Profit factor
Profit factor is the sum of all winning trades divided by the absolute sum of all losing trades. Above 1 the strategy makes money; below 1 it loses. Run this calculation now: how to measure your own performance
How to compute it and what to expect
If winners total 12,000 and losers total 8,000, profit factor is 1.5: every unit lost returned one and a half. Values between 1.3 and 1.8 are typical of real, sustainable strategies; above 2.5 on a small sample is usually luck or a bad regime not yet lived through.
Unlike win rate, profit factor already embeds the size of results. A strategy winning 35% of the time can show 2.0, and one winning 75% can show 0.8.
The traps
A single huge trade distorts the metric: recompute without the best result and see whether it survives. A sample below 50 trades supports no conclusion, and comparing factors across periods of very different volatility compares different things.
TCC computes the factor per account, per period and per instrument, always with the trade count next to it — because the number without the sample is decoration.
