FX Forex is a worldwide decentralized over-the-counter financial market for the trading of currencies. Financial centres around the world function as anchors of trading between a wide range of different types of buyers and sellers around the clock, with the exception of weekends. The foreign exchange market determines the relative values of different currencies.

The primary purpose of FX Forex is to assist international trade and investment, by allowing businesses to convert one currency to another currency.

The FX Forex market is different to other traded markets because of its huge trading volume, leading to high liquidity, multi-geographical locations, continuous operation: 24 hours a day except weekends, the variety of factors that affect exchange rates, the low margins of relative profit compared with other markets of fixed income and the use of leverage to enhance profit margins with respect to account size.
