One R is what you risked. Scoring trades in R is how you compare a gold trade with a EUR/USD trade, a big account with a small one, and this month with last.
R is a trade's result divided by the amount it risked: (exit minus entry) divided by (entry minus stop), sign-flipped for shorts. A trade that made twice its risk is +2R and one that hit the stop is -1R. Score against the stop you set at entry, not one you moved, or the number flatters you.

R = result ÷ original risk. Score against the stop you set at entry, not one you moved later, or the number flatters you. Costs are not included here — the profit calculator nets them off.
R = (exit − entry) ÷ (entry − stop), sign-adjusted for shorts. A trade that made twice what it risked is +2R; one that hit the stop is −1R; one closed early for half the risk is +0.5R.
The calculator takes a single trade, or paste a list and it scores the whole set - total R, average R, win rate and the best and worst trade. That is a rough expectancy reading in ten seconds.

A trade's result divided by the amount it risked. +2R means it made twice the risk; -1R means it lost exactly what was planned.
(Exit minus entry) divided by (entry minus stop), with the sign flipped for shorts. The calculator does single trades or a pasted list.
The original. Scoring against a moved stop hides the cost of moving it.
Any reliably positive average after costs, over a large enough sample. The size matters less than whether the sample is honest.
