CORE MODEL

Gamma changes delta
Near expiration or near the strike, delta can move quickly and invalidate static assumptions.
Theta is conditional
Time decay is not collected smoothly and can be overwhelmed by price and volatility changes.
Vega needs a horizon
Volatility sensitivity differs by expiration, strike and position structure.
