Commodity Channel Index (CCI): Uses, Calculation & Examples

Commodity Channel Index (CCI) is a momentum oscillator used to identify trend strength, overbought and oversold conditions, breakouts, and potential reversals. By analysing price deviations from its average, CCI helps traders identify entry and exit opportunities across different market conditions.

The Commodity Channel Index (CCI) is a momentum-based oscillator developed by Donald Lambert in 1980 for cyclical commodity markets. But it is now widely used across stocks, indices, and currencies. Traders use it to spot trend changes, see whether an asset is overbought or oversold, and measure the overall strength of a price move.

What is Commodity Channel Index (CCI) Indicator?

CCI is an oscillator, and like most oscillators, it was designed to give traders a broader understanding of overbought/oversold levels by measuring how far the price is from the MA (moving average). Namely, normal deviations from the Moving Average (MA). The formula for Commodity Channel Index is given below.

CCI = (Typical Price−SMA(TP,n))/(0.015×Mean Deviation)

Where:

• Typical Price (TP): High+Low+Close/3
• SMA (TP,n): Stock price Simple Moving Average of the Typical Price during n marks (implicit default is n=20).
• Mean Absolute Deviation (MD): Mean of absolute price deviation of the asset in a time period.
• Constant (0.015)

How Commodity Channel Index indicator works

Usage 1: Entry of bullish trend (>+100 breakout)

A CCI move above +100 suggests upside momentum and at this point we are probably in the early stages of a strong uptrend as opposed to just an overbought indicator. This is where traders look for long entries, confirmed with volume or alignment of the moving average.

Usage 2: Enter / Exit a Bearish Trend (Breakdown -100)

When the reading drops below -100, it shows strong selling pressure and a fresh acceleration of the downtrend. For long positions, this acts as an exit trigger and also an entry signal for short trades

Trend continuation – (Gold Future - MCX: August 2025 – January 2026):

After a steep rebound on 25-June-2025, the CCI moved above +100, suggesting strong buying momentum. During the multi-month rally to new highs, we saw CCI providing consistent support above zero and pushing well into +100 on each expansion leg, providing confirmation of excellent trend strength.

Usage 3: Overbought & Oversold Mean Reversion

For a range-bound market, above +100 indicates overbought conditions (buyers are too far ahead of supply), while below -100 indicates oversold territory (supply is exhausted).

Usage 4: Momentum Divergence

A divergence is when price action makes a higher high or lower low that has not yet been confirmed by the CCI oscillator. This shows that there is no more momentum, and this is usually followed by a steep reversal.

Gold Future - MCX (Dec 2019 — Aug 2020): Bearish Divergence

Starting from December 2019, in the weekly time frame, MCX Gold Future made higher highs till 56,000 before August 2020. On the flip side, lower highs were made by CCI to deliver a solid bearish divergence.

Conclusion

Commodity Channel Index (CCI) is still a powerful technical indicator that can be used to capture cyclical momentum, confirm breakouts and identify potential reversals through divergences.

The CCI is most helpful to the trader when used objectively with price action, volume confirmation and sound risk management, allowing for the perfect combination of information to help traders tackle both trending and range-based markets.
