The American session

At 13:00 GMT, the New York session opens at the same time as the London session. With the combined participants from both the London and New York sessions, volume and volatility are generally increased.

 

 

At 17:00 GMT, the London session draws to a close and then New York trades by itself until the Asian session opens again.

At that time, only New York is open and although the trading volume is still higher than during the Asian session, the volume is likely to decrease with the exit of the European traders.

During the American session there are no particular currency pairs that should or should not be traded.
