Trading discipline

Definition

Executing your plan the same way whether the last trade won or lost.

Why it matters

Discipline is measurable. Tag every trade as planned or unplanned and compare the two expectancies.

Example

Taking the same size on the trade after a loss as on the trade after a win. The journal proves it: compare average size following winners versus losers.

How to track it in a journal

TradeStack calculates the core performance numbers — win rate, average win and loss, profit factor, expectancy, drawdown and consistency — automatically from imported trades, so trading discipline stops being something you estimate and becomes something you read.
