Amel Bentata : The finite horizon case.

Roughly, the Black-Scholes formula is a distribution function of the maturity. This may be explained in terms of the last passage times at a given level of the underlying Brownian motion with drift.

Conversely, starting with last passage times up to finite horizon, we obtain a 2-parameter variant of the Black-Scholes formula.
