Win Rate vs Risk-Reward Ratio Explained

Many new traders chase a high win rate. It feels good to be right often. But win rate is only half of the story. The other half is how much you make when you win compared with how much you lose when you are wrong. This article shows how the two fit together, with small numbers you can check yourself.

Two numbers, one question

Win rate is winning trades divided by all decided trades. 6 winners out of 10 is 60%.
Risk-reward (RR) compares what you aim to win with what you risk. Risking 50 to make 100 is 1:2.

Neither number tells you whether a strategy makes money. The question is whether the two together leave you with a positive average result per trade. That average is called expectancy.

The break-even win rate

For a fixed reward-to-risk ratio, there is a win rate below which you lose money. Ignoring costs, it is:

Break-even win rate = 1 ÷ (1 + reward-to-risk)

Reward : risk	Break-even win rate
1 : 1	50%
1.5 : 1	40%
2 : 1	33%
3 : 1	25%
0.5 : 1	67%

So a trader who wins only 40% of the time can be profitable with a 2:1 average, while a trader who wins 70% of the time can lose money if the average winner is much smaller than the average loser. Commission and swap move these lines up a little, so use your net results when you check.

Two traders, same account

Trader A: high win rate, small wins

Wins 70% of trades, makes +0.4R on a win and loses -1R on a loss. Per 10 trades: 7 × 0.4 = +2.8R and 3 × -1 = -3R. Result: -0.2R, or -0.02R per trade. Most trades were winners and the account still shrinks.

Trader B: low win rate, bigger wins

Wins 40% of trades, makes +2R on a win and loses -1R on a loss. Per 10 trades: 4 × 2 = +8R and 6 × -1 = -6R. Result: +2R, or +0.2R per trade. Six of ten trades lost, and the account grows.

These are examples, not forecasts. They only show that you need both numbers before you judge a method.

The trap of the tight target

A common habit is to take profit very early so that the trade feels safe, while the stop stays wide. Your win rate goes up, but your average win shrinks against your average loss. If you notice that your winners are small and your losers are large, the fix is usually not a new strategy. It is looking at where you exit and why.

The trap of the wide target

The opposite mistake is setting a 4:1 target that price rarely reaches. Your win rate falls, losing streaks get longer and it becomes hard to follow your own rules. A reward-to-risk ratio only counts if the market gives it to you often enough. Test it on real trades, not on a guess.

How to check both in ICC Zillas

Dashboard: the trade win % card, the avg win / loss card and the profit factor card sit side by side. Read them together. The guide explains each card.
Reports: open the Setups or Playbooks report and compare win rate with average win and loss per setup. One setup may win often with small gains, another may win rarely with big gains. Judge each one on its own numbers.
R multiple report: shows how your trades spread across results in R, so you can see if you often cut winners short.
Trade replay with MAE / MFE: shows how far price went in your favour after entry, so you can see if your targets are too tight or too wide.

Start your own check by importing your history into the app, then write down three numbers: win rate, average win, average loss. Do the break-even maths once. It often changes what you work on.

Simple rules to take away

Never judge a strategy by win rate alone.
Never judge it by risk-reward alone either.
Use at least 30 to 50 trades before you trust the numbers, and update them as you trade.
Count costs. Small wins suffer most from commission and spread.
