American dollar (USD)
This is not only the national currency of the USA, but also the basic currency for all calculations and different operations on the Forex market. If you see a currency pair in front of you that contains the symbol of the dollar — USD, know that it's one of the major currency pairs (for example, EUR / USD - Euro / dollar). If there is no dollar present in the currency pair, before you is a "Cross-rate" (see). However, even in such pairs, calculations can be made on the basis of the USD. In trader jargon, the USA dollar is referred to as “Bucks”.
