hi
here is your trigger , there are 3 new constants to set.
Take a loss profit percent
Maximum favourite back price
Maximum tick difference between the back and lay price
I have added the favourite price to help with choosing the correct third fav and the tick difference because many times there was a low back price with a high lay price so the distribute loss kicked in straight away.
please use test mode until you are happy with your settings
