An R-multiple expresses a trade's result in units of the risk you took, where 1R is the amount you risked on that trade. A trade that makes twice your risk is plus 2R; one that hits the stop is minus 1R. By measuring everything in R, results from different position sizes and account balances become directly comparable.
Target audience: Traders who track dollars and want a normalized unit that makes setups, streaks, and edge legible.
An R-multiple expresses a trade's result in units of the risk you took, where 1R is the amount you risked on that trade. A trade that makes twice your risk is plus 2R; one that hits the stop is minus 1R. By measuring everything in R, results from different position sizes and account balances become directly comparable.
Dollars hide the truth because every trade is a different size; R reveals it because the unit is always your own risk. Thinking in R lets you judge a setup by its reward-to-risk, track expectancy across a sample, and see exactly how a losing streak accumulates. It also reframes targets and stops: a target is worth its R, a stop costs 1R, and the only question that matters becomes whether your wins in R outweigh your losses in R over time.
R is defined per trade as the distance from entry to stop, in money: the amount you lose if the stop is hit. Every other outcome is measured against it. Make twice your risk and the trade is plus 2R; lose the planned amount and it is minus 1R; get stopped for half before a partial exit and it is minus 0.5R. Because R is anchored to your own risk, a 2R win on a tiny account and a 2R win on a large one are the same achievement in the only unit that matters.
Before entering, the potential target measured in R tells you the trade's shape. A setup with a stop 1 wide and a target 2 away offers 2R; the same target with a 0.5 stop offers 4R. Thinking this way stops you from taking trades whose reward is small relative to the risk, and it makes the entry decision concrete: you are not buying a price, you are buying a known number of R for a defined 1R of downside.
Plotting trades as a running total of R turns a string of outcomes into a clear equity-in-R curve. A normal losing streak shows up as a gentle decline of minus 1R steps; an oversized or revenge trade shows up as a sharp drop of minus 2R or worse that the curve struggles to recover. Seeing the sequence in R makes it obvious that the danger is not the routine losses but the moments you broke the risk unit and took a multi-R hit.
Because R normalizes for size, a sample of trades in R can be summed and averaged into a single number: average R per trade, which is expectancy. Dollars cannot do this honestly when each trade was a different size. R is the bridge from individual trades to a measurable edge: judge the system by its average R over many trades, and judge each trade by whether it was taken and managed to protect that average.
Trade A risks 100 dollars and makes 200; trade B risks 400 and makes 600. In dollars B looks better. In R, A is plus 2R and B is plus 1.5R, so A was the stronger trade per unit of risk. Measuring in R, not dollars, ranks them correctly and keeps a small disciplined win from being overshadowed by a larger but less efficient one.
A trader logs a sequence: minus 1R, minus 1R, plus 1.4R, minus 1R, then a pressure trade of minus 2.6R. The first four are a normal run that barely dents the equity-in-R curve; the fifth, an oversized break of the unit, drops the curve sharply. Read as a sequence in R, it is plain that the streak was survivable and the single multi-R trade was the real damage.
Judging trades in dollars when each had a different position size
Taking setups whose reward is small in R relative to the 1R risk
Letting a winner give back so much it no longer counts as a positive R
Treating a minus 2R break of the unit as just another loss
Not logging R per trade, so the edge never becomes measurable

Take your last set of trades and re-express every result in R, then total the sequence.
