Unlike other financial markets Forex has no physical location, like stock exchanges, for example. It operates through the electronic network of banks, computer terminals or via telephone. The lack of physical exchange enables Forex to operate on a 24-hour basis, spanning from one time zone to another across the major financial centres (Sydney, Tokyo, Hong Kong, Frankfurt, London, New York etc). In every financial centre there are many dealers, who buy and sell currencies 24 hours a day during the whole business week. Trading begins in the Far East, New Zealand (Wellington), then Sydney, Tokyo, Hong Kong, Singapore, Moscow, Frankfurt-on-Maine, London and ends in New York and Los Angeles.
