function:
<SPAN

<SPAN

array.'Avg' is also known as typical price:Avg = ( H + L + C ) 
/3"
<SPAN

<SPAN 
class=964101617-01072004>So as far can see, the built in CCI already is doing 
what Woodie's CCI does in that respect.

<SPAN 
class=964101617-01072004>I did see the 0.015 factor mentioned on the Woodie's 
site, but I don't understand what that's about. How does that "normalize" 
anything? The plots of Woodie's CCI show it running in the same range that I'm 
used to seeing for CCI values; it doesn't look like it was multiplied it by 
0.015. Do you have more info on this?

<BLOCKQUOTE 
>Many 
  thanks for your reply. I read the description of CCI function at the AB 
  website. As I understood it, the CCI function in AB calculates the price 
  based on closing price (CLOSE) and the other function CCIa uses H+L+C/3 
  (average of High, Low, and Close price values). Woodie uses CCI that is 
  based on H+L+C/3. In order to be consistent I want to use H+L+C/3. I will 
  be grateful if you can tell me how to modify the code you have described 
  to:1) plot the CCI based on H+L+C/32) eliminate the Turbo CCI 
  (i.e. the 6 period CCI)Can you also tell me if the CCI and CCIa 
  function in AB use the 0.015 factor in their calculation to "normalise" 
  the CCI?Many thanks in 
advance.Sincerely,Rama.
