Black scholes parameters
WebBlack-Scholes Equations 1 The Black-Scholes Model Up to now, we only consider hedgings that are done upfront. For example, if we write a naked call (see Example 5.2), we are exposed to unlimited risk if the stock price rises steeply. We can hedge it by buying a share of the underlying asset. This is done at the initial time when the call is sold. WebOct 14, 2024 · Hence, the first step is to define a function with these parameters. Additionally, we add a parameter option_type to distinguish which type (call or put) we want to calculate. def black_scholes_calc(S0, K, r, T, sigma, option_type): '''This function calculates the value of the European option based on Black-Scholes formula'''
