Don,
Here is the code that I use to plot a variable moving average of the volume
based on what time frame I am in.
_SECTION_BEGIN("Volume");
Plot( Volume, _DEFAULT_NAME(), IIf( C > Ref(C,-1), ParamColor("Up Color",
colorGreen ), ParamColor("Down Color", colorRed ) ), ParamStyle( "Style",
styleHistogram | styleThick, maskHistogram ) );
_SECTION_END();
_SECTION_BEGIN("OBV");
Plot( OBV(), _DEFAULT_NAME(), ParamColor("Color", colorCycle ),
ParamStyle("Style") );
_SECTION_END();
_SECTION_BEGIN("MA");
MP = IIf( Interval()==inMonthly, 5, IIf( Interval()==inWeekly, 10, 50 ));
Plot( MA( V, MP ), "VMA(" + MP + ")", ParamColor( "Color", colorCycle ),
ParamStyle("Style") );
_SECTION_END();
It is this last section that you are interested in. The way it reads is if
my time frame is Monthly, then use a 5 month period, if I am in a Weekly
chart, then use a 10 week period, if not then I must be in a Daily time
period and use 50 periods.
Or if you just want a fixed 50 period do the following:
_SECTION_BEGIN("MA");
Plot( MA( V, 50 ), "VMA-50", ParamColor( "Color", colorCycle ),
ParamStyle("Style") );
_SECTION_END();

PS I had a lot of help from folks here in the forum to get this to work
correctly (and my brain on the right track, lol) Graham and many others are
to be thanked.

Subject: [amibroker] MA Volume on main price chart
Hi,
My main price chart has a volume histogram. I want to plot a moving
average of the volume such that it plots against the volume histogram
so that I can see which bars are above/below average vol. I cant get
it to work, possibly because vol has styleownscale set so it plots
like a moving average of the price. I have tried it with and without
styleownscale.
Could anyone kindly advise what I am doing wrong? Many thanks in
advance.
Regards, Don.
