Sigh, you shows again how much you don't know financing

no wonder you think it's okay for China to have 150/barrel. To you, you want to sound like a pediatrician has more knowledge than a derivative financial quantitative analyst and modelist. And with your arrogance, you even imagine that they knows less than you do. When I tried to explain to you, you keep laughing as most kids do, and you never really understand what I am talking about. That's how deep our knowledge gap is. I advise you to go to B-school as a minimum requirement. After your graduation, people may take you seriously.
