Base Prices
Base price of the options contracts, on introduction of new contracts, would be the theoretical value of the options contract arrived at based on Black-Scholes model of calculation of options premiums.
The options price for a Call, computed as per the following Black Scholes formula:
C = S * N (d1) - X * e- rt * N (d2)
and the price for a Put is : P = X * e- rt * N (-d2) - S * N (-d1)
where :
d1 = [ln (S / X) + (r + σ2 / 2) * t] / σ * sqrt(t)
d2 = [ln (S / X) + (r - σ2 / 2) * t] / σ * sqrt(t)
= d1 - σ * sqrt(t)
C = price of a call option
P = price of a put option
S = price of the underlying asset
X = Strike price of the option
r = rate of interest
t = time to expiration
σ = volatility of the underlying
