Option Gamma
Option gamma is a Greek risk metric that measures the rate of change in an option's delta for every one-unit change in the price of the underlying asset. It essentially represents the convexity of the option's value.
A high gamma indicates that the delta will change rapidly as the asset price moves, which is particularly dangerous for traders who are not adequately hedged. In the crypto market, where price movements are often parabolic, managing gamma is crucial for preventing sudden, massive losses.
When a trader is short gamma, they must buy assets as the price rises and sell as it falls, which can exacerbate market volatility. Understanding gamma is essential for any trader dealing with path-dependent options, as the proximity to a barrier often leads to extreme gamma values.
