Cognitive Bias
A systematic error in thinking that distorts perception, judgement, and decision-making — markets are full of them.
A cognitive bias is a predictable, systematic deviation from rational thought caused by the brain's need to process information quickly using shortcuts (heuristics). In everyday life many biases are harmless or even helpful. In trading, where decisions carry direct financial consequence, they are expensive.
The most damaging ones for traders: confirmation bias (only seeing what you want to see), anchoring (over-relying on a reference price), recency bias (extrapolating the last few candles), and loss aversion (feeling losses harder than gains). They all interact — a single bad trade can trigger anchoring, loss aversion, and confirmation bias simultaneously.
Awareness is the first step, but awareness alone is not enough. Systematic rules, checklists, and journals are the structural countermeasures that make awareness actionable.
