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.
