I'm looking for a site that will give me the Bookies opening market/odds/quote, call it what you will.

Some sites give the market for some races but not all, such as IAS and Sportsbet,

at Caulfield there is no market for races 7 and 8

at Randwick no market for race 1

Doomben no market for race 3 and 7.

Why do they do this?

Where can I find the bookies opening market for all races?
Or if you use one which one do you use?

Cheers,
Mike.
