Trading Discipline

Trading discipline is the consistent execution of predefined research, sizing, order, exit, and review rules despite emotional pressure or recent outcomes.

Discipline is better treated as a system design problem than as constant willpower, using checklists, limits, alerts, and pauses to make intended actions easier. It includes declining trades that do not qualify and recording rule breaches without rewriting the plan afterward. Consistency cannot make an unprofitable method profitable, so the process must still be tested and revised from evidence over time.
