Calculates the price of a lookback option using a Monte Carlo (MC) Simulation. Carries the assumption that the asset price is observed continuously. Assumes that the the option o followes ds = mu * S * dt + sqrt(vol) * S * dz where dz is a Wiener Process. Assume that without dividends, mu are default to be r.

o |
The |
NPaths |
How many time of the simulation are applied. Coustomer defined. |
div |
number to decide length of each interval |
Type |
Specifies the Lookback option as either Floating or Fixed- default argument is Floating. |
To price the lookback option, we require the S0, K, and ttm arguments from object Opt
and r, q, vol from object OptPx defined in the package. The results of simulation would
unstable without setting seeds.
A list of class LookbackMC
consisting of the input object OptPx
and the price of the lookback option based on Monte Carlo Simulation (see references).
