Definition
Fear and greed are shorthand for emotional pressures that can push trading decisions away from a predefined evidence and risk process.
In market context
Fear can prompt panic exits, hesitation, or excessive caution, while greed can encourage chasing, oversizing, and refusal to take a planned profit. The labels do not diagnose a person or reliably forecast a market, and the same action can be rational under different facts. Written rules, cooling-off periods, and exposure limits help separate emotional intensity from the evidence required for a decision.
