Yea, I completely agree with you and this is not just the first time I am hearing such idea about trading. A trader that I know only takes one trade every day and the best time he takes those trade is during morning. Before 12pm, he is already done with his trade and has taken profit and wait till the next day. He said the reason is because he has more peace to make accurate trading decisions in the morning and it is more accurate if he only takes one trade. I am trying to teach my self such habit.
