How to read a win rate
A win rate is the most quoted number in the signal business and the most misread. Here is how to turn it from a headline into evidence.
A win rate is simply the share of calls that closed in profit. On its own it tells you almost nothing, because two numbers are missing: how many calls it is the share of, and how big the winners were against the losers. Supply those and the win rate becomes useful; quote it without them and it is decoration.
First, demand the denominator
“90 percent win” with no count beside it could be nine of ten cherry-picked screenshots, and there is no way to tell — which is exactly why it is quoted that way. Compare that with the worked example's same-session figure: 67.5 percent across 308 calls in 2026. The 308 is the denominator. With it, the percentage becomes something you can interrogate — roughly 208 of those 308 calls closed green and the rest did not — rather than a number floating free of any total. A lower win rate with a denominator beats a higher one without it, every time, because the count is the part a service cannot inflate without lying outright.
Then, frame it with reward-to-risk
Even a true win rate can mislead, because it says nothing about the size of wins versus losses. A strategy that wins 40 percent of the time but makes three times as much on its winners as it loses on its losers comes out well ahead; a strategy that wins 80 percent of the time but loses five times as much on its rare losers can bleed to nothing. This is why the entry, target and stop matter so much: they let you estimate the reward-to-risk that the win rate alone hides. Always read the percentage and the reward-to-risk together.
The questions to ask of any win rate
- Out of how many calls — and are the losing calls counted in?
- Over what continuous period, and does it skip the bad stretches?
- How big is an average winner against an average loser?
- Is there a drawdown figure alongside it, or only the upside?
The takeaway: a win rate with no denominator is marketing; a win rate with a denominator and a reward-to-risk behind it is evidence. Ask “out of how many, and how big were the losers?” before you let any percentage impress you.
