Gold Lot Size Calculator (XAUUSD)

About XAUUSD Trading

Calculating lot size for XAUUSD requires special attention because gold's pip value ($1.00 per pip per standard lot) is different from standard forex pairs ($10.00). Using a standard forex calculator will give you 10x the correct lot size — a potentially account-destroying mistake.
