Forex which is an acronym for foreign exchange is a market that has been in existence since the 1970′s. Today forex trading has become so successful that for many it has become a lucrative career move. In a nutshell forex trading is simply the buying of one currency using another currency or selling one currency to obtain another. The exchange rate between the currencies will determine how much you will have to sell one currency to buy another and usually the consistency of a rate will be determined based on how much confidence the world has on a currency which will in turn depend on factors such as their economic and political stability, consumer sentiment etc.
