The appearance of MS CCI standard, and CCI-Equis diffe from the formula you
sent.
((MP()-Mov(MP(),14,S))/
(1.5*Stdev(Abs(MP()),14)))*100
The "CCI -equis" seems a little closer to yours.
Strangely, the MS "CCI -standard" is less smooth, but less useful at
turning points.

> Usage: CCI( Period1 )
> Returns: Array

> Period1 = number of periods in the CCI calculation as shown below.

> Suggested trading rules are:
> 1. Buy long when CCI goes above +100%.
> 2. Sell long when CCI subsequently returns below 100%.
> 3. Sell short when CCI goes below -100%.
> 4. Cover shorts when CCI subsequently returns above -100%.
