The foreign exchange (Forex) market is the mechanism, which facilitates the purchase and the sale of foreign currencies. The Forex is a financial market where the participants exchange one monetary unit for another currency. The market operates continuously, 24 hours a day, because a financial center is always open somewhere in the world. The interconnection of the markets makes continuous trading possible (Carrada-Bravo, 2003).
The foreign exchange market is generally divided into five basic currency markets based on pricing procedures ruling the exchange, the time to maturity, the degree of freedom available, the convertibility of currencies, and how the currencies are quoted (Carrada-Bravo, 2003).
In addition, the foreign exchange market is one of the most traded and liquid instruments in the financial world, and serves as a barometer of broader financial market conditions and risk appetite.
