How to calculate the commission per million nominal currency on our Premiere account

A nominal exchange rate is defined as the number of units of the base currency that can purchase a unit of a given quote currency. As such the nominal amount of a currency pair trade, is the amount of units traded of the base currency.

The commission calculation on our Premiere account is based on the nominal currency amount and is USD 90.0 per million on FX and Metals.
This means that if you buy/sell any currency other than USD, the number of lots you bought/sold in the nominal currency need to be converted to USD in order to calculate the commission.

Example 1:

Buy 1.00 lot GBPUSD at 1.21556
This means you bought 100,000 GBP.
100,000GBP will need to be converted to USD at the GBPUSD spot exchange rate at the time of execution (1.21556): 100,000 x 1.21556 = USD 121,556.00
The commission charged on your account would then be: USD 121,556.00 x 90/1,000,000 = USD 10.94

Example 2:

Sell 1.00 lot USDJPY at 116.127
This means you sold 100,000 USD
The commission charged on your account would then be: USD 100,000 x 90/1,000,000 = USD 9.00
