A 1-minute lesson from the MarketPro academy, one of 22 in trading indicators.

Short answer

The Commodity Channel Index (CCI) measures how far current price has deviated from its statistical average over a chosen period, originally designed for commodities but now applied broadly across markets including currencies and indices. Unlike RSI or stochastic, CCI is not bound to a fixed 0-100 range — it can swing well beyond +100 or -100 during strong moves.

How CCI Is Interpreted

Unlike RSI or stochastic, CCI is not bound to a fixed 0-100 range — it can swing well beyond +100 or -100 during strong moves. Readings above +100 are often read as a strong bullish move, and below -100 as a strong bearish move, with values near zero suggesting price is close to its recent statistical average.

Because CCI is unbounded, "extreme" readings are relative to the specific market and period chosen rather than a universal fixed threshold
CCI is frequently used to spot divergence between price and momentum, similar to RSI or MACD, in addition to its overbought/oversold framing
Sharp, sudden CCI swings during low-liquidity periods can be less meaningful than the same reading during normal trading conditions

As with most oscillators, CCI signals are more reliable when combined with trend context — an extreme reading during a strong trend may simply reflect trend strength rather than an imminent reversal. Treating a single CCI extreme as an automatic trading signal without other confirmation tends to produce inconsistent results.
