Gamma Exposure GEX

Gamma exposure, or GEX, is a metric that quantifies the total gamma risk of market makers in the options market. It represents how much market makers must buy or sell the underlying asset as its price changes to stay delta-neutral.

When GEX is positive, market makers tend to sell into strength and buy into weakness, acting as a stabilizing force. When GEX is negative, they must sell into weakness and buy into strength, which can exacerbate market volatility and create feedback loops.

In crypto, where market maker positioning is often concentrated, GEX can be a powerful predictor of market direction and volatility levels. It is a sophisticated quantitative tool used to gauge the potential for forced buying or selling by institutional liquidity providers.
