The foreign exchange is the biggest financial market there is. Despite this, many remain unfamiliar with currency trading. Experts attribute this to the monopoly of the currency trading market. Before internet trading was popularized years ago, the foreign exchange was dominated by multinational companies, huge financial institutions, and very, very private hedge funds. Times have changed, however, and the foreign exchange is not for corporations and the very rich anymore. Small investors have started to dabble in currency trading. The most fascinating thing about the foreign exchange is that all members trade upon credit agreements. In essence, transactions in the world's biggest, most liquid market hinge on little more than a handshake.
