Why Do I Cut Winners Early and Hold Losers?

Most traders recognize the pattern. A trade goes your way and you close it quickly, relieved to have a gain. A trade goes against you and you hold on, because closing it would turn a paper loss into a real one. The winners are short and tidy, the losers are long and uncomfortable, and over a month the account shows the difference.

It feels like prudence, but it works against you twice. Cutting winners early caps the size of your wins. Holding losers beyond your stop lets the size of your losses grow. The result is an average loss larger than the average win, which means you need an unusually high win rate just to stay level. Why losses end up bigger than wins shows the arithmetic.

The tendency has a name, the disposition effect, and it is well documented. Knowing the name does not make it go away, though. What helps is measuring it in your own account, so you know whether it is a small habit or the main thing costing you. The loss aversion article explains the psychology and lists the sources.

Your trade history holds the answer, because every trade has an open time and a close time. The analyzer below compares how long you hold your winners with how long you hold your losers, and reports it when the gap is large enough to matter.
