Currency Pairs

Currency Pairs: Each currency is recognized by a three letter code. For example EUR (is the EURO and refers to the European currency), USD (is the United States Dollar). The worlds leading currencies (often referred to as the majors) are the EUR, USD, JPY (Japanese Yen), GBP (the British Pound or Sterling), CHF (the Swiss franc), AUD (the Australian Dollar) and the CAD (the Canadian Dollar).


Currencies are traded in pairs and are displayed as such. There is always the three letter currency code a slash and another three letter currency code. The first currency displayed refers to the "base", "leading" or "primary currency"; the second currency refers to the "secondary currency".

For instance when looking at the EUR/USD the EUR is the leading currency and the USD is the secondary currency. The "currency pair" or "currency cross" is then followed by a number; this is typically a five digit number with a decimal point after the first, for instance 1.2660.

The number represents the ratio of one currency against the other, and can be read as "the amount of the secondary currency needed in order to have one unit of the major currency". In the example just given, EUR/USD 1.2660, one would require 1 Dollar and 26.6 cents to exchange for 1 Euro.
