Gamma exposure measures the aggregate gamma of outstanding option contracts on an underlying, usually expressed per one-percent or one-point move. It estimates how much dealer hedging flow could be triggered by price movement. High absolute gamma exposure means larger hedging flows and a market more sensitive to position-driven moves.

The gamma flip is the price level where net gamma exposure changes sign. Above the flip, dealer hedging tends to dampen movement; below it, hedging tends to amplify movement. It is a reference level for regime behavior, not a prediction of direction.

A gamma wall is a strike with unusually large open interest, where dealer hedging concentrates. As price approaches such a strike, hedging flows can slow or pin the move, which is why walls often behave like short-term support or resistance. Walls shift as open interest changes, especially around expiration.

In a positive gamma regime, dealers generally sell into rallies and buy into dips to stay hedged, which stabilizes price. In a negative gamma regime, dealers must buy rallies and sell dips, which can accelerate moves in both directions. The gamma flip level marks the boundary between the two.

IV rank compares current implied volatility to its own range over the past year, expressed as a percentile. A high IV rank means options are pricing more expected movement than usual; a low rank means less. It provides context for whether the expected move is historically large or small.

No. Gamma exposure describes positioning and how the market might behave around key levels, not where it will go. A wall can act as support until positioning changes and it no longer does. Always combine gamma context with price structure, news, and other independent inputs.
