What is XAUUSD?

XAUUSD is gold quoted in US dollars per troy ounce.

XAUUSD point value and contract size

The preset contract is 100 troy ounces per 1.00 lot with $1 per point, so one point is a 0.01 move in price and a full 1.00 move in price is worth $100 on 1.00 lot, $10 on 0.10 lot and $1 on 0.01 lot.

How to calculate XAUUSD lot size

The calculator uses one formula on every market: lots = risk money ÷ (stop in points × value of 1.00 lot per point).

Example: a $10,000 account risking 1% ($100) with a 300 point stop on XAUUSD: $100 ÷ (300 × $1) = 0.3333 lots, which MT4 rounds down to 0.33.

Double the stop and the lot size halves, with the same $100 at risk. That is the whole point of sizing from the stop instead of picking a lot size first.

How to use the XAUUSD lot size calculator

  1. Enter your account size and pick your account currency. Live FX rates convert the result if your account is in another currency.
  2. Set the percent of the account you accept to lose on this trade (1% is a common default) and your stop loss in points, measured from entry to stop on the XAUUSD chart.
  3. Check Tick value in MT4 Market Watch, Specification for XAUUSD. If it differs from the preset, type it in, then read Lots to open and round down to your broker's lot step.

Common XAUUSD position sizing mistakes

  • Copying another broker's lot specs. XAUUSD contract size and tick value vary by broker, so a lot size from a forum post can be far off on your account.
  • Confusing points with price. On XAUUSD one point is 0.01 of price, not 1.00.
  • Picking the lot size first and placing the stop where it fits the lot. Place the stop where the trade idea is wrong, then size.
  • Forgetting spread and slippage. The stop can be hit before price reaches your level, so leave a margin or risk slightly less.

Educational content, not investment advice. Trading leveraged products such as CFDs and forex carries a high risk of losing money.
