At about 14:00 GMT, after dinner, European dealers resume their work. That is exactly the time when American traders start their work. When they join the European traders, the market experience a big flow of funds. But the volumes and forces of American and European financial institutions are about the same, so currency fluctuations usually show small vibrations of a purely European session. But the opening of the New York Stock Exchange is extremely interesting for traders, because the American market determines the further movement of the courses. In the evening, after 17:00 GMT when the European stock exchanges are closed and U.S. banks remain alone in the "thin" market, this is the time when strong movements take place associated with the American dollar. Changes in rates can reach several percent and held for 400-500 points. This is a the time when the market experienced the biggest movements and many traders take their chance to make profits.
