The Disposition Effect in Your Own Data
The disposition effect is the tendency to sell winners too early and hold losers too long. It appears in professional and retail investors alike, and in forex it shows up as a distinctive pattern in the numbers.
To test whether it affects you, compute three things from your journal. First, average win in R compared with average loss in R. If your wins average 0.8R and your losses average 1.2R, you are cutting winners and letting losers run beyond the plan. Second, the share of trades where you exited before the target. Third, the share of losing trades where you moved the stop or removed it.
Some version of this appears in most traders' records. The reason is emotional: realizing a gain feels good, and realizing a loss feels painful, so people act to lock in the good feeling and avoid the bad.
Countermeasures work best when they are mechanical. Place stops and targets as orders when you enter, so exits happen without a decision. Limit changes to stops to one direction only, toward reducing risk. Predefine partial profit rules. Review weekly with the numbers in front of you.
Reducing position size can also help, because lower stakes weaken the emotional pull.
Track your average win and loss in R weekly, and watch the ratio change as discipline improves.
Practical step: calculate your average win in R and average loss in R, and write the difference as a target for improvement.
