Foreign exchange or Forex is the simultaneous buying of one currency and selling of another. Currencies are traded through a broker or dealer and are executed in currency pairs. For example: the Euro and the US Dollar (EUR/USD) or the British Pound and the Japanese Yen (GBP/JPY). The Foreign Exchange Market (Forex) is the largest financial market in the world, with a daily volume of over $4 trillion. This is more than three times the total amount of the stocks and futures markets combined. Unlike other financial markets, the Forex spot market has neither a physical location nor a central exchange. It operates through an electronic network of banks, corporations, and individuals trading one currency for another. The lack of a physical exchange enables the Forex market to operate on a 24-hour basis, spanning from one time zone to another across the major financial centers. This fact - that there is no centralized exchange - is important to keep in mind as it permeates all aspects of the Forex experience.
