Hi
If there is a gap in the prices, and you put a back bet 1 tick above the best back price, you are not going to get a value price. The way the trigger works at the moment is that your back bet will appear on the lay side always 1 tick better than the best lay price. This is the correct way to do it.
Back Lay
1.75 1.98
if you back 1.76, 1.77, 1.78 it is bad value.
if you back 1.97, 1.96, 1.95 it is good value. This is how the trigger works now.
For the lay bet, you should offer 1 tick above best back price for better value. I will add this to the trigger and post when it is done.
