Interactive levels → How to read it → updated ~30min, market hours

Where SPX is trading right now relative to today's five strongest 0DTE gamma concentrations. The other GEX charts on this page put gamma on the strike axis, which shows where the gamma sits but not where price sits inside it. Gold marks positive gamma, where dealer hedging dampens moves into the level. Purple marks negative gamma, where it amplifies them. Line thickness scales with strength relative to the day's largest magnet, which carries the star. The dashed FLIP line is the strike where per-strike net gamma changes sign, a different level from the Volatility Trigger and Zero Gamma on the profile charts below. Bigger dots in the VEX column mean more vanna exposure at that strike. Levels are weighted by open interest, so they mostly move overnight rather than through the session.

The interactive levels page carries the same snapshot with a tab per expiration and the full ranked strike table. It refreshes itself every five minutes and keeps its own dark theme.
