Hi Tomasz,
(Marcin, you can close [#25228] MTMACD problem)
Argh. You are right of course. Perhaps the instructions might be
refined just very little bit, to keep other programming illiterate
types like me from falling into a similar trap. ^_^
I had actually discarded the original scan file, thinking it was not
necessary to retain, somehow, based on the following line in the
instructions:
"Note that we are using Foreign function to retrieve indicator values
stored in artificial ticker. That way we don't need to re-calculate
it."
I realize now that this line in the instructions applied to the plot,
not the scan. But it's rather ambiguous (to me, anyway),
particularly when no mention is made that I can find about how often
rescans need to be done, nor exactly what settings should be used
when doing them. Yes, 1-minute is specified, and I made sure of that
when I set it up. But 'all quotations', or a subset? I'm guessing
'all' the first time, then perhaps 'n days = 1' on a daily basis. But
I cannot find these instructions in the document. Re-reading it,
helps, but it is not precise (some details seem to be missing),
except to those who understand programming.
This is a very nice piece of work, as I mentioned before. But since
it needs to be rescanned, and since the rescan takes about 13 minutes
on a P4 2.53 GHz using 100 percent of the processor, I'm not likely
to want to do this very near the close, when it would be most
effective. *Any* suggestion you might have (other than buying a
supercomputer) ^_^ to cut the scan time down would be appreciated.
I'm scanning 196 equities, is all.
