Introduction to Forex

The Foreign Exchange market, also referred to as the "FOREX" or "Forex" or "Retail forex" or "FX" or "Spot FX" or just "Spot" is where currency trading takes place. It is where banks and other official institutions facilitate the buying and selling of foreign currencies. FX transactions typically involve one party purchasing a quantity of one currency in exchange for paying a quantity of another. The foreign exchange market is the largest financial market in the world, with a volume of over $4 trillion a day. If you compare that to the $25 billion a day volume that the New York Stock Exchange trades, you can easily see how enormous the Foreign Exchange really is. It actually equates to more than three times the total amount of the stocks and futures markets combined. . Currencies are traded through a broker or dealer, and are traded in pairs; for example the euro and the US dollar (EUR/USD) or the British pound and the Japanese Yen (GBP/JPY).
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 between 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 London, New York, Tokyo, Zurich, Frankfurt, Hong Kong, Singapore, Paris and Sydney - across almost every time zone. This means that when the trading day in the U.S. ends, the forex market begins anew in Tokyo and Hong Kong. As such, the forex market can be extremely active any time of the day, with price quotes changing constantly.
