Profit factor explained
Profit factor equals gross profit divided by gross loss. Above 1.0 is profitable, 1.5 is solid, 2.0+ is excellent. It measures how many dollars you make for every dollar you lose.
The formula
Profit Factor = Sum of Winning Trades / Absolute Sum of Losing Trades. If your winners total $8,000 and losers total $4,000, profit factor is 2.0.
PF = Gross Profit / Gross Loss
How to read it
PF < 1.0 = losing strategy. PF 1.0-1.5 = marginal. PF 1.5-2.0 = solid, common for discretionary day traders. PF > 2.0 = excellent, often systematic or short-timeframe scalping.
Profit factor vs win rate
Two traders can have the same win rate but very different profit factors. Profit factor rewards letting winners run and cutting losers small, which is why it is a better single-number health check than win rate alone.
How to improve it
Cut the biggest losers first. Removing your worst 5% of trades typically raises profit factor more than raising win rate does. A journal with per-day P&L makes those outliers easy to spot.
Frequently asked
What is a good profit factor for day trading?
1.5 to 2.0 is the realistic sweet spot for discretionary day traders after fees.

Yes, on small samples. A single outsized winner can inflate PF. Look at PF alongside expectancy and drawdown.
