Read the ± Before the Number
E(R) needs an interval
Expectancy per trade has a huge per-sample spread (SD ≈ 1.4R). So a headline E(R) means nothing without its sample size. Set a measured E(R) and how many trades it came from:
Measured E(R)+0.30R
Sample size (n)50
At n=50 the interval is about ±0.39R — so +0.32R and 0.00R are the same measurement. Real thresholds need n≈400+.
