It doesn't take balls 95% of the time, I am extremely risk averse. Consistent, daily profits is what I am after. However, Once in a while you do have to make a bet when the elements are overwhelmingly in your favor, such as yesterday. But it really didn't take balls, I've built up enough profits that I was willing to make a big trade, and I executed it well!
Good trading to you!
Mike
P.S. Yesterday's trade has been 3 years in the making!
