Trading tests human nature the most. Once the position is opened and the stop-loss is set, one should not look at it anymore. The more you look, the more anxious you become. This is also the greatest test of a person's willpower. If it were me, I should be able to hold on, because I have always operated this way. Although I am not making money now, if I make the right call just once in a year, it surpasses your countless smart trades every day. You must understand this principle; even if it is wrong, it is also right.
