Commonly asked Profit Factor questions
What is profit factor?
Gross profit divided by gross loss (losses as a positive number). Above 1 means aggregate wins exceed aggregate losses before net profit.
Why does it show infinity?
If gross loss is zero but gross profit is positive, the ratio is undefined in practice—often shown as infinity in toy examples.
Profit factor vs win rate?
Win rate counts trades; profit factor compares dollars—two systems can have the same win rate but very different profit factors.
Does profit factor show drawdowns?
No—it summarizes totals over the window, not the path; use equity curves for drawdown analysis.
Should costs be in gross P&L?
Yes for realism—commissions and fees usually belong in the gross buckets you track.
What time period should I use?
Match your strategy review cycle; rolling windows help spot regime changes versus one all-time number.
