Forex is a term that stands for Foreign Exchange. It is sometimes just FX, too. These terms all describe the process of trading the currencies in the world. Unlike the stock market, in the Forex markets, you do not trade ownership in a business. Rather, you are trading the value of money, based on the ups and downs of the currencies of the market. It sounds interesting because it is.
The simple sense of Forex is simultaneous purchase and sale of the currency or the exchange of one country's currency for the one of another country. The world currencies do not have a fixed exchange rate and are always fluctuating, since each are traded in the currency pairs like Euro/Dollar, Dollar/Yen and others. 85% of daily trades are taken by major currencies trading.
