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 example also provides a clear example of why significant amounts of capital are needed.
The currency should eventually turn, but you may not have enough money to stay in the market long enough to achieve a successful end. That is the downside to the martingale strategy. One of the reasons the martingale strategy is so popular in the currency market is that currencies, unlike stocks , rarely drop to zero.
Although companies can easily go bankrupt, most countries only do so by choice. There will be times when a currency falls in value. However, even in cases of a sharp decline , the currency's value rarely reaches zero. The FX market also offers another advantage that makes it more attractive for traders who have the capital to follow the martingale strategy. The ability to earn interest allows traders to offset a portion of their losses with interest income.
That means an astute martingale trader may want to use the strategy on currency pairs in the direction of positive carry. In other words, they would borrow using a low interest rate currency and buy a currency with a higher interest rate. A great deal of caution is needed for those who attempt to practice the martingale strategy, as attractive as it may sound to some traders. The main problem with this strategy is that seemingly surefire trades may blow up your account before you can profit or even recoup your losses.
In the end, traders must question whether they are willing to lose most of their account equity on a single trade. Given that they must do this to average much smaller profits, many feel that the martingale trading strategy offers more risk than reward. Michael Mitzenmacher, Eli Upfal.

Key Takeaways The system's mechanics involve an initial bet that is doubled each time the bet becomes a loser. All you need is one winner to get back all of your previous losses.
Unfortunately, a long enough losing streak causes you to lose everything. The martingale strategy works much better in forex trading than gambling because it lowers your average entry price. Article Sources. Investopedia requires writers to use primary sources to support their work. These include white papers, government data, original reporting, and interviews with industry experts.
But eventually you will hit one large loss that will bankrupt you. All the Martingale system really achieves is a change in the distribution of risks. Although you may turn a profit in the short run, you would need an infinite bankroll and infinite spins to make a profit in the long run. The Martingale system might seem to offer the sports bettor a chance of profiting since each win will recover his preceding losses and add a little extra each time.
The preceding analysis, however, hopefully convinces you that the Martingale system is both mathematically flawed and very risky, since any extended run of consecutive losses will soon increase the stake size to very high levels. For example, 10 even-money losses in succession, will require the 11th stake to be 1, units, just to win 1. Depending on the size of bet you start with, this might be more than the accepted limits of your bookmaker.
Even more likely, it might be larger than the size of your remaining bankroll. In theory, with an infinite bankroll , infinite number of bets and a bookmaker with infinite limits, one could argue that the Martingale system will be a winning strategy in the long run.

Except, of course, that is unrealistic and why would you even bother gambling if you had infinite bankroll to begin with? Interested in reading more about betting systems? Using Martingale in Sports Betting The Martingale system might seem to offer the sports bettor a chance of profiting since each win will recover his preceding losses and add a little extra each time.
An Illusion In theory, with an infinite bankroll , infinite number of bets and a bookmaker with infinite limits, one could argue that the Martingale system will be a winning strategy in the long run. The gambler might bet 1 unit on the first spin. On each loss, the bet is doubled. Thus, taking k as the number of preceding consecutive losses, the player will always bet 2 k units.
With a win on any given spin, the gambler will net 1 unit over the total amount wagered to that point. Once this win is achieved, the gambler restarts the system with a 1 unit bet. With losses on all of the first six spins, the gambler loses a total of 63 units. 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".
