The foreign exchange market (currency, forex, or FX) trades currencies. It lets banks and other institutions easily buy and sell currencies.
The purpose of the foreign exchange market is to help international trade and investment. A foreign exchange market helps businesses convert one currency to another.
In a typical foreign exchange transaction a party purchases a quantity of one currency by paying a quantity of another currency. The modern foreign exchange market started forming during the 1970s when countries gradually switched to floating exchange rates from the previous exchange rate regime, which remained fixed as per the Bretton Woods system.
The foreign exchange market is unique because of
* its trading volumes,
* the extreme liquidity of the market,
* its geographical dispersion,
* its long trading hours: 24 hours a day except on weekends
* the variety of factors that affect exchange rates.
* the low margins of profit compared with other markets of fixed income (but profits can be high due to very large trading volumes)
* the use of leverage
