USD/AUD FAQ

USD/AUD lot size FAQs

How do I calculate the lot size for USD/AUD?

Enter your account balance and currency, choose USD/AUD, set your risk per trade as a percentage (for example 1%), and enter your stop loss. The calculator multiplies balance by risk% to get the money at risk, then divides that by your stop distance times the USD/AUD pip value per lot. When your account currency differs from Australian Dollar (AUD), the pip value is converted with live exchange rates before the lot size is worked out.

What is one pip of USD/AUD worth?

One pip of USD/AUD moves the value of a 1.00 lot by 10.00 AUD. This is the contract size (100,000 USD) multiplied by the pip size (0.0001). Because USD/AUD is quoted in Australian Dollar, that pip value is in AUD; the calculator converts it to your account currency automatically.

What is 1 lot of USD/AUD?

A standard 1.00 lot of USD/AUD represents 100,000 USD. A 0.10 lot is a tenth of that and a 0.01 lot (a micro lot) is a hundredth. Brokers can define contract sizes differently, so confirm the specification in your MT4/MT5 symbol details before sizing a live trade.

Why does the calculator show an exact size and a broker-ready size?

The exact size is the pure mathematical answer, for example 0.0167 lots. Most brokers only accept volumes on a grid set by a minimum lot and lot step (often 0.01), so the broker-ready size is the largest valid volume at or below the exact size. It never rounds up, so your actual risk on USD/AUD never exceeds the risk you set.

Does the USD/AUD lot size depend on my account currency?

Yes. USD/AUD is quoted in Australian Dollar (AUD), so unless your account is in AUD the calculator converts the pip value to your account currency with live exchange rates. Two accounts in different currencies can therefore get slightly different lot sizes for the same trade.
