Are you using 5.14 BETA or higher? Did you check the
readme:
new multiple Volume At Price charts at
user-defined points via new PlotVolumeOverlayA function
PlotVAPOverlayA(
segments, lines = 300, width = 80, color = colorLightGrey, vapstyle = 4);
segmens - is an array which holds 0 and 1 (False/True) values, where 1
indicates starting/ending point of each VAP segment
AmiBroker will draw as many segments as there are '1' in the array. Note that
minimum segment length is 2, so if entire array is filled with 1-s only,
it
won't draw anything. In other words, there must be zeros (at least one) between
1's.
Simplest example:
Plot(C,
"Close", colorBlack, styleCandle );
segments =
IIf( Interval() < inDaily, Day(), Month() ); // draw daily or monthly VAP segments depending on display
interval
segments = segments != Ref( segments , -1 );
PlotVAPOverlayA( segments );
More complex example:
_SECTION_BEGIN("Price");
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g
(%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));
Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() );
_SECTION_END();
_SECTION_BEGIN("VAP");
segments = IIf( Interval() < inDaily, Day(), Month() );
segments = segments !=
Ref( segments ,
-1 );
PlotVAPOverlayA( segments , Param("Lines", 300, 100, 1000, 1 ), Param("Width", 80, 1, 100, 1 ), ParamColor("Color", colorGold ),
ParamToggle("Side", "Left|Right" ) | 2 * ParamToggle("Style", "Fill|Lines", 0) | 4*ParamToggle("Z-order", "On top|Behind", 1 ) );
Plot(segments, "", colorLightGrey,
styleHistogram | styleOwnScale );
_SECTION_END();

The Finag add-in is excellent and provides lots of MP
