You're right about making the number of days/quarter more accurate. I just
checked Daily Graphs Online and they say
Relative Price Strength (RS) Rating or Relative
Strength Exclusive rating in Investor's Business Daily. This
IBD SmartSelect® Corporate Rating measures each stock's price performance
over the latest twelve months compared to all other stocks.
so I don't know if they ignore stocks under $5 or not. Anyway, for going
long, try using a buy-condition and optimizing the quarterly growth number >
opt for opt = Optimize("opt", 1, 1, 2, .1). Also, try a buy-condition with
quarterly growth in a range, like 1.0-1.1, 1.1-1.2. I believe I use a filter of
quarterly growth > 1.15 or so, and am wary when it gets too big, like
>1.5.
Quotes Plus has RS-rank that we can use, but it only goes back to 1995. I
didn't think that was enough when I started backtesting a couple of years ago.
Now, it includes a bull and bear market, so maybe it's enough.

Mike,
A nitpicking question. Wouldn't it be more accurate to assume 22 rather
than 20 trading days per month in your formulas (or better, 64 trading daysper
quarter)? Also, doesn't IBD ignore all stocks whose prices are less than
$5/share? Thanks.

There are two kinds of relative strength. The relative
strength graph thatis shown on IBD graphs is built into Amibroker as
RelStrength(). The RSranking number is made by calculating an averageof
quarterly growth ofprice, then sorting by that number. The top 10% would
be RS rank 90+.Mikeqtrgrowth = (2*C/Ref(C,-60) +
Ref(C,-60)/Ref(C,-120) +Ref(C,-120)/Ref(C,-180) +
Ref(C,-180)/Ref(C,-240))/5;Plot(qtrgrowth,"qtrgrowth",1,1);-----

PMSubject: [amibroker] Relative StrengthIs there any way to
calculate or approximate a stock's RelativeStrength as defined by
Investor's Business Daily (i.e., the relativeprice performance of a stock
in comparison to all other stocks)?I tried using RelStrength
specifying the Wilshire 5000 Index (thebroadest market measure I am aware
of), but when I sorted theresults by the RelStrength, it was apparentthat
the order wasdirectly proportional to the Close price. Then I thoughtI
couldnormalize it by dividing by the Close price, but the results of
doingthis were 0.09, 0.10, or 0.11 for all 8,876 stocks -- not a
usefulmeasure.Am I missing something
here?Thanks,DamienYour use of Yahoo!
