The ratio of a trade's potential profit to its potential loss.
The risk-reward ratio (RR) is the single most important measure of a setup's quality. A 1:2 RR means: you risk 1 dollar to make 2. With 1:3 RR, a 25 % hit rate is already enough for a profitable system. Rule of thumb: setups below 1:1.5 RR only pay off with a high hit rate (>60 %). Suna AI Vision shows the RR per AI answer prominently in the comparison table.
Long trade with 30 pip stop and 90 pip target = 1:3 RR. Still profitable at 40 % hit rate.
