How do bookmakers make odds?
the odds are firstly set by each bookmaker with regard to each individual horses performance.they in turn compare prices with each other and this is why you tend to get similar prices with all the bookies.when a horse is backed by either a lot of people or there has been some large bets placed,the horses odds will shorten to show the interest in it.it could also be that there has been a few good words from various sources indicating that the horse has either been trained for the race or that it is in good form and expected to do well in the race.bookies get scared when this happens and can dramatically cut the odds depending on where the info has come from.when it comes to the actual race day,prices do not normally open for a live show until 10 minutes before the off.these prices in the time between the opening show and the off are determined by the on course bookmakers at the relevant meeting.this is why there can be horses that go from 20/1 to 16/1 to 10/1 to 6/1 in a few minutes.als
