Frequently Asked Questions

ta.cci() returns the Commodity Channel Index, measuring how far price deviates from its statistical mean over length bars, scaled by a constant (0.015).

Common references use +100 and -100 as elevated extremes, with zero as a mean-reversion midpoint. Interpretation depends on volatility and market regime.

CCI divides the source-minus-SMA difference by 0.015 times the mean absolute deviation. The factor belongs in the denominator; it does not multiply the final ratio.
