I have betting for years now. I had a great year last year!!!!! I hit all most 60% last year over baseball and football. This year has been average at best. Considering that living here in the US i do not have very many exchange options. HOWEVER! I am a little confused. I use to dabble with WSEX and Trade Sports. They did the whole contract thing 1 - 10. Win it expires at 10...well you guys know. I'd but at 6, as the game pregressed I could get out at 8. If it dropped, I could get out and buy the other side. This I understood. I do not get how to do it with odds though. Lots of the sites always have a few... in play or live games. But the odds just change. From say -110 to -175. Can someone tell me how to "trade" it?
