Currency is the ultimate commodity
A foreign currency trade takes place every time a company or government buys or sells products or services in a foreign country; one currency is exchanged for another. A large number of individuals and organizations also do currency trading for speculative purposes. So, it is no surprise that the foreign currency exchange market, also known as “FOREX” or “FX” market, is the largest financial market in the world.
For day traders and swing traders, the currency market provides an alternative to stock market and futures trading. A trader only has a few major currencies to trade (the Dollar, Yen, British Pound, Swiss Franc, and the Euro are the most popular), whereas he is faced with tens of thousands of stocks to choose from.
