Forex trading, short for foreign exchange trading, involves the buying and selling of the many currencies of the world. It does not operate via a central exchange site, like traditional stock market trading, and may, thus, fully function a 24-hour basis. When compared to other exchanges, the foreign currency trading market is the largest in the world, even beating the New York Stock Exchange (NYSE) by over a hundredfold, in terms of daily trading volume, most of which are conducted by private entities and individuals.
Because of the absence of a central exchange, foreign currency trading happens between two parties directly. Buyers and sellers communicate and trade via the phone, the Internet or other communications networks worldwide. In addition, trading forex is also speculative, meaning, they are based on expectations on whether a certain currency would rise or fall, depending on current market conditions. It is risky business, but the returns have often proved themselves worth the risk.
