Definition

Compare the size of your average winner and loser.

Formula. Average net winning trade ÷ average absolute net losing trade. This is realized payoff, not the planned reward / risk at entry. Requires both winners and losers.

Where the planned ratio goes

BehaviourEffect on realized ratio
Taking profit before targetAverage win falls; ratio drops
Moving a stop away from entryAverage loss rises; ratio drops
Scaling out early on winners onlyAverage win falls while losses stay full size
Cutting losers early and holding winnersRatio rises — the intended direction

How it goes wrong

Confusing it with the planned ratio
This figure is realized payoff, computed from outcomes. It is not the reward-to-risk you set at entry, and the difference between them is the point.
Reading it without winners and losers
The ratio requires at least one of each. Orderblock reports it as unavailable rather than producing a misleading value from an incomplete sample.

Questions

My planned ratio is 3:1 but realized is 1.1:1. What now?

Compare average loss against your recorded risk. If losses exceed 1R the problem is stop discipline; if they sit at 1R but winners fall short of target, the problem is exiting early. These need opposite fixes, which is why the two numbers have to be read together.
