Okay, I figured it out.
After a little digging in the help file - Yes the answer was in the
help file imagine that. I came across the section that discussed
using the parameter styleownscale and attaching to that it's own
minimum and maximum values for it's own scale.
Since we want two different scales - one for the price and it's moving
averages and another one for the volume and it's moving average, it
made sense that I needed to apply the MA of the volume to the "volume
scale".
Figuring out how to specify that particular scale was the issue. The
trick is in the little piece of code - "styleOwnScale, 0 , Maximum"
So here is the revised section of code for the "Volume":
_SECTION_BEGIN("Volume");
Maximum = LastValue( Highest( Volume ) );
VolPer = Param("Vol MA Per", 100, 2, 200, 1 );
Plot( MA( Volume, VolPer ), "MA volume", colorRed, styleLine |
styleOwnScale, 0 , Maximum );
Plot( Volume, _DEFAULT_NAME(), ParamColor("Color", colorBlue ),
styleNoTitle | styleHistogram | styleOwnScale, 0 , Maximum );
_SECTION_END();
