Loaded QP2 friday & updated data. Help file implies Virtual isn't supported under NT4.0 (says only supported under windows 95). Anybody know if this will be the case?
Also, anybody notice the index data corrupted? !COMP now shows volume (which is nice), but 6/8,10,11 are missing the volume. !DJ30 is all there w/ volume. !SPX only has about 50 days of data and no volume. I have a 6/10/98 program disk. Probably more, those are the only ones I've tried so far.
I was hoping the scans would make better use of available RAM, rather than doing the dreaded "disk sanding routine" again (disk access for each symbol's data as it's used, as in the old QP)
To get an idea of the speed difference this can make, start a scan, and let it run through a few hundred tickers (depending how much ram you have), then stop the scan in midflight. Then restart it. All the data up to the point you stopped it at is in memory so no disk thrashing and much faster until it finishes what was in memory.
Anyone (Gary???) know if there's a reason the program can't retrieve large blocks of data (based on available system memory), then operate on that data out of ram, rather than disk accesses for each symbol? Or 2 blocks: a working block and a loading block that loads in the background, then the blocks swap functions when one completes?? Scans would be MUCH faster, and you hard drive would thank you!
