Trading Psychology

Loss Aversion and Why It Sabotages Your Trading

Losses feel twice as painful as equivalent gains — this asymmetry causes irrational trading behaviour.

Key rules

1. Humans feel losses 2x more intensely than equivalent gains
2. This causes holding losers and cutting winners — the worst pattern
3. Use automated stop-losses to remove emotion from loss exits
4. Set take-profit targets before entry and honour them
5. Review your average win vs. average loss in your journal

Psychologists Kahneman and Tversky found that losses hurt roughly twice as much as equivalent gains feel good. In trading, this causes holding losing positions (avoiding the pain of realising the loss) while cutting winners short.

This is the opposite of what a positive-expectancy system requires. The fix is mechanically rule-based exits — let your stop-loss close losers automatically.
