Match Greyhound win market to Quinella and Exacta Markets

[Bascoe]

Hi all, I am looking for a way to match different markets for the same race. I have a market id for a Greyhound race - it is "1.216323684".
Knowing that, I want to be able to reference the corresponding race in the Quinella and Exacta Markets.

I have found, on a quick inspection that the markets are numbered sequentially thus:

Win 1.216323684
Top3 1.216323685
Ex 1.216323686
AvB 1.216323687
Qu 1.216323688

If that is the case I have no problem. However, I am not sure if this is a strict convention that I can rely upon.

How have others addressed this issue?

I would expect the norm to be
1. get an event
2. get all market catalogues for that event
3. for required markets get market books

You seem to be working backwards.

Thanks Jabe, I have only been betting in win markets for years, so what I normally do works fine. I tried your suggestion, thanks that looks like the way to go for multiple markets, thanks.
