If XAUUSD changes by USD 1, gross P/L changes by about USD 100 for one lot and USD 1 for 0.01 lot, before costs. The account statement converts when account currency differs.
Troy versus ordinary ounce
| Measure | Approximate grams | Use |
|---|---|---|
| Troy ounce | 31.1035 | Precious metals |
| Avoirdupois ounce | 28.3495 | Everyday goods |
| Difference | 2.754 | Do not substitute |
Code versus contract
XAU standardizes the unit. The Exness specification defines lot, margin, commission and settlement. Because the product is a CFD, the code does not confer bullion ownership.
Payment interpretation
A Namibia deposit in NAD or another currency does not change XAUUSD’s USD quote. Track deposit conversion, trading P/L conversion and withdrawal conversion as separate records.
