Download speeds
Good morning,
Am looking for suggestions on
why my data download (Yahoo) takes
so long. I can run the daily download
quickly but if I loose a day
and need to do the historical download to catch up
it takes forever.
It isn't the actual download but the inputting of
the data into AB
that is very slow. Have tried downloading
and then importing. The
download takes maybe an hour the import about 24
hours. It also seems
as slow to do 2 days as 5 years. The
computer is fairly new and has a
gig of memory. Any ideas appreciated.
thanks
John
As I understand the situation, current and historical quotes
come from different servers that operate in different ways. Current
accepts many (perhaps all) symbols and then transmits all data at one
time. This is very fast. The historical server, however, works with
only one symbol at a time. In my case, downloading historical data for a
week takes about 20-30 times more time than a current data download.
Downloading data for a long historical period significantly increases the time.
