Exchange rate

Currencies are traded in pairs and exchanged one against the other when traded, so the rate at which they are exchanged is called the exchange rate. The majority of the currencies are traded against the US dollar (USD). The four next-most traded currencies are the euro (EUR), the Japanese yen (JPY), the British pound sterling (GBP) and the Swiss franc (CHF). These five currencies make up the majority of the market and are called the major currencies or "the majors". Some sources also include the Australian dollar (AUD) within the group of major currencies.
