So you can trade for guaranteed profit a lot on Betfair which is nice.
A couple of MMA related things to know about Betfair is that you can not get the opening lines, for example you have already bet on Ryan Bader at nearly +300 but Betfair does not have UFC126 market open until UFC125 is finished.
The only props you can bet on is how a fighter will win. I think they only offer UFC betting, I had to request some lines for WEC 53 so they put them up.
