Foreign exchange markets facilitate the trade of one foreign currency for another. Most exchanges are made in bank deposits and involve U.S. dollars. Over a trillion dollars in foreign exchange trades take place every day; foreign exchange dealers handle most transactions.
The foreign exchange (forex or FX) currency market is not traded on a regulated exchange like stocks and commodities. Rather, the market consists of a network of financial institutions and retail trading brokers which each have their own individual hours of operation.
