Option Gamma Exposure

Option gamma exposure, often referred to as GEX, is a measure of the aggregate gamma of all open options contracts in the market. Gamma represents the rate of change of an option's delta with respect to the underlying price.

When market makers are net long or short gamma, it forces them to trade the underlying asset in specific ways to maintain their delta-neutral positions. If the market is net long gamma, market makers tend to trade against the trend, which dampens volatility.

If the market is net short gamma, they tend to trade with the trend, which amplifies volatility. Understanding the aggregate gamma exposure of the market is essential for forecasting price behavior, especially during periods of high options activity.

It is a powerful tool for predicting market moves and identifying potential areas of support and resistance. In the crypto market, this can provide deep insights into how options flows impact spot price action.
