Gamma Wall Analysis
Gamma wall analysis is a quantitative finance technique used to identify price levels where large concentrations of option open interest exist, particularly at strike prices where market makers have significant gamma exposure. When a market maker sells options to traders, they must hedge their directional risk by buying or selling the underlying asset.
As the price approaches a gamma wall, the market maker must adjust their hedge aggressively to remain delta neutral. This creates a feedback loop where the hedging activity itself acts as a support or resistance level, pinning the price or causing rapid reversals.
By analyzing the aggregate gamma across all strikes, traders can predict where liquidity will be constrained or where volatility will spike. It is a critical tool for understanding order flow dynamics in crypto options markets.
