I really don't need to open more than 1 position at a time because what I need to do is to produce 5% weekly return consistently. Please note that I really don't need to have 5% every week. I just need to produce average 5%/week consistently.
Trading is a life time challenge. I don't need to prove that I can produce positive result every week. I must truly accept or enjoy losses in order to make profit in long run.
I will be a much better trader when I can feel good about my trading when I have a negative week.
