What is Profit Factor?
Profit factor is the mathematical ratio of gross trading profits divided by gross trading losses over a given trading sample. A profit factor above 1.0 confirms overall profitability, while institutional prop trading benchmarks require a sustainable profit factor between 1.6 and 2.5.
Mathematical Calculation
Total dollar amount of all winning trades divided by the absolute dollar sum of all losing trades. A profit factor of 2.00 indicates you earn $2.00 in gross profit for every $1.00 lost.

Profit Factor Across a 50-Trade Sample
Total Trades: 50 executions on NQ futures.
Gross Profits: 28 winning trades generating +$14,000.
Gross Losses: 22 losing trades accumulating -$7,000.
Calculation: $14,000 ÷ $7,000 = Profit Factor of 2.00.
Net Realized Gain: +$7,000 (before broker fee drag).
