## What is the 'Anti-Martingale System'

You go for the best that you believe will come in. You can also test out the Reverse Martingale on our free game below. Desktop Only, not available on mobiles. The key problem with positive progression roulette systems like the Reverse Martingale or Anti Martingale, is that, by the law of averages, you are going to lose a bet at some point.

Now, if you are doubling up your bets after a win, you are going to wipe out all of your profits in one foul swoop if you are not very disciplined and pull out. So, this betting system requires you to stick to strict money management practices.

You need to bank your profits along the way, and reset your entry bet levels. Then it all comes down to whether you hit a winning streak, and whether you can acurately predict how long that streak is. Remember, the longer you go on, the more profit you are going to wipe out after a loss, so don't get greedy. No system will improve the fundamental odds you get at the roulette table.

But playing a system like the Reverse Martingale might help you get your money out when you are in profit- so that's no bad thing. If you are going to use this system, here are a few tips: Limit yourself to short streaks of 3 or 4, stop, and then play another streak starting at your lower starter bet.

In this example, the probability of losing the entire bankroll and being unable to continue the martingale is equal to the probability of 6 consecutive losses: The probability of winning is equal to 1 minus the probability of losing 6 times: Thus, the total expected value for each application of the betting system is 0.

In a unique circumstance, this strategy can make sense. Suppose the gambler possesses exactly 63 units but desperately needs a total of Eventually he either goes bust or reaches his target. This strategy gives him a probability of The previous analysis calculates expected value , but we can ask another question: Many gamblers believe that the chances of losing 6 in a row are remote, and that with a patient adherence to the strategy they will slowly increase their bankroll.

In reality, the odds of a streak of 6 losses in a row are much higher than many people intuitively believe. Psychological studies have shown that since people know that the odds of losing 6 times in a row out of 6 plays are low, they incorrectly assume that in a longer string of plays the odds are also very low.

When people are asked to invent data representing coin tosses, they often do not add streaks of more than 5 because they believe that these streaks are very unlikely. This is also known as the reverse martingale.

In a classic martingale betting style, gamblers increase bets after each loss in hopes that an eventual win will recover all previous losses. The anti-martingale approach instead increases bets after wins, while reducing them after a loss. The perception is that the gambler will benefit from a winning streak or a "hot hand", while reducing losses while "cold" or otherwise having a losing streak.

As the single bets are independent from each other and from the gambler's expectations , the concept of winning "streaks" is merely an example of gambler's fallacy , and the anti-martingale strategy fails to make any money. If on the other hand, real-life stock returns are serially correlated for instance due to economic cycles and delayed reaction to news of larger market participants , "streaks" of wins or losses do happen more often and are longer than those under a purely random process, the anti-martingale strategy could theoretically apply and can be used in trading systems as trend-following or "doubling up".
