CCI: Commodity Channel Index

In TTR: Technical Trading Rules

Commodity Channel Index

Description

The Commodity Channel Index (CCI) attempts to identify starting and ending trends.

Usage

CCI(HLC, n = 20, maType, c = 0.015, ...)

Arguments

HLC	Object that is coercible to xts or matrix and contains High-Low-Close prices. If only a univariate series is given, it will be used. See details.
n	Number of periods for moving average.
maType	A function or a string naming the function to be called.
c	Constant to apply to the mean deviation.
...	Other arguments to be passed to the maType function.

Details

CCI relates the current price and the average of price over n periods. The CCI usually falls in a channel of -100 to 100. A basic CCI trading system is: Buy (sell) if CCI rises above 100 (falls below -100) and sell (buy) when it falls below 100 (rises above -100).

CCI is usually calculated using the typical price, but if a univariate series (e.g. Close, Weighted Close, Median Price, etc.) is provided, it will be used instead.

Value

A object of the same class as HLC or a vector (if try.xts fails) containing the CCI values.

Note

If HLC is a High-Low-Close matrix, then typical price will be calculated. If HLC is a vector, then those values will be used instead of the typical price.
