How it works

Lots = amount at risk ÷ (stop loss × pip value per lot). For gold, 1 pip = $0.10 move = $10 per standard lot (100 oz). For US30, $1 per point per lot. JPY pairs use the live USDJPY rate.

Worked example

Account SAR 40,000, risk 1% (SAR 400 ≈ $107). Gold stop loss 50 pips → $107 ÷ (50 × $10) = 0.21 lots.
