Dave, Yes, if you read the text of my last post. I saved the database after scan 1 and went to scan 2(different scan) and saved database again. By scan 3 (again a different scan), I was back down to Avg speed of 50 seconds for all subsequent scans.

Tomasz mentioned that I might have been scanning against a native database. No, I have always scanned against the TC 2005 database. But what I did do, was after I had done my first scan, I saved the database. Next scan which was a different from the first scan occurred in half the time. Saved the database again. My third scan (again different from the prior 2) occurred in about 50 seconds. All scans from there, occurred in about the same time. I am scanning the TC2005 database group of stocks in all cases.

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.

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.

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?

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 Please note that this group is for discussion between users only.
