In the Black-Scholes normal formula above, if you investigate the term $(F-K)N(d_1)$ in a spreadsheet, you’ll see that for small levels of volatility and maturity (try, for example, $\sigma=0.0025$, Maturity=1) it is actually quite close to $\max(0,F-K)$ – which is the intrinsic value of the call. The Black-Scholes formula helps investors and lenders to determine the best possible option for pricing. The Black Scholes Calculator uses the following formulas: C = SP e-dt N (d 1) - ST e-rt N (d 2) P = ST e-rt N (-d 2) - SP e-dt N (-d 1) d1 = ( ln (SP/ST) + (r - d + (σ2/2)) t ) / σ √t. 2018-08-01 Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … def generalized_black_scholes (s, k, r, b, sigma, t, option = 'call', exact = False): if option not in ('call', 'put'): raise ValueError ('option parameter must be one of "call" (default) or "put".') if exact: d1 = (sympy. ln (s / k) + t * (b + sigma ** 2 / 2)) / (sigma * sympy. sqrt (t)) d2 = d1-sigma * sympy. sqrt (t) n = Normal ("x", 0.0, 1.0) if option == 'call': price = s * sympy.
