What is Gamma Exposure (GEX)?

Gamma Exposure represents the sensitivity of an option's delta to changes in the underlying price. Market makers hedge their gamma exposure, creating support/resistance at high GEX strikes.

Key Levels:

  • Call Wall: Strike with highest positive GEX (resistance)
  • Put Wall: Strike with the largest put GEX, shown as the deepest negative bar (support)
  • Gamma Flip: Where total GEX changes from negative to positive

Positive GEX: Market makers sell into rallies, buy into dips (stabilizing).

Negative GEX: Market makers buy into rallies, sell into dips (amplifying moves).
