The foreign exchange market or forex market as it is often called is the market in which currencies are traded. Currency Trading is the world’s largest market consisting of almost trillion in daily volume and as investors learn more and become more interested, the market continues to rapidly grow. Not only is the forex market the largest market in the world, but it is also the most liquid, differentiating it from the other markets. In addition, there is no central marketplace for the exchange of currency, but instead the trading is conducted over-the-counter. Unlike the stock market, this decentralization of the market allows traders to choose from a number of different dealers to make trades with and allows for comparison of prices. Typically, the larger a dealer is the better access they have to pricing at the largest banks in the world, and are able to pass that on to their clients. The spot currency market is open twenty-four hours a day, five days a week, with currencies being traded around the world in all of the major financial centers.
