<P> In MSWIN 6.5, you can get the 5.11 version using VHF which I think
gives a good rendition. The scaling factor can be a make or break item.</P>
<P>It is a function that you can use in all the Custom Tools (formulas, system
tests, explorations, experts). To use the function you do :
variablema511(data array, time periods).
<P>We can thank Bill Forman at Equis Support for getting us this
item.

PM<BR>Subject: Fw: Vidya and other Chande/Kroll indicators<BR><BR></P>Hi
Max,<BR><BR>The MS interpretation of Chande's VIDYA indicator can be found under
the<BR>built-in VMA moving average. HOWEVER, EQUIS BOTCHED THE WHOLE CONCEPT
AND<BR>IT IS COMPLETELY SCREWED UP! <BR><BR>To see what I mean simply plot a
SMA, EMA, and the VMA of any security<BR>using the same "period" input
for each. Logically, the VMA should be the<BR>most sensitive, almost hugging the
price bars. But as you'll notice MS's<BR>VMA is the least sensitive. In fact,
it's downright dead!<BR><BR>Further, the fact that MS even asks for a
"period" input for the VMA is<BR>dumb, since the "period" by
definition is supposed to be VARIABLE anyway.<BR>The only inputs required under
Chande's formula definitions are for the<BR>"volatility index" and a
scaling factor. MS says it has fixed these as the<BR>9-period CMO for the index
with a scaling factor .78, so no inputs should<BR>even be required. Finally, a
quick glance at the built-in formula given in<BR>the manual shows Equis didn't
even get the scaling factor part right.<BR><BR>Fortunately, the VIDYA is pretty
easy to build and in MS 6.5 the new<BR>"input" function lets you play
around with the scaling factor without<BR>rewriting the formual each time.
Changing the period of the volatility<BR>index doesn't affect the average
significantly. Nor does using different<BR>variables for the index. Afterall, it
only varies from 0 to 1 anyway.<BR><BR>I've discussed this with Equis tech
support when 6.0 first came out, and<BR>they've recluctantly agreed the VMA
might be implemented wrong but<BR>suggested I contact Chande myself to check.
Yeah, right! Too bad, because<BR>the VIDYA concept minimizes the time lag
problems of a crossover system,<BR>and lets you grab more of a price
move.<BR><BR>Hope this helps,<BR>Rick Mortellra<BR>Tokyo Japan<BR><BR><BR>>

Didn't you pretty much say the same thing 8-10 months ago with the DJIA
around 6500?
