Quoting Foreign Currency

Quoting Foreign Currency

Currencies are always quoted in pairs. Each pair of currencies thus constitutes an individual product and is traditionally noted XXX/YYY, where YYY is the ISO 4217 international three-letter code of the currency into which the price of one unit of XXX currency is expressed.

The first currency in the quotes act as the 'base currency'.

For example USD/JPY, EUR/GBP, and GBP/AUD, in such cases, USD, Euro Dollar, and Britain Pound are acting as the base currency. Base currency in a Forex quote will always has a value of 1. USD/JPY indicates how much Japanese Yens you can buy with 1 United States Dollar; similarly EUR/GBP indicates the exchange rate of Great Britain Pound with 1 Euro Dollar.
