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.
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.

Suppose a gambler has a 63 unit gambling bankroll. 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".A martingale is any of a class of betting strategies that originated from and were popular in 18th-century France.
