Decode IBFX contest (I)

IBFX is holding a contest for its mini account which requires a min 250 deposit. The contest is calculated each month based on percentage return. Top 5 would be awarded cash directly. 

Several interesting thing can be observed from the historical results. 

1. The top 5 or so usually would dramatically outperform the other guys. They usually would at least double their assets. The top 100 can at least have a 10% return. 

2. There are always guys who blow up their whole assets. Even worse, someone can lose more than they have. This may be due to a terrible bet on the Friday close. 

3. If the contest participants can be viewed as rational sample of the traders at IBFX. Then definitely the broker woule earn a considerable amount from both spread taking and holding the opposite portfolios to the traders'.
