Syntax


public static void PriceVolumeDist(this WealthScript obj, int Lookback, Color LineColor, Color FillColor)

public void PriceVolumeDist( int Lookback, System.Color LineColor, System.Color FillColor );

Parameter Description

Lookback	Number of bars used in the distribution
LineColor	Outline color of the distribution bars. For no outline, pass the same color as FillColor
FillColor	Fill color of the distibution bars

Description

A price-volume distribution is the total volume traded in price ranges (or bins) displayed in relative terms as horizontal bars alongside the right chart axis. The price-volume distribution is calculated for the number of bars specified in the Lookback parameter, as described in the example.

Originally created by Robert Sucher and Dion Kurczek.
