DEFINITION
Risk-Reward Ratio
The ratio of potential profit to potential loss on a single trade. A 1:3 RR trade risks $1 to make $3. Strategies with RR above 1:2 can be profitable even with win rates below 50%.

R-Multiple
A normalized unit measuring trade outcome as a multiple of initial risk. If you risked $100 and made $300, that's a +3R trade. Allows comparing trade quality regardless of position size or account size.
Win Rate
The percentage of trades that close profitably. A common misleading metric — high win rates with low RR can be less profitable than low win rates with high RR.
Edge
A statistical advantage in a trading strategy that produces positive expected value over a large sample of trades. Without an edge, even perfect discipline cannot produce long-term profitability.
