Commodity Channel Index (CCI)

Developed by Donald Lambert in 1980 for commodity markets, CCI has become widely used across all asset classes including crypto. It is calculated by measuring the difference between the current typical price (average of high, low, and close) and its simple moving average, then dividing by the mean absolute deviation and scaling by a constant (0.015) to ensure approximately 75% of values fall between -100 and +100.

CCI generates three types of signals: overbought/oversold (readings beyond +100/-100), zero-line crossovers (crossing above zero is bullish, below is bearish), and divergences. Unlike RSI which is bounded at 0-100, CCI has no upper or lower limit, which makes extreme readings (above +200 or below -200) particularly significant for identifying euphoria or panic.

According to a 2020 analysis by StockCharts.com, CCI divergence on the weekly timeframe correctly preceded intermediate-term reversals in approximately 58% of cases across major indices. In crypto, CCI's unbounded nature makes it useful for measuring the intensity of parabolic moves — Bitcoin frequently registers CCI readings above +300 during blow-off tops and below -300 during capitulation events.

CCI is especially effective when used alongside other indicators rather than in isolation. A CCI reading above +100 combined with a breakout above resistance on elevated volume provides stronger confirmation than any single signal alone. The indicator's sensitivity can be adjusted by changing the lookback period: shorter periods (10) produce more signals with more noise, while longer periods (30) produce fewer but more reliable signals.
