I fully support your point of view. Many traders spend a lot of time on their skills, studying information and stuff. I don't argue, it is very important in trading. Yet, for some reason, many people forget that trading is also a psychology. What happens to you in the end depends on how you set up. Have you prepared for the loss of money? And the fact that you won't understand something? It happens that you're doing the right thing, but it's just your unlucky day. In these situations, the main thing is not to lose your temper and to set right. So trading is 90% your mindset.
