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.

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

However, the exponential growth of the bets eventually bankrupts its users due to finite bankrolls. Stopped Brownian motion , which is a martingale process, can be used to model the trajectory of such games.

The term "martingale" was introduced later by Ville , who also extended the definition to continuous martingales.

Much of the original development of the theory was done by Joseph Leo Doob among others. Part of the motivation for that work was to show the impossibility of successful betting strategies in games of chance.

A basic definition of a discrete-time martingale is a discrete-time stochastic process i. That is, the conditional expected value of the next observation, given all the past observations, is equal to the most recent observation.

Similarly, a continuous-time martingale with respect to the stochastic process X t is a stochastic process Y t such that for all t.

It is important to note that the property of being a martingale involves both the filtration and the probability measure with respect to which the expectations are taken.

These definitions reflect a relationship between martingale theory and potential theory , which is the study of harmonic functions.

Given a Brownian motion process W t and a harmonic function f , the resulting process f W t is also a martingale.

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.

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.

Archived PDF from the original on 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 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.
