Adding Bollinger Bands to a custom indicator

[laoshr]

Hello,
Happy New Year!
I am working on trying to get Bollinger bands (Upper and Lower) to plot inside a custom indicator.

I created the AddPlot
AddPlot(Brushes.Transparent, "Upper VB");
AddPlot(Brushes.Transparent, "Lower VB");

and then I am trying to call on the Bollinger indicator in the OnBarUpdate

protected override void OnBarUpdate()
{

if (ShowVB == true)
{

Values[1][0] = Bollinger(NumStdDev,HiWay).Upper[0];
Plots[0].Brush = (UpperColor);
Values[2][0] = Bollinger(NumStdDev,HiWay).Lower[0];
Plots[0].Brush = (LowerColor);
}
}

The Bands plot but are way off the top and bottom of the chart.
Is there something I'm missing here? I was thinking it would be pretty simple to add.

Thank you for any help with this.
Regards,
James

Good Morning,
I finally got the Bollinger bands to plot but on the last bar of the RTH session they shoot up/down off the chart. I can't figure out why they would do this. If anyone has some input about this behavior it would be greatly appreciated.
Thank you very much for your time.
Regards,
James
