What is the formula for a martingale?

This sequence is thus a martingale. Let Y_n = X_n² − n where X_n is the gambler's fortune from the preceding example. Then the sequence { Y_n : n = 1, 2, 3, ... } is a martingale. This can be used to show that the gambler's total gain or loss varies roughly between plus or minus the square root of the number of steps.

The useful property of martingales is that we can verify the martingale property locally, by proving either that E[X_t+1|ℱ_t] = X_t or equivalently that E[X_t+1 - X_t|ℱ_t] = E[X_t+1|ℱ_t] - X_t = 0.
