The Foreign Exchange market, referred to as "Forex" or "FX", is the market where currencies are traded. Currencies are traded in pairs, buying one currency whilst selling the other (for example British pound and US dollar (GBP/USD)).

The Forex market is currently the largest and most liquid market in the world with an average traded value that exceeds $3.2 trillion per day.

Due to the fact that there is no physical marketplace for the currency exchange market, it is considered an Over the Counter Market (OTC). Trades are conducted through telephone, fax, or electronic network (computers with access to internet), instead of a physical trade floor.

The Forex market is open 24 hours a day, five days a week. Currencies are traded worldwide among the major financial centres of London, New York, Tokyo, Zürich, Frankfurt, Hong Kong, Singapore, Paris and Sydney - covering all time zones.
