Also if I may, could I ask for a slight tweak of this trigger
No horse must be odds on at the start of the race. i.e. all horses must be 2.00 or bigger at the off otherwise no bet.
Also, the trigger must only be set to work on the pre start favourite of the race. So it is not the first horse in play that goes below 2.00, it is only triggered if the pre race favourite hits odd of 1.99 or lower in play.
Thanks
