This app calculates the option price and Greeks up to the 3rd order according to the Black-Scholes model. Under the hood it is using my [blackscholes](https://github.com/CarloLepelaars/blackscholes) open source Python library. To learn more about the implementation and formulas, check out the [full documentation](https://carlolepelaars.github.io/blackscholes/3.the_greeks_blackscholes/). If you are serious about studying option theory check out [Paul Wilmott on Quantitative Finance](https://amzn.to/49hU8KY) and [Nassim Taleb's Dynamic Hedging](https://amzn.to/4fNdDgL).

The theoretical value of the option according to the Black-Scholes model.
Price
7.2055
Rate of change in option price with respect to the forward price (1st derivative).
Delta
0.8025
Rate of change in delta with respect to the underlying asset price (2nd derivative). Measures the convexity of the option value.
Gamma
0.0313
Rate of change in option price with respect to volatility. Measures sensitivity to volatility changes.
Vega
14.4975
Rate of change in option price with respect to time (time decay). The value is annualized - divide by 365 for daily decay.
Theta
-2.0296
Rate of change in option price with respect to the dividend yield. Also known as psi.
Epsilon
-44.1366
Rate of change in option price with respect to the risk-free interest rate.
Rho
36.9311
Sensitivity of delta with respect to change in volatility (cross derivative). Shows how delta changes with volatility.
Vanna
-1.3362
Rate of change of delta over time (delta decay). Also known as the second order time decay.
Charm
0.0626
Second order sensitivity to volatility. Shows how vega changes with changes in volatility.
Vomma
66.9081
Rate of change in vega with respect to time. Shows how volatility sensitivity changes with time.
Veta
9.1523
Second order partial derivative with respect to strike price. Used in Breeden-Litzenberger formula for estimating risk-neutral probabilities.
Phi
0.0379
Rate of change in gamma with respect to the underlying price. Third derivative showing how gamma changes with price.
Speed
-0.0040
Rate of change of gamma with respect to volatility. Shows how gamma changes with volatility.
Zomma
-0.0642
Rate of change of gamma over time. Shows how gamma changes as time passes.
Color
-0.0111
Third derivative of option value with respect to volatility. Shows sensitivity of vomma to volatility changes.
Ultima
-1043.8701
First derivative of option price with respect to strike price. Shows sensitivity to strike price changes.
