R-multiples and expectancy

You will learn to
  • Measure trades in R
  • Calculate expectancy
  • Include fees

Think in R

R is the amount you risked. A loss at the stop is −1R; a win at a target twice as far is +2R. R lets you compare trades of any size and any market.

Expectancy

expectancy = win% × average win (R) − loss% × average loss (R)

Win rateAvg winExpectancy
40%2R+0.20R
70%0.5R+0.05R
55%0.7R−0.07R
30%3R+0.20R

Win rate alone tells you nothing. Many "80% win rate" systems lose money because the 20% of losses are large.

Fees are part of R

On Binance futures a round trip costs about 0.10–0.12% of the position (taker 0.05% per side plus slippage). With a 0.4% stop that is a quarter of an R gone on every trade before price moves — which is why tight stops on low timeframes so often fail after fees.

1. 45% win rate, winners +2R, losers −1R. Expectancy before fees?
  1. +0.35R ✓
  2. −0.10R
  3. +0.90R
0.45 × 2 − 0.55 × 1 = 0.35R.
2. Round-trip costs 0.12% and your stop is 0.4% away. Fees per trade in R ≈
  1. 0.03R
  2. 0.3R ✓
  3. 3R
0.12 ÷ 0.4 = 0.3R.
