In some cases, your pockets must be infinitely deep. A martingale strategy relies on the theory of mean reversion. Without a plentiful supply of money to obtain positive results, you need to endure missed trades that can bankrupt an entire account.
It's also important to note that the amount risked on the trade is far higher than the potential gain. Despite these drawbacks, there are ways to improve the martingale strategy that can boost your chances of succeeding.
The martingale was introduced by the French mathematician Paul Pierre Levy and became popular in the 18th century.
The system's mechanics involve an initial bet that is doubled each time the bet becomes a loser. Given enough time, one winning trade will make up all of the previous losses.
The 0 and 00 on the roulette wheel were introduced to break the martingale's mechanics by giving the game more possible outcomes.
That made the long-run expected profit from using a martingale strategy in roulette negative, and thus discouraged players from using it. To understand the basics behind the martingale strategy, let's look at an example.
There is an equal probability that the coin will land on heads or tails. Each flip is an independent random variable , which means that the previous flip does not impact the next flip.
The strategy is based on the premise that only one trade is needed to turn your account around. Unfortunately, it lands on tails again.
As you can see, all you needed was one winner to get back all of your previous losses. However, let's consider what happens when you hit a losing streak:.
You do not have enough money to double down, and the best you can do is bet it all. You then go down to zero when you lose, so no combination of strategy and good luck can save you.
You may think that the long string of losses, such as in the above example, would represent unusually bad luck. But when you trade currencies , they tend to trend, and trends can last a long time.
The trend is your friend until it ends. The key with a martingale strategy, when applied to the trade, is that by "doubling down" you lower your average entry price.
As the price moves lower and you add four lots, you only need it to rally to 1. The more lots you add, the lower your average entry price.
On the other hand, you only need the currency pair to rally to 1. This exhausts the bankroll and the martingale cannot be continued. 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: what is the chance that one can play a casino game using the martingale strategy, and avoid the losing streak long enough to double one's bankroll.
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".
