Edge
Definition
A repeatable reason your trades make more than they lose.
Why it matters
An edge is only proven by a sample of executed trades with positive expectancy net of costs, which is exactly what a journal produces.
Example
Positive expectancy over 150+ trades on the same setup, holding up across different weeks and market conditions - not a good month.
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 edge stops being something you estimate and becomes something you read.
