Hi
As far as I can tell, the trigger is functioning correctly, placing trades on each selection, only when there are no unmatched bets on that selection.
In the attached screenshot you can see profitable multiple trades on both selections.
You can also see an example of an unmatched green-up with the price moving against (arrowed in black). In this situation, it will not place a further back bet on that selection, until the unmatched lay bet is matched or cancelled. Trading on the other selection continues as normal. I think I mentioned earlier the need to address unmatched lay bets, and this is a good example. How would you want to deal with this situation?
Your other question is also shown in the screenshot, highlighted in red. You can view the value of any variable here. In this case it is showing the high back price for each selection during the current cycle.
For the purposes of the screenshot, I have reduced the green-up and qualifying ticks to 2 from 5.
If I am missing something regarding the trigger not betting please let me know a bit more detail.
