I have been trying to work this trigger out all day with no luck.. Doing it manually is time consuming even though it has a great track record.
What I am trying to achieve is this;
Remember the fav (Rank 1) just before the race goes into play.
IF the fav goes to rank 3 (3rd fav) in-play then place a lay bet.
30 seconds in-play to let the odds settle down
