USD/GBP FAQ

USD/GBP lot size FAQs

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

Enter your account balance and currency, choose USD/GBP, 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/GBP pip value per lot. When your account currency differs from British Pound (GBP), the pip value is converted with live exchange rates before the lot size is worked out.

What is one pip of USD/GBP worth?

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

What is 1 lot of USD/GBP?

A standard 1.00 lot of USD/GBP 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/GBP never exceeds the risk you set.

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

Yes. USD/GBP is quoted in British Pound (GBP), so unless your account is in GBP 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.
