Definitions
In plain terms
It expresses price displacement in units of a scaled recent typical-price deviation.
Technical
The contract freezes typical-price fields, period, arithmetic mean, mean—not standard—deviation, scaling constant, zero deviation, readiness, and adjustment basis.
Scope
CCI is not mathematically bounded and its name does not limit it to commodities.
Formula
CCI = (TP - SMA(TP)) / (constant * mean deviation)CCI_t=\frac{TP_t-\overline{TP}_t}{c\,MD_t}| Symbol | Meaning | Unit |
|---|---|---|
TP_t | current typical price | price |
SMA(TP) | window mean typical price | price |
constant | CCI scaling constant | ratio |
mean deviation | mean absolute deviation of typical price | price |
Output unit: scaled deviation
Examples
- A governed lesson calculates or identifies Commodity Channel Index only after its inputs, window, state, scale, and edge cases are declared.
Common misconceptions
- CCI is not mathematically bounded and its name does not limit it to commodities.

Evidence and governance
- Commodity Channel Index TA-Lib · first party technical publication
Supports: preferred label, short definition, technical definition, formula
Limits: The common 0.015 constant is a convention, and zero-deviation or mixed-adjustment inputs require explicit handling.
