I was reading an article about Mark, who is apparently "one of the world’s top traders"; refer link below.
Assuming that Mark is good at what he does, it never ceases to fascinate me, just how common it is for poeple who end up being highly "skilled" traders, to have initially lost significant sums of money as part of their education (Mark states he lost $500k when he started out); almost a rite of passage -- for some at least!
Secondly, Mark devulges his trading secret that places him head-and-shoulders above the rest . . . . . . . . but you'll have to read the article.
