Columns, Rows, and Colors
Each column is an expiration date. Each row is an SPX strike. Green cells show positive GEX, red cells show negative GEX, and dark cells show neutral or weak exposure. The strike row closest to SPX spot is highlighted so the active area is easier to scan.
Why the Strike Range Matters
The public map focuses on strikes around the current SPX spot, typically within a broad nearby band. This keeps the dashboard readable and emphasizes the area most relevant to intraday traders.
How to Use Key Levels
Large positive GEX above spot may act as a resistance or pinning area. Large negative GEX below spot may identify risk zones or support areas. These labels should be treated as market structure context rather than trading instructions.
Reading Multiple Expirations
Short-dated expirations can dominate intraday behavior, while weekly expirations may provide larger structural levels. Looking across five expirations helps compare same-day pressure with nearby weekly levels.
