I earlier posted a question concerning volume data results from the functions qp_volume(0, "!dj30"). No response received.
Specifically, 28 Mar 08 Dow30 volume was 209,002,369 shares. Quotes Plus reports it as 548,731,000 shares. Big difference. Why the difference in these numbers? Can it be corrected? I use historical index volumes as reference points in my real-time trading software. The Dow30 number is noticeable. Thanks in advance.
