How Does Gamma Behave for a DITM Option?

Gamma measures the rate of change of Delta. For a deep in-the-money (DITM) option, Gamma is very low, approaching zero.

This is because the Delta is already near its maximum (1.0 for a call) and is less sensitive to further price changes in the underlying asset.
