Martingale's simple random walk is an algorithm pertaining to the wager system, in which one assumes the course of doubling one's wager in reaction to a win or halves one's wager in reaction to a loss.
So the formula:
( Xn+1 | X0 , ... , Xn )
In this it is supposed that the random variates have a finite constraint (or this equation does not hold up to infinite purposes).

Why are the martingale models less restrictive than the random walk model?
The error term in a random walk is assumed to be iid (often white-noise), but the error in a martingale doesn't have to be. If the error is AR(1) however, then the process can't be martingale, as the error in last period is known, and so the current period error is not mean zero anymore. But the error may have second order serial correlation (like an ARCH process), and still be a martingale. The error in a random walk however must be independent of the prior error (at all orders).
