CCI (Commodity Channel Index) — what it is and how to use it in trading
Definition
CCI (Commodity Channel Index) is a momentum oscillator measuring how far the current typical price deviates from its moving average over period candles, normalized by the mean absolute deviation. Despite the "commodity" name, it applies equally to any market.
How it works in the builder
The cci operand takes a period parameter (default 20) and returns a number with no fixed upper/lower bound, though in practice most readings fall roughly within -100 to +100.
What it looks like on the chart
Drawn as a separate panel with horizontal levels at +100 and -100 — moving beyond them is read as a strong momentum push, not just narrow overbought/oversold.
Typical use
Typical condition: cci(20) > 100 as a strong-uptrend-momentum filter, or cci(20) crossed_below -100 to trade the start of a strong sell-off.
Common pitfalls
Because CCI is not formally bounded, readings can travel well beyond +-100 on strong moves and stay there for a while — the +-100 level is not a hard reversal boundary, more a threshold for a "notable" momentum push.
