Tradesports, just as every brokered mkt, is negative-sum; by defintion, some capital is removed from the game upon settlement of every position (commission, fee, call it what you will).

I don't object to their charging a trading fee, of course. I do object to the clear and obvious game theory mischaracterisation you offered.

Yes yes, it's zero sum less the house rake. I thought that was obvious enough to go without saying; apparently I was mistaken.
