Where the idea comes from
The R-multiple concept was popularised by trading psychologist Van K. Tharp. The core idea is that money results are a poor way to judge trades: a $500 profit means something very different on a trade that risked $100 than on one that risked $2,000. Dividing by the initial risk removes position size from the picture.
How to read R-multiples
- −1R is a normal, well-executed loss: the stop was hit at the planned price.
- Below −1R signals an execution problem: slippage, a gap, or a stop that was moved or ignored.
- 0R to +1R is a small win or scratch, often from exiting early.
- +2R and beyond are the trades that pay for several losses.
Convert any trade with the R-multiple calculator, which handles long and short trades and subtracts fees.
Your R distribution is your strategy
Record every trade as an R-multiple and plot them, and you get a picture of how your strategy really behaves. Two systems with the same total profit can look completely different:
- A tight cluster of −1R losses and +1R to +2R wins — steady, psychologically easy, sensitive to costs.
- Many −1R losses and a few +8R to +15R winners — long losing streaks, with results that hinge on not missing the outliers.
Knowing which shape you trade tells you what drawdowns to expect and which mistakes are most expensive. Cutting a +10R winner at +2R hurts the second system far more than the first.
From R-multiples to expectancy
The average of your R-multiples is your expectancy per trade. If 50 trades average +0.3R, each trade has returned 30% of what it risked. Combine expectancy with how many trades you take, and you have a direct estimate of performance:
At +0.3R, 100 trades a year and $200 risk per trade, that's roughly $6,000 — before considering variance. The compound growth calculator shows how much results can vary around that figure.
Pitfalls when tracking R
- Using the final stop instead of the initial stop. Trailing a stop to break-even doesn't make the initial risk zero.
- Leaving out trades without stops. These are usually the worst trades. Excluding them makes expectancy look better than it is.
- Drawing conclusions from small samples. With 20 trades, one big winner can dominate the average.
