Identifying Favourite and underdog throughout a tennis match

Morning All

I'm struggling to come up with the best practice of trading on tennis matches based on favourite/underdog status at the start of a match.

The problem I have is that I want to base my triggers on their respective positions at the start of the game so that I can action something in-play even if their respective positions have changed ie the underdog in now the favourite.

Any ideas on how I can best identify them as fav/underdog even when their positions have reversed in play?

There are 2 useful trigger variables:
1. actual_sp if the market supports SP betting (the condition for the favourite should be "Any selection's actual_sp is the minimum")
2. last_order - the order of the selection before the off. 1 stands for the favourite. ("Any selection's last_order is equal to 1")

Excellent, thanks Tim. I'm sure I read somewhere at sometime that Tennis matches don't support SP but the other option looks perfect.

Many thanks
