SPX Gamma Exposure (GEX) Levels
SPX is the institutional gamma map behind the entire S&P 500 — cash-settled, deeply liquid, and the home of the 0DTE complex that dominates modern intraday flow.
This page explains what the SPX gamma map means. It shows no live numbers — the live, refreshed map lives in the indicator. Educational context only; nothing here is a signal or advice.
Why dealer positioning moves SPX
Because SPX carries the large, hedging-driven blocks that SPY only echoes, its walls and gamma flip are the reference every desk watches. In long-gamma regimes price mean-reverts between the put and call walls; when the flip gives way, hedging turns from dampening to amplifying — the difference between a coil and a trend day.
The map is built from the live options chain: the call wall (heaviest call gamma above spot), the put wall (its mirror below), the gamma flip (where the net dealer position changes sign) and the vol trigger. Together they describe how hedging flows are likely to lean on price — dampening moves in long-gamma regimes, amplifying them in short-gamma ones.
How traders read the SPX map
- Walls as reaction zones — the SPX call and put walls mark where dealer hedging concentrates; approaches are where behaviour most often changes.
- The flip as the regime line — above it, hedging dampens; below it, hedging amplifies. Same chart, two different games.
- Structure, not signals — the map says where the crowd is positioned, never what to do about it.
