XAUAUD Lot Size Calculator

XAUAUD is a metal — this calculator uses its own real contract size and point value rather than a one-size-fits-all forex formula, since point value and typical price steps vary a lot between instrument types.

How do I calculate lot size for XAUAUD?

Say a trader has a $10,000 account and decides to risk 1% of it on a XAUAUD long (buy) at 5,885.92, with a stop 883 points away at 5,797.62.

Rounded to a size a broker will actually accept, that's 0.02 lots — a $123.95 loss if the stop is hit.

Using the same 883-point stop, here's how that scales at two common risk levels on a $10,000 account:

• Conservative (1% risk): $100.00 at risk, 0.02 lots
• Balanced (2% risk): $200.00 at risk, 0.03 lots

These are illustrative figures at a fixed example balance and stop — the calculator above uses live prices and your own real inputs. The percentage-risk model itself follows the position-sizing approach popularized by Van Tharp in Trade Your Way to Financial Freedom, among the most widely cited references for treating position sizing as its own risk-management discipline.

What is a standard, mini, and micro lot on XAUAUD?

At XAUAUD's stored contract size (100 units per lot), a "mini" position (0.1 lots) and "micro" position (0.01 lots) scale the point value down by the same factor — $0.70 and $0.07 per point respectively. Useful for sizing a position precisely rather than rounding to a full lot.

When should I adjust my lot size for XAUAUD?

Consider sizing down around high-impact news events or major session overlaps, when volatility and slippage risk increase — a stop that normally holds can be jumped past entirely in a fast move. That risk is higher for this instrument than for a typically calmer major forex pair.

Conclusion

This math only holds if 100 units per lot and $7.02 per point are actually your own broker's real numbers for XAUAUD — every broker can quote contract specifications slightly differently. Always confirm your own platform's XAUAUD specification (right-click the symbol in Market Watch, then Specification) before trusting a suggested lot size for a real trade.
