This program is to calculate price and greak letter for regular option by Black Scholes method. Since using Black Scholes, price and greak letter can be compute efficiently within O(1). There are also different pricing models and I will work on them in the near future.
The formula for Black Scholes pricing and and greak letters is shown below. If you wish to dig into more, there are abundant of resource on the internet and I am planing on writing a medium on it.
-
Call Price: The theoretic price for call option
-
Put Price: The theoretic price for put option
-
Delta: Measure the rate change of option price w.r.t underlying stock price
-
Gamma: Measure the rate change of Delta w.r.t underlying stock price
-
Vega: Measure the sensitive of price to volatility
-
Rho: Measure the sensitive of price to interest rate
-
Theta: Time decay, namely, measure the sensitive of price to maturity time
