I am not sure what you mean with "TRUE" market profile,
but built-in market profile volume at price has been GREATLY
improved with 5.14.0 BETA. It includes ability to draw at USER-SPECIFIED
points.
It is as true as the one you have posted. There are no "letter codes",
but they only duplicate the same information that is provided by graphical bars.
Now you can draw them at USER-DEFINED time points.
Excerpt from the read me:
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();
