match lay book

Hi,

I need a trigger condition for dutch laying whereby the lay bet will be placed only if the combined odds of the lays is for example between 6/4 and 2/1 (2.50 and 3.00)
The number of selections being layed will vary.

Can someone point me in the right direction here?

Thanks
Larp

Hi Larp
convert the probability (matching selections book %) to decimal odds
100/probability

selections trigger expression 100/match_l_book is between 2.50 and 3.00

Thanks Mark, as usual you hit the bullseye
