Martingale vs flat staking — run the numbers before you choose
Martingale wins most sessions and loses every account eventually. Flat staking loses more sessions and keeps you trading. The difference is not opinion; it is a capital requirement that grows exponentially against a bankroll that does not.
- Eight consecutive losses on a $5 base requires $1,275 already committed and $1,280 for the next trade.
- Broker stake caps mean the recovery trade is often not even placeable.
- Flat staking survives streaks that erase martingale accounts.
What a losing streak actually costs
A nine-loss streak is not exotic. At a 55% win rate it appears roughly once every few hundred trades — well within a single month of active trading. Martingale requires $2,555 of committed capital to still be in that hand; flat staking has spent $90.
| Loss # | Martingale stake ($5 base) | Cumulative risked | Flat stake (1% of $1,000) |
|---|---|---|---|
| 1 | $5 | $5 | $10 |
| 3 | $20 | $35 | $10 |
| 5 | $80 | $155 | $10 |
| 7 | $320 | $635 | $10 |
| 9 | $1,280 | $2,555 | $10 |
Payout below 100% breaks the doubling logic
Classic martingale assumes a win returns your full stake plus an equal amount. Binary payouts are 70–95%, so doubling does not fully recover the sequence — you need to more than double, which accelerates the capital requirement further. Any martingale calculator that ignores payout is showing you a fantasy.
What to do instead
1–2% per trade, recalculated weekly. Dull and durable.
Stake rises only as the balance rises, never after a loss.
Mathematically optimal sizing given a known edge — use half-Kelly in practice.
Frequently asked questions
+Why does martingale feel like it works?
Because it wins the majority of sessions. The rare failure is large enough to erase all of them plus the account.
+What about a 1.5x multiplier instead of 2x?
It slows the failure, it does not remove it. The capital curve still grows exponentially against a fixed bankroll.
+Is compounding safer than martingale?
Yes. Compounding increases size after wins as the balance grows; martingale increases size after losses as the balance shrinks.
+How do I model my own numbers?
Use the martingale calculator with your real payout and base stake, then look at required capital, not projected profit.
