CCI (Commodity Channel Index) · Centro assistenza

CCI measures how far price has strayed from its statistical mean, normalized by mean deviation. Readings above +100 flag unusually strong upside momentum (possible overbought), below −100 the reverse; zero-line crosses are used as trend triggers. Copy the version for your platform.
