First post...go easy on me

I have been tinkering around with automation and the question i have is that i have set up a file which lays the favorite, in a horse race,10 seconds before the start of a race (until 20 seconds after scheduled start time) if the odds fall under x in odds. I have also included a rule to place a back bet if the odds go above a certain value.
Now this is fine and works well, however, I want to apply back rules to the second and third favorite if the odds go above a certain value.
In essence i want to lay the favorite if the odds are low enough and if this is the case i dont want the other rules to trigger but if the favorites odds go above a value all the back rules trigger.
I have tried to spell it out as much as I can and any help is much appreciated. BTW I am using the Betdaq version of Bet Angel.
