Fear of Missing Out (FOMO)
The urge to chase price after a strong move has already begun. FOMO entries typically occur at the worst possible levels — near exhaustion points where reversal probability is highest.
Countermeasure: Strict adherence to predefined setups. If the entry criteria are no longer met, the trade simply does not exist.
Revenge Trading
Attempting to immediately recover losses by increasing size or forcing new trades. This emotional response turns a small loss into a catastrophic one.
Countermeasure: Enforced daily loss limits and mandatory breaks after a losing trade or session.
Overconfidence After Wins
A string of winning trades creates the illusion of skill rather than probability. This leads to rule-breaking, larger sizing, and eventual large drawdowns.
Countermeasure: Treat every trade independently. Position size and rules remain constant regardless of recent performance.
Loss Aversion & Hope
The tendency to hold losing positions far longer than planned, hoping for a return to breakeven. Losses are psychologically twice as painful as equivalent gains are pleasurable.
Countermeasure: Hard, pre-placed stop-losses and complete removal of discretion once a trade is live.
Recency Bias
Overweighting recent market behavior while ignoring longer-term probabilities. A few ranging days can feel like the “new normal,” causing abandonment of trend-following rules.
Countermeasure: Rely on objective backtested data and regime filters rather than subjective market feel.
Ego & Narrative Attachment
Becoming emotionally invested in being “right” about a market direction. Traders defend predictions instead of following price action.
Countermeasure: Focus exclusively on process execution. The market is never wrong — only the trader’s response can be.
