Each round will consist of up to 5 trading days (so in other words 5 days worth of picks). However, it will be a done on a best of 5 series, so the participant who wins the first 3 daily challenges over their opponent wins that round and advances to the next round. Originally I was thinking of just simply using the total ROI of the members picks during the 5 days stretch, but I think using daily wins to decide the winners will be used in this exercise.
