Double the trade size after each successful wining trade, until the system has a losing trade. After the first loss, the trade size is reset to the default trade size. This strategy allows exponential growth in equity until experiencing a losing trade.

In using this system, you should be prepared to accept a substantial drawdown because the largest trade you make in a series will be a loser.

Consider your ratio of average wins to average losses, obviously an anti-martingale strategy is unsuitable for use with a system that generates large losing trades compared to winners. For example this would not be an appropriate strategy to use with short option trades because that type of trading tends to generate plenty of small winners and the occasional big loss. For someone who is quite good at cutting losses in time however, the Anti-Martingale strategy is very useful because of the rapid growth in profits that it allows.
