What Is an R-Multiple in Trading?
Category: Journaling & metricsChinese: R 倍数
Short definition
An R-multiple is a trade's profit or loss divided by the amount initially risked on it — the entry-to-stop distance times position size — so results are stated in units of risk (R) instead of currency.
What it means
R turns every trade into the same unit. Define 1R as the money you would lose if the stop was hit, calculated when you entered. A trade that risks 100 and closes at +250 is a +2.5R winner; a trade that risks 500 and closes at +400 is the same +0.8R. Currency results hide the fact that the second trader was right by more; R does not.
The unit exists because raw P&L answers the wrong question. Two traders can show the same dollar profit while one took five times the risk to get it. Quoting in R separates the quality of decisions from the size of the account, which is exactly what a review needs — and what sharing results honestly requires, since a +3R day is meaningful on a 2,000 account and on a 2,000,000 one.
R also feeds the arithmetic of survivability: average R-multiple per trade, multiplied by trade frequency and the fraction of winners, is what determines whether a strategy pays after costs. A system that averages +0.2R per trade over 100 trades is +20R; the same system dragged down by oversized -3R rule breaks is a different, worse system, whatever the win rate says.
What R-exposure looks like in a log
Once entries carry a stated stop and size, the R view of your trading becomes mechanical:
- Every entry line records planned risk in currency and in % of equity — which makes the R-multiple computable at exit, not estimated.
- Losing trades cluster at -1R (the stop did its job) instead of scattering to -2R, -3R (stops moved or ignored).
- Wins are not all smaller than losses: the R-distribution of winners reaches at least +1.5R somewhere, or the math of costs cannot be covered.
- Rule-break entries are quoted in R too — an oversized unplanned loss shows up as a -4R outlier that no strategy test predicted.
- Weekly review averages R per trade by setup type, so you learn which setup earns its costs, not which setup had a lucky week.
Logging trades in R
The habit is three fields per trade, written at entry, not reconstructed at exit:
- 1.At entry, write stop price and position size; compute 1R in currency and as % of equity before confirming the order.
- 2.At exit, compute the R-multiple (net of commissions) and store it with the setup name — this is the number the review sorts by.
- 3.Cap the outlier risk: if a single trade's planned risk exceeds your normal 1R (for example, doubled size after a loss), log why; those rows are where discipline review lives.
- 4.Review the R-distribution weekly: average R, worst R, and the count of trades that were never authorized. Expect months of data before per-setup averages mean anything.
- 5.Practice the computation itself in simulation until placing the stop-first order is automatic — R journaling fails mostly because entries without stops cannot be quoted in R at all.
Frequently asked questions
What does 2R mean in trading?
2R means a profit equal to twice the amount risked on that trade. If you risked 200 (entry-to-stop distance times size) and closed the trade at +400, that is +2R. Losses quoted in R work the same way: losing exactly what you planned to risk is -1R.
How is an R-multiple different from risk-reward ratio?
Risk-reward ratio is the plan, stated before entry (target distance divided by stop distance). R-multiple is the realized outcome, computed after exit. A trade can be planned at 1:2 and realized at +0.6R — the gap between planned and realized R is itself a review metric.
Can I use R-multiples without a stop-loss order?
Not meaningfully. R is defined by initial risk, which requires knowing where the trade is wrong and what size makes that wrongness cost 1R. Entries without a stated invalidation point have no denominator — which is why the first habit of R journaling is writing the stop before the entry.
