Process vs. outcome
A profitable trade isn't automatically a good decision. A losing trade isn't automatically a mistake.

Two different questions
After a trade closes, it's natural to ask "did it make money?" That question is about the outcome. A second question is about the process: "given what I knew when I entered, was this a decision I'd want to repeat?"
The two can disagree. Price movement involves uncertainty that no plan removes. A sound decision can be followed by a loss, and a careless one can be followed by a gain.
Why judging by results alone misleads
- It can reward luck. If a trade that ignored your rules happened to work, treating it as proof makes the habit more likely to repeat.
- It can punish good decisions. If a well-planned trade loses within its risk limit, abandoning the plan means discarding something that may be working as designed.
- Small samples are noisy. A handful of trades is rarely enough to tell skill from chance, so a short run of wins or losses says little about the quality of the process.
What to evaluate instead
Process questions can be answered from your own records, regardless of the result:
- Did the trade meet the criteria in my written plan?
- Was my stop (the point where the idea is wrong) defined before I entered?
- Was the position size set from my risk limit?
- Did I manage the trade according to the plan, or react on impulse?
- If I took a loss, was it within the amount I had decided to risk?
A simple habit: after each trade, record the outcome and score the process separately, for example "followed plan: yes / partly / no". Over weeks, the process record is often more informative than the profit and loss column.
What this doesn't mean
Focusing on process doesn't mean outcomes don't matter, and it doesn't guarantee good results. A process can be sound and still be unprofitable if its underlying idea doesn't hold up. Reviewing process is how you find that out with evidence rather than by feel.
