Psychology: the biases that cost money
You will learn to
- Name the common biases
- Recognise them in your own trades
- Concrete counter-measures
Biases every trader has
| Bias | In trading | Counter |
|---|---|---|
| Loss aversion | Holding losers, cutting winners early | Stops and targets set before entry; no manual moves |
| FOMO | Chasing a candle that already moved | Only enter at your planned location |
| Recency | Three losses → "the strategy is broken" | Judge over 30–50 trades, not a week |
| Overconfidence | Raising size after a streak | Fixed risk %; guardrail cap |
| Confirmation bias | Seeing only the signals that agree with your position | Write the invalidation before entry |
| Hindsight bias | "It was obvious" (often a repainted chart) | Bar Replay; as-it-happened patterns |
State matters
Tired, angry, or needing the money — not the time to trade. The last checklist line ("I am calm") is there for a reason. Many traders set a daily routine: plan before the session, trade the plan, review after — and no trading outside it.
