What Is R-Multiple in Trading? (And Why It Beats Win Rate)

R-multiple is one of the most useful numbers a trader can track — and one of the most misunderstood. Once you measure trades in R instead of dollars, your edge becomes obvious in a way win rate alone will never show you.

What "R" actually means

R is your initial risk on a trade — the amount you'd lose if your stop-loss is hit. Your R-multiple is the result of the trade measured in units of that risk, instead of in dollars.

Risk $100 and make $300, and that's a +3R trade. Risk $100 and lose it, that's −1R. The beauty is that R normalises every trade: a +2R win is a +2R win whether you risked $50 or $5,000, so you can compare trades and setups on equal footing.

A worked example

You buy a stock at $50 with a stop at $48, so your risk is $2 per share — that's your 1R. Three outcomes:

• Exit at $56 → gained $6 per share → $6 ÷ $2 = +3R
• Exit at $51 → gained $1 → +0.5R
• Stopped out at $48 → lost $2 → −1R

Notice the share count and dollar amounts don't matter. Whether you bought 10 shares or 10,000, the trade is still +3R — which is exactly what makes R so comparable across your whole history.

Why R beats win rate

Win rate is the number new traders obsess over, and it's deeply misleading on its own. A trader who wins 40% of the time can be wildly profitable; a trader who wins 80% of the time can blow up. The missing piece is how big the wins are versus the losses — and that's precisely what R captures.

Imagine 10 trades, winning only 4:

• 4 winners at +3R each = +12R
• 6 losers at −1R each = −6R
• Net: +6R, despite a 40% win rate

A 40% win rate sounds like a losing trader. In R, they're clearly winning. That's the insight win rate hides and R reveals.

R, expectancy, and your edge

R leads directly to expectancy — your average result per trade, and the truest measure of an edge:

A positive expectancy means each trade is, on average, worth money — so your job becomes simply taking more of the same trades. A negative expectancy means more volume just loses faster, no matter how good a single trade feels.

How to track R without doing maths every trade

To get R, you only need two things recorded on every trade: your initial risk and your result. That's it. If you keep a journal properly (here's how to keep a trading journal), the R-multiple falls out automatically.

Journex computes R-multiple, average R, win rate and expectancy from your trades as you log them, and folds them into a 0–100 Trade Score — so you can watch your edge instead of recalculating it.
