Hello. I downloaded 360 symbols, intraday tick data for 2 days last night. I started at 9:53 PM, and it didn't finish until 11:47 PM. Nothing was wrong w/my internet connection; it was fast. Any idea why downloading historical data is so slow?

Sorry for the delay in this response. I need some more information before being able to look into this further....

Do you run this same batch of processing every night?
Was last night the first night you saw this happen?
How long does it normally take you to retrieve this data?
Do you know which server farm you were connected to?

Thanks for your response.

Here's my log file. I also had trouble connecting as you can see. It is always pretty slow, however last night was the slowest I've ever seen it. In the past (on 05/03/07), 1 day has taken from 8:34 to 9:15 PM just as an example. I do not run the same batch every night, I pull up a list of stocks based on criteria & run it when I have time that day (always after 7PM):
