class=890060615-19032003>Keith,
As you
point out, the results are very similar. The leaders and the laggards are nearly
identical. The difference tends to fall in the middle. I continue to use the RSC
as I view the ROC component to be an important one in measuring the nuances of
an advance.
<SPAN

<FONT
size=2>Someone (I believe Anthony or Herman) had suggested that dividing the
close value by the symbol count would aid in smoothing out extreme moves
of component stocks of the indexes. It makes sense and I have modified the
code to reflect that. If you are using the RSC code to view sector indexes
rather than stocks you may wish to modify the code that generates your
composites. Simply change the volume component to read <FONT
color=#0000ff>
AddToComposite(<FONT
color=#ff00ff>1,<FONT
color=#ff00ff>"~index",<FONT
color=#ff00ff>"V");
This
serves as a counter during the composite construction. The RSC formula would
then read....
<FONT
color=#000000>
Filter=C>0<FONT
color=#0000ff face=Arial size=2>;<FONT

x=Foreign("~index","C")/Foreign("~index","V"<FONT

RSC=(ROC(MA((C<FONT

AddColumn(RSC,"Today

The
blue line will reflect the index universe, green shows the sector advancing over
the previous time frame and red declining. Depending on your time frame you may
wish to adjust the ref periods.......

If you
are simply reading stocks the original code is fine.

RSC afl which you submitted in #34763. I have found it most useful.When
I run your code below on the NDX it produces very similar results to the RSC
formula in #34763 although there are some differences.Does the earlier
RSC afl which includes the ROC function have any particular advantage over
the code below?Keith--- In amibroker@xxxxxxxxxxxxxxx,
