure is the searchable strike table with Call Wall and Put Wall for one ticker, not this expiry grid. Greeks Heatmap is the strike-by-expiration grid with Gravity Magnet Score. Net Premium Heatmap is the strike-by-expiration grid of Net Premium for one ticker. Market Maker Exposure is the SPX Flip Level chart with Call Wall, Put Wall, and Expected Move(VEM) and DEM.

Weekly-DTE Graph is the WTE chart of premium that expires by Friday. 7-DTE Graph is the 7DTE chart of premium in the next 7 days. Supply and Demand X-ray is the ITM Call and Put chart of Price, Supply, and Demand. Money Sentiment is Bought Ratio, Net Sentiment, and Netflow Graph for one ticker. Movers and Shakers Tide is that same chart job for about 18 mega-cap names. Option Chain is the listed book for one ticker. Live Flow is the tape of prints. Unusual Activity keeps only large, sweep, and block prints.

Put to Call Ratio is the Intraday Put/Call Ratio chart of Traded PCR, OI PCR, and Sentiment PCR. Max Pain is Intraday Max Pain with O-Max Pain, P-Max Pain, and V-Max Pain. Open Interest Scan is the OI per Strike and OI per Expiration chart pair. Volume Scan is the Volume by Strike and Volume by Expiration chart pair.

Volatility Surface 3D is Raw Contracts and Smoothed Mesh for one ticker.
How GEX Heatmap works on EZPZ
Search a ticker, leave GEX Heatmap on, then read the highlighted strike first. It is not a score. Scan that strike across expiries, then scan the same expiry up and down. Open GEX Details when you want one row per date with Call Resistance, Put Support, and GEX Change 1D. The heatmap shot in this guide used Expirations 20. The page still starts at 16.
How this differs from Greeks Heatmap
Greeks Heatmap is a strike by expiry map with six panels. GEX, VEX, CEX, and Gravity start on. This page is GEX only on the grid, then GEX Details by Expiration. Use Greeks Heatmap when you want VEX, CEX, DEX, OI, or Gravity Magnet Score. Use this page when you want pinning versus volatility cells, then Call Resistance and Put Support by date. Use Gamma Exposure when you want Call Wall and Put Wall on a collapsed chain. Use Net Premium Heatmap when you want Net Premium dollars, not GEX. Use Market Cross Flow when you want SPY, SPXW, and QQQ side by side next to candles. Use Market Maker Exposure when you want SPX Flip Level, Call Wall, Put Wall, and Expected Move(VEM) and DEM. Use Option Depth Flow when you want strike by time. Use Ticker Explorer when you want GEX and DEX charts next to quote and unusual activity. Use Largest Premium By Tickers when you still need a name from Bullish Flow or Bearish Flow. Use Index Trader when you want traffic lights. Use Top 20 Optionable when you want Vol. * Price rank. Use Market Wave when you want Current Day Net Call Premium versus Net Put Premium. Use Net Flow Graph when you want Filter ticker plus Cumulative Volume Delta. Use Historical Net Premium when you want the 15D table. Use 0DTE Graph when you want same-day premium. Use Weekly-DTE Graph when you want Friday. Use 7-DTE Graph when you want the next 7 days. Use Supply and Demand X-ray when you want Price, Supply, and Demand on each contract. Use Money Sentiment when you want Bought Ratio and Net Sentiment. Use Movers and Shakers Tide when you want the 18-name basket. Use Live Flow when you want the prints. Use Option Chain when you want the listed book.

How people actually use it
Read last price, then the highlighted strike
Check the ticker line. Find the highlighted strike. Compare that strike across expiries before you hunt far from spot.
Leave GEX Heatmap on first
Most sessions start on the grid. Open GEX Details when you want Call Resistance, Put Support, and GEX Change 1D by date.
Treat pinning and volatility as labels
The legend is Positive GEX (pinning) and Negative GEX (volatility). Those are colors on the grid. They are not a forecast.
Use it next to the walls and the tape
This page is GEX by strike and expiry. Open Gamma Exposure if you want Call Wall and Put Wall. Open Live Flow if a cell makes you want the prints.
