I suspect that you are mixing up Barcount and
Barindex(). Barcount returns number of elements in array.
Barindex() returns array. Your example does not initialize TestArray[
].

LOL well which is
it? Neuro said (and I understand the documentation
to read) that
arrays are initailized with barcount elements.
Therefore I should be able
to access the 800th element of an array
when I am using a ticker with a
barcount of > 800, correct?
By the way my ultimate objective
in all of this is to get this script
to run against my watchlist of the
S&P 600 Smallcap index:
