Thanks Bill, that helps a lot. Your knowledge of the inner workings of TS
is several levels above mine. Have you written about this trick you mention
in #3 below (of using a function and an Include System) in your Tradestation
newsletter "TS Express"? I don't remember seeing it.
Jim
P.S.
To all: Good newsletter for active TS users. No affiliation.. blah,blah
