01 · The Math
Break-even Depends on the Payout
A losing trade costs 100% of your stake; a winning one pays only the payout percentage. So you start every session behind, and the win rate you need just to break even is roughly 1 / (1 + payout). That's not pessimism — it's arithmetic, and it reframes what "good" means.
| Payout % | Break-even win rate | Meaning |
|---|---|---|
| 70% | ~59% | Need to win nearly 3 in 5 just to hold |
| 80% | ~56% | The common baseline to clear |
| 85% | ~54% | Higher payout, slightly easier line |
| 90% | ~53% | Better assets/hours lower the bar |
Chase payout, not just wins
A higher payout lowers the win rate you need. Trading better assets and hours can matter as much as being "right" more often — both move you above the break-even line.
02 · The Scam Signal
Why "High Win Rate" Is a Red Flag
Because a small edge above break-even is realistic and unglamorous, sellers inflate the number instead. "90% win rate," "never loses," "guaranteed" — these aren't features, they're warnings. Real results are a modest margin over the break-even line, sustained across a large sample, with losing days in the mix.
03 · Sample & Risk
One Number Is Never Enough
Even a genuinely good win rate is useless without two companions: a large sample(so it isn't luck) and risk management(so a losing streak doesn't end you before the edge shows). Measure it honestly on demo, over hundreds of trades, with a fixed stake and a daily stop.
A high win rate on a small sample proves nothing, and no win rate removes risk — binary options carry a real risk of losing capital, and most traders lose. Judge over many trades, keep a daily stop loss, and trade only what you can afford to lose. Koala S Pro is a tool, not financial advice.

Frequently Asked Questions
What is win rate in trading?
The share of your trades that win, over a sample — 60 wins in 100 trades is a 60% win rate. On its own it's incomplete: it only becomes meaningful alongside the payout percentage and a large enough sample.
What win rate do I need to profit?
It depends on the payout. Because a loss costs the full stake while a win pays only the payout %, you need roughly 1 / (1 + payout) to break even — about 54% at 85%, ~56% at 80%. Profit is consistently above that line.
Is a 90% win rate realistic?
As an advertised, sustained figure — no. It's the calling card of a scam. Real strategies win a modest margin above break-even over hundreds of trades, with plenty of losses mixed in.
Why does sample size matter?
A 70% win rate over 10 trades is noise; the same over 500 trades is signal. Variance makes short samples wildly misleading — judge any strategy only over a large number of trades.
Does a bot improve win rate?
A bot doesn't raise the odds of any single trade — it improves consistency of execution, which protects whatever win rate your strategy genuinely has. It can't turn a losing strategy into a winning one.
