Reverse market-selections order

[jimibt]

Evening all...

just a super quick question that hopefully requires no devious workarounds.

i have a small section of a rule that requires a cross check by navigating the selections in reverse order and tallying their book values (i.e. starting at the highest odds selection and working back up the list). i'm looking for a way to do this inside a small one liner rule in Guardian but can't see a way to loop round the selections in reverse order. I don't want to resort to excel and the end game is to match up to an approximation of something that I do using the API (which is simple as i just reverse the order of the list by odds value).

Any SIMPLE thoughts on this out there using BA/Guardian only??

[edit] - i've thus far discounted creating individual lines from xx down to x where a signal is decremented as each placeholder position is tallied. BUT if that's the only way to clumsily do it, then i'll be done with it!!

ok, had to resort to the more verbose xx->x entry per selection to achieve my simple summed amount in a *loop*. anyway, problem solved.
