What is Missed R
MFE minus the actual result: how many R of the trade's peak the exit did not capture. A large miss across the sample is a question for your exit rules.
How it works
Example
MFE +2.6R, closed at +1R — 1.6R missed. If that happens in 30 trades out of 40, the target needs another look.
Common mistake
Treating missed R as a mistake on every trade: exiting at the exact peak is impossible.
