The FX market is an inter-bank or inter-dealer network first established in 1971 when many of the world’s major currencies moved towards floating exchange rates. It is considered an over-the-counter (OTC) market, meaning that transactions are not conducted on an exchange like some equity stock markets such as the New York Stock Exchange (NYSE) or the Chicago Options Board Exchange (CBOE) where options and futures are traded. OTC trades exist as agreements made between two parties that agree to trade via telephone or electronic network.

As FX trading has evolved, several locations have emerged as market leaders. Currently, London, England contributes the greatest share of transactions with over 32% of the total trades. Other trading centers—listed in order of volume— are New York, Tokyo, Zurich, Frankfurt, Hong Kong, Paris, and Sydney.

Because these trading centers cover most of the major time zones, FX trading is a true 24-hour market that operates five days a week. For example, as a trader in New York, you have access to the FX market starting Sunday evening when the market opens in Sydney for the start of the trading week. Trading centers around the globe then come online until New York closes at 4:30 PM EST. Of course, by this time, Sydney will have reopened for the next trading day so you can continue to trade around the clock until the New York close on Friday.
