Making $450 on a trade can be excellent or mediocre, depending on how much you risked to make it. The R multiple removes the ambiguity: it divides the result by the initial risk and tells you how many times that risk you won or lost. Here is how to calculate it on index futures, what to do with the awkward cases and which statistics change once you measure in R.
What R is and how the multiple is calculated
R is the initial risk of the trade, in dollars: what you would lose if price went from your entry to the stop you set when you entered. In futures it comes from the stop distance, the point value and the number of contracts:
R = stop distance (points) × point value × contractsR multiple = net result ÷ R
Example: long 1 ES with the stop 6 points below. ES is worth $50 per point, so R = 6 × 50 × 1 = $300. You exit 9 points higher: $450 gross. With a $2.50 round turn commission, purely as an example, net is $447.50 and the multiple is 447.50 ÷ 300 = +1.49R. If the stop gets hit instead, you lose $302.50: −1.01R.
In ticks it is the same math: stop ticks times tick value ($12.50 on ES, $1.25 on MES, $5 on NQ, $0.50 on MNQ). It is the same number you use before entry to decide your position size.
The same trade in ES, MES, NQ and MNQ
One idea in four contracts at different sizes, with hypothetical round turn commissions of $2.50 per mini and $0.60 per micro:
| Contract | Contracts | Stop | R | Result | Net P&L | R multiple |
|---|---|---|---|---|---|---|
| ES ($50/point) | 1 | 6 points | $300 | +9 points | +$447.50 | +1.49R |
| MES ($5/point) | 5 | 6 points | $150 | +9 points | +$222.00 | +1.48R |
| NQ ($20/point) | 1 | 24 points | $480 | +36 points | +$717.50 | +1.49R |
| MNQ ($2/point) | 4 | 24 points | $192 | +36 points | +$285.60 | +1.49R |
In dollars, $222 to $717.50; in R, the same trade. That is why R is the unit for comparing a 50K account trading MES with a 150K account trading ES, a month of wide stops with a month of tight ones, or the same position copied into five prop firm accounts. Dollars measure size; R measures the decision. The only difference, +1.48R on MES, is commissions, which weigh more on micros, as the comparison of micros and minis explains.
No stop and moved stops
One rule settles almost every case: R is the risk at the moment of entry and it never changes afterward, whatever you do with the stop.
- Stop moved to break-even or trailed. R stays the initial one. Closing at break-even after raising the stop is 0R minus commission (−0.01R in the ES example), not an avoided loss.
- Widened stop. R does not change either. If you move the ES stop from 6 to 10 points and it gets hit, you lose $502.50: −1.68R. That ugly number is exactly what you want to see, because it puts a figure on the mistake; recalculating R from the new stop would erase it.
- No stop. There is no real R. The least bad option is your plan's base R plus a "no stop" tag: with a $125 base R, losing $310 without a stop is −2.48R. Do not use MAE or the result as the denominator, or every loss would come out at exactly −1R.
Scaling in and scaling out
Scaling out. R is the risk of the full position and the result is the net sum of all exits. With 3 MES and an 8-point stop, R = 3 × 8 × $5 = $120. You close one contract at +8 points (+$40) and two at +24 (+$240): $280 gross, $1.80 in commissions, $278.20 net, +2.32R. That is one trade with one multiple, not three; if your platform splits it into several rows, add them up before dividing.
Scaling in. R is the maximum risk the position ever carried: the sum, contract by contract, of each entry's distance to the stop times the point value. An MNQ long with 2 contracts on the first entry, 2 more ten points lower and the stop 20 points below the first: if both tranches fill, R = 2 × 20 × $2 + 2 × 10 × $2 = $120; if only the first fills, R = $80. If you add to a winner with the stop already above your entry, R is still the largest risk the position carried, almost always the initial one.
Net R and gross R
Gross R divides P&L before commissions; net R, after. Net is what your account reflects, and what a prop firm that measures net sees. The difference is negligible with wide stops and huge with tight ones:
- 1 ES with a 6-point stop: R = $300; a $2.50 commission is 0.008R per trade.
- 1 MES with a 2-point stop: R = $10; a $0.60 commission is 0.06R per trade, 6R every hundred.
A scalping setup with a gross expectancy of +0.05R and a cost of 0.06R per trade loses money even though its gross statistics say otherwise. One more convention: to work out contracts you usually add commission to the per-contract risk; for the multiple, the usual approach is to keep the denominator as the stop distance and subtract commission from the result. Both are valid; mixing them is not.
Expectancy and statistics in R
Expectancy in R is the average R multiple across all trades. It is equivalent to the formula in the guide to setups and expectancy: win rate times average win in R minus loss rate times average loss in R. With 22 winners averaging +1.8R and 18 losers averaging −1.1R over 40 trades, +0.495R per trade. The average hides the shape, though; grouping R multiples into buckets shows which trades produce it (hypothetical example, 50 trades):
| R bucket | Trades | What it usually means |
|---|---|---|
| Worse than −1.2R | 3 | Widened stop, no stop or news slippage: review each one |
| −1.2R to −0.8R | 17 | Stop respected: the loss the plan expects |
| −0.8R to 0R | 6 | Early exits: rule or fear? |
| 0R to +1R | 8 | Small wins: target or nerves? |
| +1R to +2R | 11 | The bulk of the setup |
| Better than +2R | 5 | The ones that pay the bills |
The other statistic that changes meaning is your worst streak, the largest peak-to-trough drop. In dollars it depends on the size you traded at the time; in R it compares with your cushion. With a $2,500 cushion and a $125 R you have 20R: a historical streak of −7.3R already used more than a third of it, and the next one can be worse. That is the number a risk ladder is designed around. And to see why your losers land at −1R and your winners rarely pass +1.5R, the guide to MAE and MFE looks inside each trade.
Common mistakes
- Recalculating R from the final stop. It turns every widened stop into a clean −1R.
- Defining R from the target or the result. R comes from the stop, never from what you hoped to make.
- Dividing gross P&L. With tight stops, commission can flip the sign of your expectancy.
- Mixing units. One contract's risk against three contracts' result triples the multiple.
- Counting the same position several times. Five accounts with the same entry are one decision.
- Leaving out no-stop trades. They are usually the worst; without them, your expectancy belongs to a more disciplined trader than you.
Frequently asked questions
Does a −1R loss mean I respected my stop?
Almost always. A loss at the stop comes out slightly worse than −1R because of commission and, sometimes, a tick of slippage: −1.01R or −1.05R are normal. What deserves a review is any loss worse than −1.2R: it usually means a widened stop, an entry without a stop or a news spike.
Can I calculate an R multiple if I do not use a stop?
Only with a conventional R: the base risk of your plan, the risk you should have taken. It keeps those trades in your statistics, but it says less than a real R. If you trade without a stop often, the fix is not a better-calculated R, it is placing the stop.
What is a good average R multiple?
What matters is not the average R of your winners but the average across all trades, which is your expectancy. A net expectancy of +0.2R over a hundred trades or more is a solid edge; +0.6R over twelve trades is still an anecdote.

Add an initial-risk column to your journal today and fill it in before every entry. If you do not know how many contracts match your R with the stop on your next trade, the position size calculator tells you, with commissions included. After thirty trades logged in R you will have an expectancy that does not depend on the size you happened to trade each week.
