Separate conditional volatility from observed returns.
Understand discounting in a stochastic-rate model.
Translate yield movements into first-order price risk.
Study a correlated stochastic-variance model.
Interpret prices across strikes and expiries.
Build a consistent discount curve.
Start in discrete time, move to Brownian motion, then read the original pricing argument and simulate it.
