How to Post a Message for Support

Post From: Heikin-Ashi Custom Colors via ASCIL

I'm attempting to custom color of Heikin-Ashi bars based on T3-5 and T3-8 cross and their angles being both positive or negative.
Got it about 50% done but struggling when trying to apply the logic of changing the candlesticks drawing style to DRAWSTYLE_COLOR_BAR_HOLLOW.
Any tips will be appreciate (the code compiles but has no effect on the candles). The desired effect of coloring is shown on the picture.

#include "sierrachart.h"

  //SCInputRef i_T3 = sc.Input[0];
  SCSubgraphRef Subgraph_Open = sc.Subgraph[0]; //OPEN
  SCSubgraphRef Subgraph_High = sc.Subgraph[1]; //HIGH
  SCSubgraphRef Subgraph_Low = sc.Subgraph[2]; //LOW
  SCSubgraphRef Subgraph_Last = sc.Subgraph[3]; // CLOSE
      
  if (sc.SetDefaults)
  {
    // Set the configuration and defaults
    sc.GraphName = "HK_Colors";
    //i_T3.Name = "Select T3 Study on main price graph";
    //i_T3.SetChartStudyValues(sc.ChartNumber, 0);
