What Are GEX Levels?

Gamma Exposure (GEX) levels reveal where market makers are forced to hedge their options positions. These hedging flows create invisible support, resistance, and magnet zones that traditional technical analysis misses.

King Node: the strike with the highest gamma concentration. Price is magnetically attracted to this level and tends to consolidate around it.

Gamma Wall: the highest call-side gamma strike above spot. Acts as a ceiling where dealer hedging absorbs buying pressure.

Put Wall: the highest put-side gamma strike below spot. Acts as a floor where dealer hedging absorbs selling pressure.

These levels update every minute during market hours (9:30 AM to 4:00 PM ET) based on live options flow data.
