Anti-martingale
Definition
The anti-martingale is a money-management approach where the trade amount grows after every win and returns to the base amount after any loss. Unlike martingale, what is at stake is not the deposit but the profit already earned: a streak of losses runs at flat base amounts.
How the approach works
There is one rule: after a win the next trade grows by a multiplier, after a loss it returns to the base amount. The logic is to have the large amounts land on the good stretches while the bad ones pass at minimal risk.
The key difference from chase methods is what exactly is on the line. Martingale builds the amount up after a loss, which means risking the deposit in an attempt to recover what is already gone. The anti-martingale builds up after a win and risks the profit that the same series has just produced. The deposit loses exactly one base trade at a time.
A series of four wins
A $100 base, a 1.5 multiplier, an 85% payout:
| Step | Trade amount | Step profit | Accumulated |
|---|---|---|---|
| 1 | $100.00 | +$85.00 | +$85.00 |
| 2 | $150.00 | +$127.50 | +$212.50 |
| 3 | $225.00 | +$191.25 | +$403.75 |
| 4 | $337.50 | +$286.88 | +$690.63 |
The same four wins at a flat $100 would have produced $340 — half as much. That is the whole point of the approach: identical accuracy of entries, a different result.
But the table has a price, and it sits in the probability. Four wins in a row at a 57% win rate come up in about 11% of attempts, and at 60% in 13%. So you will complete the full series roughly one time in eight to ten and cut it short on the first or second step in the rest, with a far more modest result. The return of the approach cannot be judged by one lucky table — it has to be judged across every attempt, the aborted ones included.
And now the part usually left out. If no series limit is set and the fifth step ($506.25) turns out to be a loss, $184.38 is what remains of the accumulated $690.63. The result is still positive, but a single trade took three quarters of what the series had built. Push the limit one step further and a loss takes more than the series managed to accumulate.
Putting it to work
You can run your own series through the anti-martingale calculator: it computes both variants of growth, shows what has accumulated and, on a separate line, how much a loss on the next step would take. That is the number the limit gets chosen by.
The practical rule is simple: the limit is set before the series starts, not along the way. The temptation of "one more step" arrives exactly at the step where the amount is already large — and a decision made at that moment is not made by arithmetic.
How it differs from a fixed percent
A fixed percent computes the amount from the current deposit, so it moves slowly and without regard to recent results: a run of three wins barely affects the next trade. The anti-martingale reacts sharply and to results only — three wins in a row more than triple the amount.
Hence the difference in use. A fixed percent is the everyday base; it keeps the risk constant. The anti-martingale is an overlay for short stretches where you trust the setup and are ready to put what you have earned on the line. The two combine well: the base amount is a percent of the deposit, and the multiplier works inside the series.
Frequently asked questions
How does the anti-martingale differ from martingale?
In the direction of growth and in what is on the line. Martingale raises the amount after a loss, trying to win the loss back — the risk to the deposit grows. The anti-martingale raises the amount after a win, accelerating the series — only the money earned in that series grows. A loss in the anti-martingale costs exactly one base trade.
Is a series limit necessary?
Essential. Without a limit the series always ends with a loss on its largest amount, and that final step eats what was accumulated. A limit — four wins, say — locks the profit in and returns the amount to the base; it is what turns the approach from a pretty idea into a working rule.
Does the anti-martingale make a losing strategy profitable?
No. No progression creates an edge — it only redistributes the one you already have. If your share of winning trades sits below the breakeven threshold, the anti-martingale merely changes the shape of the equity curve, not its direction.
