For XAUUSD scalping, risk 0.25% to 0.5% of equity per trade with a $3 to $5 stop, cap trades at around six per session, and apply a hard daily loss limit near 1.5% of equity.
A standard XAUUSD lot is 100 ounces, so of movement equals 00 per lot and 0 per 0.10 lot; a $4 stop on 0.10 lots risks $40 before spread and commission.
Expectancy must be measured after costs across at least 100 logged scalps before the strategy is treated as profitable.
