Tip — DTE slider: Drag Days to Expiry down toward 1. Watch Gamma spike ATM (binary at expiry), Theta accelerate (decay accelerates), and Vega collapse (IV sensitivity drops near expiry).

Tip — Call vs Put: Delta is the main difference. Call Delta is always positive; Put Delta always negative. Gamma and Vega are identical for both — they share the same price sensitivity to movement and volatility.
