Code from Corey Saxe to the rescue again
HHV(H,LastValue(Min(Cum(1),500)+PREV-PREV));
This has two PREV's in it so you would need to restrict your exploration to
just over 500 (or risk taking forever). Using "Minimum" periods would give
the HIGH for the most recent bar - you no longer have any mechanism to force
a 500 bar scan.
