Why don't you check the chart of AVID? I also
found incorrect closing on BVSN on Wednesday.
(This one got corrected later.) There was also
one high/low error on one of Dow stocks which
I cannot remember now. I also reported a
programming bug (not data) to QP this week on
a wrong spilt adjustment. If you are talking wrong
spilt data, I've reported too many. BTW, Nasdaq
volume is not right since a week ago. I normally
don't use QP2's index data, but last two weeks
were extraordinary. I would like to know if we had
reached a short term bottom and to make sure I've not
made any human error on entering data into my database.
I enter volume data of indices by hand daily. On Aug. 28,
Nasdaq was out of Bolliger band second day in a row.
Although we are pretty close to the climax, I've decided
not to do anything with my short positions on the following
Monday based on the volume data I just entered. When I
saw QP2's data was around 690 millions shares, I thought
I made a pretty serious mistake. Later checked Yahoo, and
Nasdaq web sites. Actually Nasdaq was down on very heavy
volume. I could have reached a different conclusion if based
on QP2 data alone. Most of these errors are corrected now.
But I'd like to have clean data when they first arrive, not two
days later. Two months ago I thought QP2 could replace other
major competition. IMHO now, I've better to keep two data sources.
Certainly, I'll change my mind if I don't find any incorrect quotes
in any single week.
