Forex, also known as foreign exchange, FX or currency trading, is a decentralized global market where all the world's currencies trade. The forex market is the largest, most liquid market in the world with an average daily trading volume exceeding $5 trillion. All the world's combined stock markets don't even come close to this. But what does that mean to you? Take a closer look at forex trading and you may find some exciting trading opportunities unavailable with other investments.
One unique aspect of this international market is that there is no central marketplace for foreign exchange. Rather, currency trading is conducted electronically over the counter (OTC), which means that all transactions occur via computer networks among traders around the world, rather than on one centralized exchange. The market is open 24 hours a day, five and a half days a week, and currencies are traded worldwide in the major financial centers of Frankfurt, Hong Kong, London, New York, Paris, Singapore, Sydney, Tokyo, and Zurich—across almost every time zone. This means that when the U.S. trading day ends, the forex market begins anew in Tokyo and Hong Kong. As such, the forex market can be extremely active anytime, with price quotes changing constantly.
