The speed, volatility, and enormous size of the Forex market are unlike anything else in the financial world. The Forex market behaves differently from other markets. Any currency can become very expensive or very cheap in relation to any or all other currencies in a matter of days, hours, or sometimes, in minutes. The unpredictable nature of currencies is what attracts an investor to trade and invest in this market. Beware: the Forex market cannot be controlled - no single event, individual, or factor rules it. However, just like any other speculative business, increased risk entails chances for a higher profits as well as higher losses.
