Ok,

I
guess that the translation may be correct and that the QP QRS thing may work,
but I have trouble understanding the relevance of the performance of a
stock between 250 days ago and 189 days ago. But, what do I
know? What I do know is how IBD works and the QRS thingie doesn't
even come close.

Please
don't get me wrong here. I'm not saying that what was submitted is
wrong or that it won't work. I just stated that, to me, it seems
illogical and to call it IBD-like is a bit inaccurate.

[amibroker] Re: IBD InterestChuck,The formula
Joe has posted is a straight translation of QP QRS ranking. I
certainly appreciate your thoughts and modification to the formula as I'll
that as well.Regards,GaryHere's info on QRS from the QP
help file:Quotes Plus Relative Strength IndicatorThe Quotes
Plus Relative Strength indicator is calculated for each issue each day,
and becomes part of the data you download to your PC. The indicator ranks
each issue in the database against every other issue in the database,
based on its performance for the last 12 months.Every issue is
ranked from 0 to 99 so that its rank is equal to the percentage of issues
that it has outperformed over the previous 12 month period. A rating of
92, for example, means that the issue has outperformed 92% of all of the
issues in the database.The formula is :( Current Close / Close
from 62 trading days ago ) * .4+ ( Close from 63 trading days ago / Close
from 125 trading days ago ) * .2+ ( Close from 126 trading days ago /
Close from 188 trading days ago ) * .2+ ( Close from 189 trading days
ago / Close from 251 trading days ago ) * .2This value is sorted for
all of the issues, and the top 1% of issues get a value of 99. The other
issues are ranked similarly, down to the bottom 1%, which get a value of
0.--- In amibroker@xxxxxxxxxxxxxxx, "Chuck Rademacher"
