Post the code or shoot it to me via a private email and I will run it
against my database. Another thing is even though your scanning or filters
may not have changed - did you add any additional colums for display that
require calculations?
Each of my scans take on average 4 to 6 minutes.

Dave,
I have held everything constant. I am very experienced at computer use,
so that was the first questions I asked myself. "What has changed?" I can
not figure out what I might have done that changed the scan times from 50
seconds to 5 minutes. I even saved my afls and unistalled/reinstalled the
AB to see I could reset to the original state that gave me the 50 second
scans. No luck. I came to group to see if anybody else had experienced
this type of problem and could provide some insight into the issue.

Hi EF,
That's a fairly typical scan time. Has your filter been set to "all stocks"
the entire time? Maybe in the past you were looking at a smaller set of
stocks? Has your code changed in that it requires more computations now?
Regards,
Dave

Subject: [amibroker] Scan/Explore Times
I have been using AB for about 8 weeks. Really like the program. I have
developed an issue that I have not been able to figure out. I used to be
able to do a scan in about 50 seconds.
About 2 weeks ago, the same scans started to take about 3-4 minutes per
scan. I have tried to adjust my database size, increased the amount of
available memory, increased the number of bars and nothing seems to change
the amount of time needed for a scan
My current settings in Database settings are:
Using the tc2000 Plugin
Local Data Storage Enabled
# of Bars 2000
Base interval EOD
Megabytes 4000
In memory cache 8936
any suggestions on how to get back to the faster scans
Thanks
EF
