How Many Losses in a Row Can a 60% Win Rate Have?
A 60% win rate still produces ugly streaks on a schedule, and most evaluation accounts are sized as if it does not.
You win six trades out of ten. The account still hit the max loss limit, and you are paying for another reset. Nothing broke. Here is the math, then a way to size your next eval so one ordinary streak does not end it.

The odds of a losing streak at 60%
Take a trader who wins 60% of trades and loses 40%, with trades independent of each other. The chance of at least one run of consecutive losses somewhere in a stretch of trades is below. These are exact calculations, not simulations.
| Run of losses | In 20 trades | In 50 trades | In 100 trades |
|---|---|---|---|
| 3 in a row | 56% | 89% | 99% |
| 4 in a row | 25% | 54% | 80% |
| 5 in a row | 10% | 26% | 46% |
| 6 in a row | 4% | 11% | 21% |
| 8 in a row | 1% | 2% | 4% |

Read the 50-trade column. Over a typical evaluation month, four losers in a row is more likely than not. Five in a row happens about one time in four. Those streaks are ordinary for this win rate.
Why the win rate hides the risk
Win rate says how often trades close green. It does not say how big the losers are relative to your account limit. Two traders can both win 60% of the time. One risks a small slice per trade and shrugs off a streak of five. The other risks a large slice and is out after three.
The streak table tells you how many losers to expect. Your max loss rule tells you how many you can afford. The gap between those two numbers is where evaluations die.
Turn the max loss into losers of room
Use this example, with made-up round numbers to show the method. Swap in your own firm's rule.
- Account size 50,000 dollars
- Max loss limit 2,000 dollars (example, check your firm's actual rule)
- Risk per trade 500 dollars
Divide the limit by the risk per trade. 2,000 divided by 500 is 4 losers of room. Four straight losses and the evaluation is over.
From the table, four losers in a row at a 60% win rate shows up in about 54% of 50-trade stretches. At that size, a normal streak is enough to end the attempt.
Now cut risk per trade to 250 dollars. The room doubles to 8 losers. Eight in a row at 60% shows up in about 2% of 50-trade stretches. Same strategy, same win rate, a very different chance of survival.
This simple version only counts consecutive losers and ignores wins in between. Real evaluations have trailing drawdowns, daily loss limits and uneven winners, so the true picture is more complicated. A simulation that uses your actual win rate, reward to risk and firm rule is the better check. The direction does not change. Smaller size buys room.
See how much cushion an account needs.
A quick way to pick the size
- Write down the firm's max loss in dollars.
- Decide how many losers in a row you want to survive. If you want a streak of 6 to be survivable, that is about a 1 in 9 event in 50 trades at 60%.
- Divide the max loss by that number. That is your risk per trade ceiling.
- Check it against your reward to risk and your daily loss limit.
If the answer is smaller than you want to trade, trade the smaller size.
What about Kelly?
Kelly sizing maximizes long-run growth and ignores your firm's wall. On an evaluation account, size to the cushion first, then see whether a Kelly fraction fits inside it. We cover that order in Kelly versus the drawdown wall.
You can also simulate your own win rate.
FAQ
Is a 60% win rate good?
It depends on reward to risk. A 60% win rate with winners smaller than losers can still lose money. The win rate alone does not tell you.
How many losing trades in a row is normal?
At a 60% win rate, 3 or 4 in a row is routine over 50 trades, and 5 in a row happens about one time in four (calculation above).
Does the table apply to my strategy?
Only if your real win rate is near 60% and trades are roughly independent. Use your own logged win rate. A short sample can mislead.
Can I still pass with 4 losers of room?
Yes, but you are relying on not having a normal streak. Smaller size or a firm with a wider limit changes that.
Is this financial advice?
No. It is educational math. RangeSight is not affiliated with any prop firm.

Key Takeaway
A 60% win rate still produces 4 losses in a row more than half the time over 50 trades. See the odds and size your next eval so one streak does not end it. RangeSight uses Monte Carlo simulation to show the chance of ruin, the chance of a drawdown, and the range of outcomes. It is not financial advice.
This explains the concept.
But outcomes vary in practice. The same strategy can produce a 40% gain or a 30% drawdown depending on trade sequencing and market conditions.
