Commodity channel index (CCI)
How far the price is from its average, in units of its typical deviation.
Formula
CCI = (TP − SMA(TP)) ÷ (0.015 × mean absolute deviation), TP = (High + Low + Close) ÷ 3
How to read it
Above +100 strong or overbought, below −100 weak or oversold; about 70–80% of readings fall between them.
How to use it
Spots new trends (a push above +100) and stretched moves to fade inside a range.
