A unit that measures profit or loss in multiples of the initial risk taken on a trade — normalizes performance across different position sizes.
An R-multiple is the result of a trade expressed in multiples of the initial risk. If you risked $100 on a trade and made $300, that's a +3R trade. If you risked $100 and lost $50, that's a -0.5R trade. The R unit normalizes performance across trades of different sizes.
The magic of R-multiples is that they let you compare trades directly. A 3R win on a $100 risk and a 3R win on a $1,000 risk are equally valuable for evaluating skill. The dollar amounts differ but the SKILL DEMONSTRATED is identical. R-multiples are the language pros use to talk about performance.
Expectancy is also expressed in R. A strategy with +0.5R expectancy means each trade returns half a unit of risk on average. Over 100 trades, that's +50R total. With 1% risk per trade, that's a 50% return.
Van Tharp, the trading psychologist, popularized R-multiples in his books and training. Most modern professional trading desks now report performance in R-multiples first, dollars second.
