The global Forex market is vast. It 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 primary purpose of the foreign exchange market is to assist international trade and investment, by allowing businesses to convert one currency to another currency.

The global Forex market is different to other traded markets. This is because of its huge trading volume, high liquidity, multi-geographical locations and continuous operation: 24 hours a day except weekends. This global Forex market is popular due to 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.
