On the dependence between a Wiener process and its running maxima and running minima processes

Abstract

We study a triple of stochastic processes: a Wiener process WtW_t, t0t \geq 0, its running maxima process Mt=sup{Ws:s[0,t]}M_t=\sup \{W_s: s \in [0,t]\} and its running minima process mt=inf{Ws:s[0,t]}m_t=\inf \{W_s: s \in [0,t]\}. We derive the analytical formulas for the joint distribution function and the corresponding copula. As an application we draw out an analytical formula for pricing double barrier options.
