Option Gamma is a hedge parameter, one of the so-called Greeks. It measures the rate of change in Delta in response to changes in the underlying price. In mathematical sense, Gamma is the second derivative of option price with respect to underlying price.
Gamma is positive for long option positions; for short positions, it is negative. Gamma is typically greatest for at-the-money options.
