An example case is considered to price an option at a maturity of T years - prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity. Finally option prices are compared to Black Scholes values to verify results-An example case is considered to price an option at a maturity of T years- prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity.
