Dutch odds formula

Hi ,

how can i get a dutch trigger to only bet if the return on betting on both selections is 1.30 or better? so if the combined odds of dutching both selection  is equal or greater than 1.30 then action else skip the race

Hi
It will be 100 divided by the combined back odds of the matching selections to get the book percentage.

100/1.30 = 76.92

so the last condition in your dutching trigger would be:
and selections trigger expression match_b_book is less than 76.92  

Thanks MarkV as always for helping!
