Unlike other financial markets, the foreign exchange market has no physical location and no central exchange. 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. In the event that funds in your account fall below margin requirements, most forex platforms will automatically close one or more open positions. This prevents your account from ever falling below the available equity even in a highly volatile, fast moving market.
