ok confused againt, if i'm paying someone the lay odds.. then why are the back odds different? Also is the money under the odds the total money that has been bet at those odds? So if say lay of 730 is showing only 5, for me to get matched i'd have to play a lay of no more than 5 units?

Who sets these odds and how come the lay odds would differ from the back odds? Who is getting the payout of 730 when the back odds shows say 38

I use that adelaide race u mentioned as an example.
No 10 Benefit Road is showing a back odds of 38 and Lay odds of 730. Why isn't the back odds 730? As thats what I'd have to pay you if you were to back Benefit Road. Instead if you were to win your back bet you'd only get odds of 38..
