Foreign exchange markets facilitate the trade of one foreign currency for another. Most exchanges are made in bank deposits and involve U.S. dollars. Over a trillion dollars in foreign exchange trades take place every day; foreign exchange dealers handle most transactions.

What most people don't realize is that there is a foreign exchange market - or 'Forex' for short - where you can potentially profit from the movement of these currencies. The best known example is George Soros who made a billion dollars in a day by trading currencies.
