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" SCDLLName("HA_colors") SCSFExport scsf_MyStudyHA(SCStudyInterfaceRef sc) {   //logging object   SCString msg;   //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);     //sc.GraphDrawType = GDT_CANDLESTICK;     sc.GraphRegion = 1;     sc.ValueFormat = VALUEFORMAT_INHERITED;              sc.AutoLoop = 1;     return;   }    //sc.GetChartArray()   //get main price graph open and close   SCFloatArray ORef;   SCFloatArray CRef;   sc.GetChartArray(1, SC_OPEN, ORef);   sc.GetChartArray(1, SC_LAST, CRef);   int oSize = ORef.GetArraySize();   int cSize = CRef.GetArraySize();   //SCFloatArray T3Ref;   //Study ID as obtained via Input or Study Int# shown in the Studies view ID:16 T3-8, Subgraph array starts with 0 -SG1 has index 0   //sc.GetStudyArrayUsingID(i_T3.GetStudyID(), 0, T3Ref);   //sc.GetStudyArrayUsingID(16, 0, T3Ref);   SCFloatArray T35Ref; //13   SCFloatArray T38Ref; //16   sc.GetStudyArrayUsingID(13, 0, T35Ref); //T3-5   sc.GetStudyArrayUsingID(16, 0, T38Ref); //T3-8   SCFloatArray T35aRef; //40   SCFloatArray T38aRef; //39   sc.GetStudyArrayUsingID(40, 0, T35aRef); //angle of T3-5   sc.GetStudyArrayUsingID(39, 0, T38aRef); //angle of T3-8   //get a sudy's supbgraph's values - all values show in log as expected   if (sc.Index == oSize - 1) {     msg.Format("Open=%f, Close=%f, T35=%f, T35a=%f, T38=%f, T38a=%f", ORef[sc.Index], CRef[sc.Index], T35Ref[sc.Index], T35aRef[sc.Index], T38Ref[sc.Index], T38aRef[sc.Index]);     sc.AddMessageToLog(msg, 1);   }   //This part does not work yet..   //process coloring of Heikin-Ashi bars based on T3-5 and T3-8 cross and their angles being both positive or negative   if (sc.Index <= oSize - 1)   {     if(ORef[sc.Index] > CRef[sc.Index]) //open > close     {       if (T35Ref[sc.Index] > T38Ref[sc.Index] && T35aRef[sc.Index] > 1 && T38aRef[sc.Index] > 1)       {         sc.GraphDrawType = GDT_CANDLESTICK;         Subgraph_Open.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_Open.PrimaryColor = RGB(0, 255, 0);         Subgraph_Last.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_Last.PrimaryColor = RGB(0, 255, 0);         Subgraph_High.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_High.PrimaryColor = RGB(0, 255, 0);         Subgraph_Low.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_Low.PrimaryColor = RGB(0, 255, 0);       }       else       {         sc.GraphDrawType = GDT_CANDLESTICK_HOLLOW;         Subgraph_Open.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_Open.PrimaryColor = RGB(0, 255, 0);         Subgraph_Last.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_Last.PrimaryColor = RGB(0, 255, 0);         Subgraph_High.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_High.PrimaryColor = RGB(0, 255, 0);         Subgraph_Low.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_Low.PrimaryColor = RGB(0, 255, 0);       }                 }     else if (ORef[sc.Index] <= CRef[sc.Index]) // open <= close     {       if (T35Ref[sc.Index] < T38Ref[sc.Index] && T35aRef[sc.Index] < -1 && T38aRef[sc.Index] < -1)       {         sc.GraphDrawType = GDT_CANDLESTICK;         Subgraph_Open.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_Open.PrimaryColor = RGB(255, 0, 0);         Subgraph_Last.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_Last.PrimaryColor = RGB(255, 0, 0);         Subgraph_High.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_High.PrimaryColor = RGB(255, 0, 0);         Subgraph_Low.DrawStyle = DRAWSTYLE_COLOR_BAR;         Subgraph_Low.PrimaryColor = RGB(255, 0, 0);       } else       {         sc.GraphDrawType = GDT_CANDLESTICK_HOLLOW;         Subgraph_Open.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_Open.PrimaryColor = RGB(255, 0, 0);         Subgraph_Last.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_Last.PrimaryColor = RGB(255, 0, 0);         Subgraph_High.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_High.PrimaryColor = RGB(255, 0, 0);         Subgraph_Low.DrawStyle = DRAWSTYLE_COLOR_BAR_HOLLOW;         Subgraph_Low.PrimaryColor = RGB(255, 0, 0);       }     }        }       }

OK, I think I have figured this out. It was not very easy or straightforward for me - so I hope this will make it easier for you. See the attached code..
