This is a post I have been putting off for a while, as the answer to the question I posed in the title is a difficult and controversial one. It is possible to make a great living trading emini contracts online. The success numbers on such a decision are a bit daunting, though. More than 90% of all new traders bust out in less than three months. Those are not encouraging numbers, and present a pretty tough hill to climb. There are several ways to view this failure rate, and I will try to expound on some of the factors that cause this massive failure in success.
