Dick:
You are downloading a very large number of quotes
from Yahoo. Were you downloading historical (CSI data) or current
(Reuters)? Historical is very much slower than current because of the way
the server is accessed and, imo, need only be done once per week (e.g., on
weekends), if one wants the final database to be CSI. I am on a relatively
slow dialup connection and current downloads at a rate of about 1000 quotes/min,
whereas historical is perhaps two orders of magnitude slower. Both data
suppliers are quite reliable and the majority of the current equity and
index quotes are available about 20 minutes after the market closes. No
significant problem after operating in this mode for several years. From
your description, my guess is that MSOdata's servers operate like Yahoo's
current server.

Updates
Joe,
I switched over to AmiBroker about 18 months
ago. I use the US Stocks
database. With Yahoo it normally took from
1 hour to 2 hours to
download (sometimes up to 6 hours). About the same
for MetaStock
using their downloader. this is with dial up. After a
number of
itermittent problems with Yahoo I swithed over to MSOdata. It
takes
about 3 minutes to download the 5,700 US Stocks database. You
then
parse the downloaded ASCII data into AmiBroker though the Wizard
(about another 5 minutes). Just a suggestion as Yahoo is
unpredictable.
