What Is a Good Win Rate for a Trader?

By Sam Davila on 2026-07-13 - 4 min read

A good win rate is whatever win rate makes your expectancy positive. That is the entire answer, and everything after it is arithmetic. Win rate on its own tells you nothing about whether a strategy makes money: a trader who wins 40% of the time can comfortably out-earn one who wins 70% of the time, and the gap is not close.

The number that actually matters

Expectancy is what you earn per trade, on average, once your wins and losses are weighted by how big they are. Win rate multiplied by average win, minus loss rate multiplied by average loss.

Run two traders through it. The first wins 40% of her trades. She makes $300 when she is right and loses $100 when she is wrong:

0.40 × $300 − 0.60 × $100 = $60 per trade

The second wins 70% of his trades, a figure most traders would envy. But he makes $100 when he is right and loses $200 when he is wrong:

0.70 × $100 − 0.30 × $200 = $10 per trade

Across a hundred trades she clears $6,000 and he clears $1,000. She is wrong nearly two times out of every three, and she earns six times what he does. Her win rate is worse in every sense except the one that pays.

A high win rate is easy to manufacture

Win rate feels like skill. It is the number a trader quotes at dinner, and it is the number that survives in memory long after the size of the losses has faded. The problem is that you can raise it any afternoon you like: widen your stop, take profit earlier, and watch the percentage climb. Nothing about the strategy improved. You moved money out of the average-win column and into the average-loss column, where it is harder to look at.

That is the trade that quietly ruins accounts. A strategy that wins nine times out of ten and gives back every one of those gains on the tenth is a losing strategy in a winner's costume. The market does not pay you for being right. It pays you the difference between what you take when you are right and what you surrender when you are wrong.

The floor is lower than you think

The relationship runs in both directions, and it is worth knowing where the floor sits. If your average win is twice the size of your average loss, you need to win only 34% of your trades to start turning a profit. Push your reward-to-risk further and the required win rate drops again. Take profits the same size as your stops and you need better than half your trades to go your way simply to break even, before costs.

So where do the professionals land? In the 50-55% range. Not because 55% is a magic number, but because a durable edge does not have to be dramatic — it has to be repeatable, and it has to be sized correctly. Anyone advertising 90% should be asked, immediately, what their average loss looks like.

Track three numbers, not one

Stop treating win rate as a headline. Track it alongside your average win and your average loss, and never look at one without the other two. Any single number is noise. The three together are a strategy. If you cannot state all three from memory, you do not know whether your system makes money — you know only how it has been making you feel.

Then watch what your own behaviour does to those three numbers, because that is where most edges die. Sentient Logic reads your trade history for the psychology underneath it: revenge trading after a loss, size creep on a hot streak, the entries you took because you were bored. It also lets you tag the emotional state behind a trade, so the cost of your angry entries shows up as a figure sitting next to your planned ones. An honest average loss is built out of exactly those trades — the ones that are easiest to leave out of the story you tell yourself.

A 40% win rate is not a problem to be fixed. It is a fact to be sized around.
