I disabled the O1.5 trigger as the rare 0-1 final score still eats most profits over the long run, just like in laying the 0-0 score line does. Maybe look into backing O2.5?
The trigger is profitable if you pick the right games. These include the major leagues, so don't use U20, cup games etc.
The trigger could be modified, say green up when 1-1 score is achieved, rather then letting it run until FT.
By placing the trigger on the forum I am looking for input on changing it, making it better, removing any errors in it etc.
