Forward testing
Definition
Running a strategy on live data before committing real capital.
Why it matters
Forward testing captures slippage, spread and your own hesitation, all of which backtests miss.
Example
A strategy that backtested at 1.8 profit factor but forward-tests at 1.05 usually lost the gap to spread, slippage and fills the backtest assumed were free.
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 forward testing stops being something you estimate and becomes something you read.
