Simple trigger help needed please....

Hi, I am relatively new to MF Pro, have been using another bot which I think I have now outgrown. I need a trigger which I think is quite simple to do for someone with a bit of experience but I have none at all.

Back 'selection' if odds greater than 'x' for target profit = '% of bank plus any previous loss recovery' If selections odds are less than 'x' then back 'my 2nd choice'

For this to be repeated until '£x' has been reached then stop or 'x' number of losses then restart cycle.

Does that make sense? I know what I want to say but after reading that back I think I have confused myself!!! lol

Your help would be much appreciated !
