How to read a risk-reward ratio
A ratio is a question, not an answer. Here is how to turn it into a decision.
A reward-to-risk ratio tells you the shape of a trade: how much it stands to make against how much it risks. What it never tells you, on its own, is whether to take the trade. That depends on a second number — your win rate — and the two only mean something together. This guide is about reading them as a pair.
Step one: get the ratio
Reward distance over risk distance. Entry to target, divided by entry to stop. The calculator does it as you type, but the value of doing it by hand once is seeing how sensitive the ratio is to the stop: a stop moved a fraction closer to the entry can swing a 2:1 into a 3:1 without changing the idea at all, which is exactly why where you place the stop matters more than where you place the target.
Step two: read off the break-even win rate
One divided by one-plus-the-ratio. This is the win rate at which the trade type breaks even. It is the single most useful thing a ratio gives you, because it converts an abstract “3:1 sounds good” into a concrete “I need to win more than a quarter of these.” If your honest, measured win rate on trades like this clears the break-even line with room to spare, the ratio is working for you. If it does not, a beautiful ratio is still a losing trade.
The number a ratio is really telling you
A reward-to-risk ratio is not a verdict on a trade; it is a statement about how often you are allowed to be wrong. Read it backwards and it hands you a break-even win rate — the share of trades you have to win, at that ratio, just to come out flat before costs. The arithmetic is one line: break-even win rate equals one divided by one-plus-ratio. At 1:1 you need to win more than half the time; at 2:1 you can be wrong roughly two times in three and still tread water; at 3:1 a quarter is enough.
That is why a bare win rate is close to meaningless on its own. “I win 80% of my trades” is impressive until you learn each loser is four times the size of each winner — at which point the account bleeds. The calculator on this site shows the break-even win rate next to every ratio for exactly this reason: the two numbers only mean something together. A favourable ratio with a win rate comfortably above its break-even line is an edge; a spectacular win rate at a punishing ratio is a slow leak waiting for a bad streak.
The test to carry away: never judge a ratio without asking what win rate it requires, and never judge a win rate without asking what ratio it was earned at.
Step three: check the levels are real
This is the step the maths cannot do for you, and the one most traders skip. A ratio is only as honest as the entry, stop and target it was computed from. If you read those levels off someone else's call, ask the question the whole scorecard is built around: were they fixed in public before the trade resolved? With the pick you can confirm a past setup against its Bitcoin receipt, which means the 3:1 it showed was a 3:1 at release, not after the stop was quietly widened. A ratio you cannot trace to fixed levels is a number someone wants you to believe.
Net: a ratio plus its break-even win rate plus a check that the levels were real. Skip any one and the ratio is decoration. The next guide turns the trusted ratio into an order.
