Tomasz:

Thanks for the answer. If I am backtesting EOD in the evening, nothing
needs to be updated as the Price data will not change. Does something else
change that SHOULD BE updated.

Sounds like I have to get a much faster computer. My 350 MHz is much slower
although it doesn't seem like it. Perhaps it is the defrag.

Ken,

This happens because you have large "in-memory" (RAM) cache.
Once accessed data are stored in RAM for further speedy retrieval.
The maximum number of symbols in "in-memory" cache is controllable
via Tools->Preferences->Data window.

When you exit the program changed data must be stored back to your disk.

Large "in-memory" cache speeds up operation a lot the only penalty is that
saving may take some time. Try defragmenting your hard drive.
On my machine 750MHz Duron/ 40GB IBM Deskstar harddrive
it takes about 10 seconds to save 10000 symbols.

If you click "Cancel" updated quotes are not saved.

Best regards,
