XAverage (Function)

The XAverage series function is an exponentially weighted moving average of the prices of the last length bars.

Syntax

XAverage(Price, Length)

Returns (Double)

A numeric value containing the exponential average over a specified number of bars.

Parameters

Name	Type	Description
Price	Numeric	Specifies which bar value (price, function, or formula) to use.
Length	Numeric	Sets the number of bars to consider.

Remarks

When this moving average is calculated, every bar’s price in the data file will have an effect on the current average. The effects of the first price will never be completely removed, but its weight will continuously shrink as more and more averages are calculated.
