    Why does Gamma increase near expiry?

    Gamma increases near expiry because option premiums become highly sensitive to small market movements. As expiry approaches, Delta changes faster, causing option prices to move more sharply.

    If the market moves in the trader’s favour, Gamma increases Delta and can accelerate profits. If the market moves against the trader, Gamma reduces Delta and may increase losses.

    Gamma and Moneyness:

    - ATM Options: Highest Gamma, highly responsive and volatile

    - ITM Options: Lower Gamma, more stable

    - OTM Options: Lower Gamma, less responsive to market movement
