DBP if you're questioning whether Math and Statopt should be advisors, I'll stick my neck out and vouch that I've had contact with JJ and Greg since 2002 via the TradeStationWorld forums, and in my experience of their extensive posting history there I have never seen them overtly or covertly plug their own interests.
I have the utmost respect for the knowledge imparted by these guys, and I have no doubts about the fact that they are traders of a calibre that can only benefit the membership here at T2W should they participate meaningfully, an opinion I share of yourself too.
