Reading the R-multiples: "2.5R" means the target pays 2.5× what you'd lose on stop-out. A trade only needs to win ~28% of the time at 3R to break even. Aim for 2R+ on planned targets. Cards turn orange when R drops below 1.0 — meaning you're risking more than you're trying to make, which is usually a mistake.
