I
was reviewing your code for the RS comparison and thought perhaps It would be
be an interesting study for my Sector Rotation work. It Was, thanks! you may
find this variation of use. It provides a visual look at the trend of each
reading. For longer term study you may wish to adjust the ref
periods....

<SPAN
class=266483721-18032003>Question: You had selected 250 as a look back period.
Was this arbitrary or have you done some tests to determine this range to be
optimal??

Re: RSIHello,Comparative Relative Strength
can be useful in deciding which securityto buy, by helping to pinpoint the
best performer. They can also beuseful in developing spreads, i.e.,
purchase of the best performer"long", and selling the weaker issues
"short."Steve, if you load the following into AA , select the ndx100
andcomponets , n last quotation and n=1,click explore...the results
arequite different....also, the RS% value is comparing the ticker
to the INDEX, your value issimply a ROC of the Ticker
itself.Anthonysteve_almond wrote:>
