The short answer
Trading psychology concerns how attention, emotion and decision habits affect execution. Written rules, consistent size and a journal make repeated behaviour easier to observe and review.
- Recognise common decision traps in market practice.
- Reduce impulsive actions with pre-commitment.
- Use a journal to improve process rather than judge identity.
Four predictable traps
FOMO appears when a move feels like a rare chance and the cost of waiting feels unbearable. Loss aversion can make a small loss feel larger than an equal gain feels good. Overconfidence follows a run of wins and can quietly increase size. Revenge trading tries to recover a loss with urgency instead of evidence.
These patterns are not proof that someone lacks discipline. They are predictable effects of uncertain rewards and losses. Naming the trigger makes it easier to add a pause or a limit.
- FOMO: entering because the move is already visible.
- Loss aversion: refusing to accept a planned invalidation.
- Overconfidence: increasing exposure after a streak.
- Revenge: trading to repair an emotional balance sheet.
Pre-commitment is a practical tool
Write the entry condition, invalidation, size and no-trade conditions before the market is moving. Use alerts instead of constant scrolling. Add a daily loss limit or a maximum number of decisions if repeated activity reduces your quality.
A rule is only useful if it is easy to follow. A simple size cap can be more protective than a complex emotional checklist during a fast market.
Journal the decision, not only the result
Record what you knew at the time, why the setup met your rule, how you felt, what you executed and what you learned. A winning trade can be poorly executed and a losing trade can be well executed. Reviewing only profit reinforces luck as if it were skill.
Look for repeated behaviours: late entries, moving stops, adding to losers, trading outside hours or ignoring costs. Choose one behaviour to improve over the next sample.
Turn a feeling into a rule
If a losing example tempts you to widen a stop, write an if-then rule before the next practice session: 'If I want to move a stop farther away, I will record the reason and close the rehearsal instead.'
Review whether the rule was followed over several examples. The goal is to observe a repeatable behaviour, not to diagnose a personality trait from one gain or loss.
A two-minute pause
Before an unplanned entry, write the reason, the invalidation and the cash risk. If any field is missing, wait two minutes and review the plan. The pause is not a prediction; it is friction against an impulse.

Before you move on
How do I stop FOMO?+
You cannot remove the feeling completely. Use a written condition, an alert and a rule that a missed move is preferable to an unplanned risk.
Should I trade to build confidence?+
Confidence is more useful when it comes from following a process over a meaningful sample, not from forcing activity.
What should a trading journal include?+
Date, market, setup, entry, invalidation, size, costs, context, emotions, execution quality and the lesson for the next sample.
