Understanding Options Pricing

Options pricing is based on several key factors including the underlying asset price, strike price, time to expiration, volatility, and risk-free interest rate. Our calculators use the Black-Scholes model, the industry standard for European options pricing.

The Greeks Explained:

Delta (Δ): Price sensitivity to underlying asset price changes

Gamma (Γ): Rate of change of delta

Theta (Θ): Time decay - how option value decreases over time

Vega (ν): Sensitivity to volatility changes

Rho (ρ): Sensitivity to interest rate changes

Understanding these metrics is crucial for effective options trading and risk management. Each calculator provides detailed explanations to help you make informed trading decisions.
