Hello Ed,
Yes, I started from examples in the UKB. I missed the library entry,
however this code is huge and not easy to understand the vars.
Thank you to point this interesting formula, a lot of things to dissect...
One of the many issues I met before to see the Aron's example is in the
following code.
For some reason, the default value is 1 as I expected 10 !
AB's rules have reasons that basic user ignores.
// param static var
pds = Param("pds", 10, 5, 100, 1);
pds = StaticVarSet("pds", pds);
Title = "pds: " + pds;
Best regards
