Hi
Attached please find a trigger file that will do what you want.
It will:
Back The Draw 1 minute before kick-off
Green-up during half-time
If greening is not possible at HT, it will leave the back in the market with no further green-up or distribute loss.
In the constant you can set a maximum back price for The Draw
You need to load Match Odds markets.
Please try it in test mode.
