Quad, Jason,
I’ve been wrestling with almost the exact same issues for the past couple of weeks. In fact, my post of 7:57 this morning is related to this issue.
Quad, regarding comparing Sector/Market Relative Strength against each other… Is this even valid? (No, I’m not trying to be rude.) Here’s my thinking…
Unless I’m missing something, it seems that your underlying questions are, “Which are the strongest and weakest Sectors?” and “How is Sector strength changing over time?” (If so, these are my questions as well.) If this is correct, why do we care about the comparative “Relative Strength to Market”?
It seems to me that the combination of the Sectors IS the market. Correct? If so, then the Sectors’ comparative ROC or RSI is a valid measure. Or, perhaps calculating the rank of a Sector within all Sectors using ROC or RSI. Do my arguments make any sense?
I’m using TC2005 data also and the Sectors/Industries are one of the key reasons that I used the data. I’ve got several indicators built that calculate Industry and Sector rank and comparative strength. I use ROC and RSI for both. I’m VERY interested in improving this.
Jason, this looks VERY interesting, but there are two issues:
1)
2)
3) I’m a little confused about using this as a scan. I.e. it looks like the code computes the relative strength of the Nasdaq index to the S&P500 and it’s changes over time. But that wouldn’t that only return one row?
Inquiring minds want to know. J
Regards,
Dan.

Subject: Re: [amibroker] Question on RS, possibly for Tomasz
I've got a number of different RS-type explorations that I've been experimenting with. Try this scan - it's by no means perfect, but you can modify it to fit your criteria. A quick warning though, this formula works fine on my home PC but at work I had to play around with "j" because it wasn't recognized as a valid symbol...strange.
Filter=C>0;
x=RelStrength("!comp");
j = Foreign("!spx", "c");
j1 = RelStrength("j");
j2 = RelStrength("j")/Ref(j1,-20);
j3 = RelStrength("j")/Ref(j1,-30);
j4 = RelStrength("j")/Ref(j1,-50);
j5 = RelStrength("j")/Ref(j1,-100);
j6 = RelStrength("j")/Ref(j1,-120);
j7 = RelStrength("j")/Ref(j1,-150);
j8 = RelStrength("j")/Ref(j1,-200);
vol1 = StDev(log(C/Ref(C,-1)),720) * sqrt(260)*100;
vol2 = StDev(log(C/Ref(C,-1)),20) * sqrt(260)*100;
vol3 = StDev(log(C/Ref(C,-1)),50) * sqrt(260)*100;
vol4 = StDev(log(C/Ref(C,-1)),90) * sqrt(260)*100;
Vol5 = (Vol2 + Vol3+ Vol4)/3;
Vol6 = Vol5-Vol1;
Final = (j2*1) + (j3*1.2) + (j4*1.3)+(j5*1.4) + (j6*1.5) + (j7*1.7) + (j8*1.7);
RSC=LinRegSlope(x,7);
AddColumn(IIf(rsc>0,BarsSince(rsc<=0),BarsSince(rsc>=0)),"Cross",1.0);
AddTextColumn(FullName(),"name",5);
AddColumn(FINAL,"Today RSC",1.2,colorDefault,IIf(final==0,colorBlue,IIf(final>Ref(final,-1),colorGreen,colorRed)));
AddColumn(Ref(final,-1),"Yesterday RSC",1.2,colorDefault,IIf(final==0,colorBlue,IIf(Ref(final,-1)>=Ref(final,-2),colorGreen,colorRed)));
AddColumn(Ref(final,-2),"2 days",1.2,colorDefault,IIf(final==0,colorBlue,IIf(Ref(final,-2)>=Ref(final,-3),colorGreen,colorRed)));
AddColumn(Ref(final,-3),"3 days",1.2,colorDefault,IIf(final==0,colorBlue,IIf(Ref(final,-3)>=Ref(final,-4),colorGreen,colorRed)));

I would like to do an exploration for the change in RS of a sector
over various periods, say one week, two weeks, etc. I extracted the
RS of the sector versus the S&P Equal Weight Index using:
Strength = RelStrength ( "SPEW-X", fixup = 1 );
Then I found the change over the time periods in question.
Of course, when you look at a plot of the RS for a symbol or sector it
appears the numerical value of the RS is directly correlated to the
price of the
underlying. Thus, the numerical change in RS would be
meaningless against a different priced sector.
I thought the simple solution was to divide the RS value by the
closing price, thus normalizing the results. But this caused the RS
charts and values to be identical for every sector.
Is what I'm trying to do an impossibility with Amibroker or is my
approach all wrong? Any help would be appreciated.
Thanks,
Bret
