Gold requires larger samples than lower-volatility instruments because its outcome distribution is wide: 100 XAUUSD trades gives a first read, 250 a usable expectancy estimate, and under thirty is noise.
Condition coverage matters as much as trade count — a sample should span trending and ranging gold plus at least one CPI, NFP and FOMC before any conclusion is drawn.
Sample size is the least glamorous and most decisive question in gold testing. On an instrument with 20-plus-dollar daily ranges, small samples produce beautiful curves that mean nothing at all.
