connecting TradingCharts ?

Hi Everyone
I’ve transformed lists of strings to be appropriate for TradingChart {{{YYYY, MM, DD}, {O, H, L,C,V}}…} and made some changes with a function for plotting
these data:

ClearAll
strzala[{{xmin_, xmax_}, {ymin_, ymax_}}, {o_, h_, l_, c_}, 
  metoda_] := {Line[{{(xmin + xmax)/2, o}, {(xmin + xmax)/2, c}}], 
  Line[{{{xmin, o}, {(xmin + xmax)/2, o}, {(xmin + xmax)/2, 
      If[o < c, l, h]}}, {{xmax, c}, {(xmin + xmax)/2, 
      c}, {(xmin + xmax)/2, If[o < c, h, l]}}}]}

CandlestickChart[list, Axes -> True, GridLines -> Automatic, 
 AspectRatio -> 0.4, ImageSize -> 440, BarSpacing -> Automatic, 
 TrendStyle -> {Green, Red}, ChartBaseStyle -> AbsoluteThickness[1], 
 ChartElementFunction -> strzala, PlotLabel -> "Moja wersja", 
 BaseStyle -> {FontFamily -> "Helvetica"}]

However, I’d like to add a subplot, which contains date for volume (v) taken from the lists, and it is welded in that way like

TradingChart[list]

. And I do not know how to achieve this.

To make something like this, a good first step would be to make both the plot and the subplot and then to put them together using a GraphicsColumn.

GraphicsColumn will make it easy, but it may be difficult to get things sized correctly. I can imagine that if I were making something similar, I might try writing it from scratch using Graphics primitives so that I had total control over everything.

Thanks for clue . What are these “Graphics primitives” ? Where can i find more about that ?

A good place to start might be this tutorial: http://reference.wolfram.com/mathematica/tutorial/TheStructureOfGraphics.html
