I would almost pay real money to take part in those leagues, especially the H2H leagues haha. You could even add onto it with the idea of teams within H2H. Imagine this possible twist: 16 teams of 10 HSX traders each (Sign-ups could be held a week or two before). Each week one team faces off against another team. The team (either by total profit or total percentage) that comes out on top gets a point added to their win column. After a season (like you mentioned), the records are compared. Playoffs are set, championships won, etc. Oh, think of the possibilites...
As you can tell, I'm pretty excited about this concept of leagues, hahaha.
Looking forward to HSX rolling out with some of their new and exciting ideas for leagues as well. Please keep us posted HSXToby. This could really be a way to keep old players interested as well as drawing in first-timers.
