hi
with your first bet trigger, you could try this condition
and selections back matched is equal to 0
your second bet trigger.
and selections number of matched lay bets is equal or greater than 1
i have put is equal or greater than 1 just in case the greenup has split lay odds resulting in more than 1 bet to greenup.
this should place your first bet then greenup then place the second bet and greenup.
BUT your greenup trigger must have the conditions
and selections lay unmatched is equal to 0
and every selections profit and loss is less than 0
set the trigger to once every .5 secs
so it will only place bets to greenup if there is any selection with a minus pl
USE TEST MODE FIRST
