trigger help- easy green up math

i know its simple but i cant get it

so ive layed then backed, generated a profit and want to split that profit for that selection only, so if it wins or looses the profit is the same.?

thanks

sorted..

(bm_laya*bm_layp)/back_price

Why not use green-up Action!

i want to do it in a certin round, which auto GU cant do
and
i want to keeo the spread with the selection i traded, not spread over the field..

I know this is old post but anyway - what's the formula for manual green up for backing then laying?
Thanx

I usually recommend another site but have lost it for the moment. This will do, I think :

Thanks Mark, very helpful. I wonder if there should be a FAQ thingy here. Posts such as that are very helpful and were made before I came here.
