Risk-Reward Ratio
The ratio comparing how much a trader stands to lose if a trade fails against how much they stand to gain if it succeeds, used to judge whether a setup is worth taking.
The risk-reward ratio compares the distance from entry to the stop-loss (the risk) against the distance from entry to the profit target (the reward). A trade risking one dollar to make three has a 1:3 risk-reward ratio. It is calculated before entry from the planned stop and target, and is one of the core filters disciplined traders apply to every setup — alongside position sizing, which is derived from the risk side of the same trade.
The ratio interacts directly with win rate to determine profitability. A strategy that wins only 40 percent of the time is still profitable at 1:3 risk-reward, because the winners more than cover the losers; conversely, a strategy that wins 70 percent of the time can still lose money at 1:0.5. Many traders require a minimum ratio — commonly 1:2 or better — so they need to be right less than half the time to come out ahead over a series of trades.
The ratio's main limitation is that the reward is hypothetical — the target may never be reached — while the risk is real and frequently hit. A seductively high ratio like 1:10 often means the target is unrealistically far away, lowering the true probability of success; the honest version weights the ratio by the probability of each outcome, which is the trade's expected value. Risk-reward is most useful combined with a realistic win-rate estimate and sensible stop placement, not as a number to maximize in isolation.
