Inputs in Black-Scholes Option Pricing Model Formula
- S0 = underlying price
- X = strike price
- σ = volatility
- r = continuously compounded risk-free interest rate
- q = continuously compounded dividend yield
- t = time to expiration
For,
- σ = Volatility = India VIX has been taken.
- r = 10% (As per NSE Website, it is fixed.)
- q = 0.00% (Assumed No Dividend)
Note: In many resources, you can find different symbols for some of these parameters in the Black Scholes Formula. For example,
- The strike price is often denoted
K
(Here it isX
). - The underlying price is often denoted
S
(without the zero) - Time to expiration is often denoted
T – t
(difference between expiration and now).
