# Commodity Channel Index (CCI)

The Commodity Channel Index (CCI) compares the current mean price with the average mean price over a typical window of 20 periods.

## Configuration Options

• Period: Number of bars to use in the calculations.
• Color Selectors: Colors to use for graph elements.
• Over Zones Enabled: Whether to shade the area between the plot and the horizontal overbought and oversold levels.
• Over Bought: Overbought quantity
• Over Sold: Oversold quantity
• Display Axis Label: Whether to display the most recent value on the Y axis.

## Formula

$CCI = \frac{( P - A )}{( 0.015 * D )}$

where

$\bullet\; P = Pivot = \frac{(High_{n-period} + Low_{n-period} + Close_{current\;close})}{3}$

$\bullet\; High_{n-period} = Highest\;price\;over\;n-periods$

$\bullet\; Low_{n-period} = Lowest\;price\;over\;n-periods$

$\bullet\; Close_{current\;close} = Current\;close\;price$

$\bullet\; A = n\text{-}period\;moving\;average\;of\;the\;pivot\;value\;P$

$\bullet\; D = mean\;deviation\;of\;the\;absolute\;value\;of\;the\;difference\;between\;the\;mean\;price\;and\;the\;moving\;average\;of\;the\;mean\;price, P-A$
