Methodology
This template implements the Garman-Kohlhagen model (1983), which extends Black-Scholes to currency options by incorporating both domestic and foreign interest rates. The model treats holding foreign currency as equivalent to owning a dividend-paying asset, where the "dividend yield" equals the foreign risk-free rate. All formulas are visible and editable for educational analysis.

- European-style options (exercise at expiration only)
- Constant interest rates and volatility over the option's life
- No transaction costs or bid-ask spreads
