Hi
Try this trigger in test mode. You need to load the OU 1.5 markets before the start of the game.
Here is how I understood it:
Back in Under 1.5
at 60 mins
score = 0-0
WOM is greater on back side (I made greater than 0.50, you can adjust this)
Green up to min 5%
No stoploss if goal is scored
I'm sorry I did not understand "after making the lay under 3.5 to 1.01 at half green"
but I hope the attached trigger will get you started.
