Trading does not depend on psychology. Gaining profit or loss from trading depends entirely on the experience of the traders. One person has enough knowledge about trading and understands the charts and when trading is likely to be profitable, and another person who has no knowledge or experience in trading trades based on guesswork. Whose money is at risk here? There will be and chances of a person making profit is definitely the first person because the first person is not making a trading decision depending on his own luck, he is using his experience and having an idea about trading and then trading. So trading is never dependent on psychology.
