Hi Darkhorse,
ok this is not too difficult although in running, winners often come in below even, right down to your 1.3 , go back out to anything like 10/15/20 and then rush back in and win.
This would mean your potential liability could be enormous, but that's what TEST mode is for
All you need to do is create a second trigger, that places a lay bet at 6's, on any selection with a matched back amount and price greater than 5
So
Action = Lay
Markets = Horse Races
Status = In Play
Price = 6
Selection = First matching selection
Amount = up to you, I would simply cover your loss on the back bet, so enter bm_backa
Conditions
Any selections back_matched is greater than 0
AND fitting selections back_price is greater than 5
Hope this helps, anyone else reading that see's a better way please post!
Cheers
Rich...
