What does gamma γ represent when trading options?

Gamma. Gamma (Γ) represents the rate of change between an option’s delta and the underlying asset’s price. This is called second-order (second-derivative) price sensitivity. Gamma indicates the amount the delta would change given a $1 move in the underlying security.

How does delta and gamma work in options?

Gamma is the rate that delta will change based on a $1 change in the stock price. So if delta is the “speed” at which option prices change, you can think of gamma as the “acceleration.” Options with the highest gamma are the most responsive to changes in the price of the underlying stock.
