Trading Psychology: Managing Behaviour Under Uncertainty

The Biases That Appear Most Often

Loss aversion pushes traders to hold losers and cut winners. Confirmation bias filters out contradicting evidence once a position is open. Recency bias overweights the last few outcomes. Overconfidence follows a winning streak almost mechanically. None of these can be removed; they can only be constrained by process.

• Loss aversion: holding losers, cutting winners early
• Confirmation bias: seeking only supporting evidence
• Revenge trading: sizing up after a loss
• Outcome bias: judging a good process by one bad result

Tilt and the Cost of the Next Trade

Tilt is the state in which decisions are driven by the previous result rather than the current setup. Its signature is a position taken outside the written strategy, usually larger than normal. A hard rule — a pause after a defined number of losses, or after a daily loss limit — is the only reliable interruption.

Journaling as Evidence Collection

A journal that records the reason for entry, the planned invalidation and the emotional state at execution converts vague self-assessment into data. Reviewed weekly, it usually reveals that a small number of repeated behaviours account for most losses.

Environment Shapes Behaviour

Interface design influences decisions. One-click execution, prominent leverage sliders and gamified notifications all affect behaviour. When our team documents trading environments — including in the detailed analysis of NV-Group — interface friction is treated as a behavioural variable, not a cosmetic one.
