The Foreign Exchange market, also referred to as the "Forex" is the biggest and largest financial market in the world. It has a daily average turnover of US$1.9 trillion- just imagine that amount of money! Don't you want to join this trillion-dollar industry?
Forex is the simultaneous buying of one currency and selling of another. Currencies are traded in pairs, for example Euro/US Dollar (EUR/USD) or US Dollar/Japanese Yen (USD/JPY). So basically, Forex is trading.
There are two reasons to buy and sell currencies. About 5% of daily turnover is from companies and governments that buy or sell products and services in a foreign country or must convert profits made in foreign currencies into their domestic currency.
