Have attached the various available CCI versions.
A quick look will let the viewer believe that all are 'one and the same'.
A closer look tho, wil show the differences (in patterns + in values).
The "CCI-Standard" and the "CCI-Standard-custom" differ indeed, but
'only' in values, not in the pattern. Its the closest to, so to speak, that is
available at the moment.
A mail to formulas@xxxxxxxxx requesting Equis to provide you+List with
the code for the CCI-Standard formula, might be of help here
(have cc-ed with this mail).
