Frequently asked questions
What is a good expectancy per trade?
Anything reliably positive after costs is workable; sustained expectancies around 0.2–0.5R per trade are solid for retail strategies. The dollar figure matters less than the R figure, because R scales with whatever account size you trade.
What does profit factor mean?
Profit factor is gross profits divided by gross losses. Above 1.0 the strategy makes money; 1.5–2.0 is generally considered robust; far higher values on small samples usually signal luck rather than skill.
How many trades do I need before these numbers mean anything?
Treat statistics from fewer than 50–100 trades as provisional — small samples swing wildly. Recompute as your journal grows and expect the numbers to drift toward their true values.
