How to Use the SPX GEX HeatMap Dashboard
The SPX GEX HeatMap dashboard helps traders monitor key gamma exposure levels across upcoming SPX option expirations.
You can use it to identify important support and resistance zones, observe where market makers may have stronger hedging activity, and track potential price attraction or rejection levels during the trading day.
Main things to watch:
Positive GEX zones
These areas may act as stabilizing levels. Price may slow down, consolidate, or find support/resistance near strong positive gamma levels.
Negative GEX zones
These areas may increase volatility. When price moves into strong negative gamma zones, market moves can become faster and more directional.
Call Wall
A large Call GEX level above the current price may act as resistance.
Put Wall
A large Put GEX level below the current price may act as support.
Gamma Flip Zone
This is the area where market structure may shift between stable and more volatile behavior.
Upcoming expirations
Compare the next several expiration dates to understand whether the key gamma levels are short-term or repeated across multiple expirations.
Trading use case:
Traders can use the dashboard to monitor where SPX may find support, face resistance, or experience stronger volatility. It is especially useful for intraday SPX, SPY, QQQ, and 0DTE options traders.
Risk note:
GEX levels are not buy or sell signals by themselves. They should be used together with price action, volume, market news, and proper risk management.
