Well... it takes me about 4 minutes to download the data for several
thousands futures (including comodities) and something like close to
60000 stocks.
The software downloads all the available symbols every time from the
CSI servers. Disadvantage: indeed, slow because it downloads everything,
downloading only a selection would take shorter. Advantage: every day
i can select the stocks i would like from the database of 60000 without
me needing to download again... and again... and again.... So for me
4 minutes a day is fine specialy since it's EOD data and i can dowload
it while the market is closed. Probably you can even let your pc do it
at night...

I would hate to have your trading day if you don't have a spare 4 minutes
a day.

Yes, they will lock you out of new data. If you have created a portfolio
wich saves the data into ASCII files you will not have that problem. The
data will stay there and will not be deleted.... even if it would, you could
make a backup of those ascii files.

Monthly price is lower indeed. But that seems to be only for the daily
updates. You would need to pay an initial fee i think for getting history.
CSI delivers 10 years of history for all the thousands of futures and
thousands of stocks. On the other hand, if you buy history with
pinnacle it looks like the history goes further back for a lot of the
databases. However, getting history on everything would cost $645
But agree, monthly fee's are a lower. Latest test i have seen on
reliability was in favor of CSI but that was a test in 1999. don't know
how that is nowday's.
> btw you can get csi data for free from yahoo.com why pay bob?
Because getting it for free would make it even much slower. Daily
updates (downloading only the last day) is not alway's reliable because
updates are not posted on a set time. Specialy not 15 minutes after
the closing. It might take hours before the data is posted on the website.
Strange enough Yahoo updates the historical files faster. So a good
idea would be to download the complete history each day. (special
because of stock splits etc this is a good idea) Downloading complete
data each day will take longer than 4 minutes. In those 4 minutes
CSI (and probably also pinnacledata) will correct all errors found and
will do stock splits etc. etc.
so the free source is not as good as the paid source. As it should be...
