Calculate how many consecutive losses your balance can sustain
| # | Trade Size ? | Cumulative ? | Loss Probability ? |
|---|
Enter your balance, your first stake, the payout you receive on a winning trade and your expected win rate. Each row shows the stake you would need after that many losses in a row, the total you would have risked, and the chance of losing that many times in a row. Green rows fit in your balance; red rows do not.
Classic martingale doubles the stake because an even-money bet pays 100%. A binary option pays less than a loss costs: in our IQ Option Practice trades of 2 October 2026, winning trades paid 82–88%. To recover earlier losses at an 85% payout, every stake must be about 2.18 times the previous one, so your balance runs out sooner. Set the payout field to the payout your platform shows before you trade.
The bust probability is the chance that one martingale sequence loses more times in a row than your balance can cover. It looks small, but you repeat the sequence every time you start again, so over hundreds of sequences a losing streak of that length becomes likely. One such streak wipes out the small wins before it.
Risk warning: martingale does not change the odds of a trade; it only makes the stake grow after losses. Practise on a demo account first and never risk money you cannot afford to lose. Read our martingale strategy test on IQ Option and the pros and cons of martingale.
