Pathwise Integration

Algorithm

Pathwise integration, within financial modeling, represents a Monte Carlo method for estimating the expected value of a function of an Itô process. This technique directly simulates sample paths of the underlying stochastic process, evaluating the function along each path and averaging the results, offering a direct approach to valuation. Its application in cryptocurrency derivatives pricing addresses the non-linearity inherent in many exotic options and complex financial instruments where closed-form solutions are unavailable, providing a robust numerical alternative. The method’s efficacy relies on the assumption that the integrand function is sufficiently smooth, ensuring convergence and minimizing path-dependent errors.
