Anna Coulling VPA Setting Question

[WestCoastTrader 0]

Hello,

I am just finishing up Anna Coulling book on VPA, and i am working on getting Volume by price setup and there are setting that I am not sure about.

The settings I can change are

Volume Look Back Depth: (Currently set at 70 can be 10-1000)
Number of Bars (Currently set at 100 can be 10-500)
Bar Length Multiplier (Currently set at 50 can be 10-100)
Bar Horizontal Offset (Currently set at 30 can be 0-100 )
Bar Width (Currently set at 2 can be 1-20)

Just curious what settings you guys would use?

Thanks
Michael
