Dear Barry,
Let me add to your worry. How about after hours trading? How we going to
count advance/declines issues and volume (TRIN is derivation of it) in
after hour trading? WSJ reports them separately, so if you want to
"compose" A/D issues and volume with "normal" trading ending at 4 P.M.
(like you would do add composite trading closing prices to the NYSE closing
prices) you can not unless you are willing to count advanced/declined
issues yourself after close of evening trading.
Ponder it over weekend. What do you think?
Bewildered Alex.
