To understand the basics behind the martingale strategy, let's look at a simple example. Suppose we had a coin and engaged in a betting game of either heads or tails with a starting wager of $1. There is an equal probability that the coin will land on heads or tails, and each flip is independent, meaning that the previous flip does not impact the outcome of the next flip. As long as you stick with the same directional view each time, you would eventually, given an infinite amount of money, see the coin land on heads and regain all of your losses, plus $1. The strategy is based on the premise that only one trade is needed to turn your account around.
