Even if you have great self control trading will make you forget it. I am talking from personal experience here, I remember very well when I was trading and I couldn't even sleep at night. At 2 am in the morning I used to woke up and to check my positions in trading. That's how obsessed with trading I was and that lead me to losing everything. Now its been about 3 years I have fully recovered from this disease as that's what I will call it, a big disease. I want to tell anyone to stop trading as you will never come on top of that no matter how skillful you are. Ask yourself a simple question , if trading was so profitable for the traders would there be so many trading houses and websites out there ? I don't think so. Trading truly is unpredictable.
