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 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.

None of the gamblers possessed infinite wealth, and the exponential growth of the bets would eventually bankrupt "unlucky" gamblers who chose to use the martingale.

The gambler usually wins a small net reward, thus appearing to have a sound strategy. However, the gambler's expected value does indeed remain zero or less than zero because the small probability that the gambler will suffer a catastrophic loss exactly balances with the expected gain.

In a casino, the expected value is negative , due to the house's edge. The likelihood of catastrophic loss may not even be very small.

The bet size rises exponentially. This, combined with the fact that strings of consecutive losses actually occur more often than common intuition suggests, can bankrupt a gambler quickly.

The fundamental reason why all martingale-type betting systems fail is that no amount of information about the results of past bets can be used to predict the results of a future bet with accuracy better than chance.

In mathematical terminology, this corresponds to the assumption that the win-loss outcomes of each bet are independent and identically distributed random variables , an assumption which is valid in many realistic situations.

It follows from this assumption that the expected value of a series of bets is equal to the sum, over all bets that could potentially occur in the series, of the expected value of a potential bet times the probability that the player will make that bet.

In most casino games, the expected value of any individual bet is negative, so the sum of many negative numbers will also always be negative.

The martingale strategy fails even with unbounded stopping time, as long as there is a limit on earnings or on the bets which is also true in practice.

The impossibility of winning over the long run, given a limit of the size of bets or a limit in the size of one's bankroll or line of credit, is proven by the optional stopping theorem.

Let one round be defined as a sequence of consecutive losses followed by either a win, or bankruptcy of the gambler.

After a win, the gambler "resets" and is considered to have started a new round. A continuous sequence of martingale bets can thus be partitioned into a sequence of independent rounds.

Following is an analysis of the expected value of one round. Let q be the probability of losing e. Let B be the amount of the initial bet.

Let n be the finite number of bets the gambler can afford to lose. The probability that the gambler will lose all n bets is q n.

When all bets lose, the total loss is. In all other cases, the gambler wins the initial bet B. Thus, the expected profit per round is.

Thus, for all games where a gambler is more likely to lose than to win any given bet, that gambler is expected to lose money, on average, each round.

The intuition behind the definition is that at any particular time t , you can look at the sequence so far and tell if it is time to stop. An example in real life might be the time at which a gambler leaves the gambling table, which might be a function of their previous winnings for example, he might leave only when he goes broke , but he can't choose to go or stay based on the outcome of games that haven't been played yet.

That is a weaker condition than the one appearing in the paragraph above, but is strong enough to serve in some of the proofs in which stopping times are used.

The concept of a stopped martingale leads to a series of important theorems, including, for example, the optional stopping theorem which states that, under certain conditions, the expected value of a martingale at a stopping time is equal to its initial value.
