Chuck,
Thanks for the clarification as I was of the belief that QRS was in the ballpark in terms of mimicing the IBD.
Kind Regards,

Ok, Gary.
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.

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" <chuck_rademacher@x> wrote:> Joe,> > I have serious concerns about the formula that you have given:> > RSQP =
