is a perfect market. It is also the biggest
liquid financial market. According to various assessments,
money masses in the market constitute from 1 to
1.5 trillion US dollars a day. (It is impossible to determine
an absolutely exact number because trading is not centralized
on an exchange.) Transactions are conducted all
over the world via telecommunications 24 hours a day from
00:00 GMT on Monday to 10:00 pm GMT on Friday.
Practically in every time zone (that is, in Frankfurt-on-Main,
London, New York, Tokyo, Hong Kong, etc.)
there are dealers who will quote currencies.
