I do not think it is necessary to sit still in front of the chart all the time for trading.
Because all the time the market movement is not good, so if we can choose a special time to trade,
we can generate good profits. I like to trade overlapping sessions meaning when the
London & New York session is opened (GMT 12: 00-16-16: 00), because at that moment
the market movement went well along with the many traders who traded back then.
Asia's opening session is also safe to trade.
