looks pretty decent,
I dont think the liquidity is real as there is fortunes waiting to be matched on every market.
wat happens is say I back the Miami Heat @ odds of 1.7 and they go 12 points up in the 2nd quarter, there odds would drop to say 1,3 so i can lay them off for a guarenteed profit.
there is a small section that shows you your profit.
dont think american users are welcome, not sure though.
anyone used this site?
