Hi mcbee,
I was still having trouble in the end, i worked on it all weekend with me head in the manual and looking through example triggers with no look.
So i decided to create a seperatd back trigger so if i want it to b,b,l then have 2 back triggers and 1 lay trigger, then a trigger each for them aswell to check settled market for each, then set a static number so 1st back bet loses then bn=2 if 2nd back bet loses theb bn=3 then lay bet is triggered.
Using bn+1 is more versatile but very unreliable, what i found is a trigger wont fire just 1 time, it was firing 4 to 5 times then bn was 6 triggering a lay bet regardless of the last market outcome.
Just letting you know, maybe just a fault with my settings not sure but works now solid.
