Compute the mean deviation of the n most recent typical prices:
Compute the Commodity Channel Index:
CCI = (X1 - X) / (0.015*MD) ...

Calculate the Mean Deviation. First, calculate the absolute value of the difference between the last period's SMATP and the typical price for each of the past 20 periods.

Then we will add the values and divide by n to find the "average deviation" (Mean Deviation) (2).
(*) The absolute value of the difference between a course and the average corresponds to the distance between the current and average.

Third, calculate the Mean Deviation which is the sum of the difference between the last period's SMATP and the typical price for each period of the CCI periods divided by the number of periods.

where n = CCI Period
MDTP stands for Mean Deviation of Typical Price
CCI = (TP - MATP) / (MDTP * 0.015) ...

The CCI is calculated as the difference between the typical price of a commodity and its simple moving average, divided by the mean deviation of the typical price. The index is usually scaled by a factor of 1/0.015 to provide more readable numbers.
