The International Foreign Exchange Market FOREX enables its participants to exchange one currency for another one. Exchange rates determine the relative amount of each currency in the exchange process.
Today the FOREX market has a turnover of more than three trillion dollars a day, which is by order of magnitude greater than turnovers of other world markets. It operates through a global network of banks, corporations and individuals trading one currency for another. The lack of a physical exchange enables the Forex market to operate on a 24-hour basis, spanning from one zone to another in all the major financial centers.
Now the doors of Forex are opened for retail investors due to Internet-trading, which gives them all necessary opportunities for effective investing.
