Lars:
I don't remember where I read that CSI was the
supplier, but FWIW both CSI and Reuters are now listed by Yahoo as
suppliers:

out on Yahoo and see if the same volume error exists, or did CSI correct it
for Yahoo and not for you. <FONT

Subject: CSI I think that
overall CSI is a very good source for data, as some other forum users
have indicated. But just be aware there is one major problem with
their stock data that I have discovered - the volume data is incorrect
if a stock has had a split. e.g. Say a stock trades exactly 1 million
shares every day and it closes today at 20 and after market close it
has a 2:1 split, then next day it starts trading at 10 (or so). Now if
you were to look at the historical volume after the split, you will
still see CSI showing it as 1 million shares, though it should be 2
million (as market cap doesn't change after a stock split i.e. 1
million x 20 = 2 million x 10).
Why is this important? In my Metastock Explorations, I use the 50day
Mvg Avg of volume multiplied by price as a filter to exclude small
caps. Using the example given above, I will get an erroneous result
for 49 days after the stock split.
You can verify this yourself by checking the volume before and after a
stock split by calling up historical prices at Yahoo Finance (their
data provider is CSI); track several stocks about to split starting
today. I have done this a few times in the past and their volume data
after a stock split remained unadjusted for the split (the last time I
did this many months ago; its possible they may have fixed this). I
did call them many months ago to bring it to their attention but the
lady who answered was arrogant and insistent that their data was the
cleanest in the industry and refused to entertain any doubts, so I
just hung up.
Again, this only applies to stock volume data, post-split. I don't have
any experience with their mutual fund or futures data.

If anyone is using dial data and has downloaded the eurocurrency
= symbol E1 ,any month, your data is ROUNDED to 3 decimals.
Dial Data cannot fix this. I was told that they WILL = NOT FIX THIS.
If you are trading off of this data source, then GIGO applies.
If anyone has a moment, please share with me who has been your
BEST = source of reliable, clean Data?? (NOT THE CHEAPEST but the
BEST)
thanking you in advance
