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:
