How to read your risk/reward ratio
Risk/reward compares how much you stand to lose against how much you stand to gain on a single trade, expressed as a ratio like 1:2. A 1:2 ratio means you're risking one dollar to potentially make two. It says nothing about your odds of winning — that's a separate number (your win rate) that you track from your own trade history.
The two numbers work together. A strategy with a 1:1 ratio needs to win more than half its trades to be profitable after costs. A strategy with a 1:3 ratio can be profitable winning only a third of the time. Neither ratio is inherently "correct" — it depends on which one matches how your setup actually performs.
