Set up a Back Bet with Greening, and the trigger for the Back Bet went in .....
The only problem is that the Lay (Hedge) bet got taken first So I wondered, is there any way where the Back Bet has to be taken first, before the Hedge/Lay bet is taken?
On the back bet rule, you could use offset bet with greening on the parameters tab
with fill/kill enabled to prevent the offset being placed till the back has been filled
