Forex or the foreign exchange market is a decentralised system for foreign currency trading and exchange. Foreign exchange is the process of changing one country’s currency into another country’s currency for trading, commerce, or tourism. The rise to the foreign exchange services and trading was due to the varying values of individual currencies. In the world trade market Forex is regarded as the largest and most liquid asset market. National currencies have an exchange rate fixed in pairs, e.g. USD/JPY. Commercial and investment banks carry out most of the trading process on behalf of their clients.
Currency trading is completely conducted electronically over computer networks between institutions, banks, brokers, and individual traders (mostly trading through brokers or banks) around the globe, that is known as over-the-counter (OTC). The market is open 24 hours a day and five trading days a week. Currencies are traded in the major financial centres of London(U.K), New York(U.S), Tokyo(Japan), Zurich(Switzerland), Frankfurt(Germany), Hong Kong(China), Singapore, Paris(France) and Sydney(Australia)—across almost every time zone. This means that when the trading day ends in the U.S., it begins in Singapore and Hong Kong. The forex market is almost active the entire day, with price quotes rapidly changing.
