The Martingale system is a system of investing in which the dollar value of investments continually increases after losses, or the position size increases with the lowering portfolio size.

The strategy is based on the premise that only one good bet or trade is needed to turn your fortunes around. This technique can be contrasted with the anti-martingale system , which involves halving a bet each time there is a trade loss and doubling it each time there is a gain.

The Martingale system is a risk-seeking method of investing. The main idea behind the Martingale system is that statistically, you cannot lose all of the time, and thus you should increase the amount allocated in investments—even if they are declining in value—in anticipation of a future increase.

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 system is commonly compared to betting in a casino with the hopes of breaking even. Since a gambler with infinite wealth will, almost surely , eventually flip heads, the martingale betting strategy was seen as a sure thing by those who advocated it.

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.

Typically, bookmakers offer the same odds for either outcome, and those vary between 1. You start with a small amount, preferably the table minimum, and keep betting the same until you lose.

When this occurs, double the size of your bet for the next spin. This way, in case you win, you will recover the money you lost on the previous round, and win something extra.

If you keep on losing, keep on doubling your bet — the logic stays the same. As soon as you win, you should restart and bet the smallest amount for the next spin.

Rinse and repeat. In theory, you can go on like this forever, doubling up after every loss and earning a small profit after every win.
