Post From: ACSIL - Modify Swing High / Low? Ray instead of Line

Hello everyone,

I would like to use the Swing High Low study, but would like to not end the horizontal lines at a price intersection. Basically use a ray instead of a line. I have tried modifying it over and over, but not had any success. Does anyone have any tips here?

Thanks!

This is the default code of the study:
SCSFExport scsf_SwingHighAndLow(SCStudyInterfaceRef sc)
{
  SCSubgraphRef Subgraph_SwingHigh = sc.Subgraph[0];
  SCSubgraphRef Subgraph_SwingLow = sc.Subgraph[1];
  SCSubgraphRef Subgraph_LineProperties = sc.Subgraph[2];

  SCInputRef Input_ArrowOffsetValue = sc.Input[0];
  SCInputRef Input_Length = sc.Input[1];
  SCInputRef Input_AllowEqualBars = sc.Input[2];
  SCInputRef Input_ExtendSwings = sc.Input[3];

  if (sc.SetDefaults)
  {
    sc.GraphName = "Swing High And Low";

    sc.AutoLoop = true;
    sc.GraphRegion = 0;
    sc.ValueFormat= VALUEFORMAT_INHERITED;

    Subgraph_SwingHigh.Name = "Swing High";
    Subgraph_SwingHigh.DrawStyle = DRAWSTYLE_ARROW_DOWN;
    Subgraph_SwingHigh.PrimaryColor = RGB(0,255,0);
    Subgraph_SwingHigh.DrawZeros = false;
    Subgraph_SwingHigh.PrimaryColor = RGB(255,0,0);
    Subgraph_SwingHigh.LineWidth = 3;

    Subgraph_SwingLow.Name = "Swing Low";
    Subgraph_SwingLow.DrawStyle = DRAWSTYLE_ARROW_UP;
    Subgraph_SwingLow.PrimaryColor = RGB(255,0,255);
    Subgraph_SwingLow.DrawZeros = false;
    Subgraph_SwingLow.LineWidth = 3;
    Subgraph_SwingLow.PrimaryColor = RGB(0,255,0);

    Subgraph_LineProperties.Name = "Line Properties";
    Subgraph_LineProperties.DrawStyle = DRAWSTYLE_SUBGRAPH_NAME_AND_VALUE_LABELS_ONLY;
    Subgraph_LineProperties.LineWidth = 1;
    Subgraph_LineProperties.PrimaryColor = RGB(255, 0, 0);
    Subgraph_LineProperties.SecondaryColor = RGB(0, 255, 0);
    Subgraph_LineProperties.SecondaryColorUsed = true;
    Subgraph_LineProperties.DrawZeros = false;

    Input_ArrowOffsetValue.Name = "Arrow Offset as Percentage";
    Input_ArrowOffsetValue.SetFloat(3);
    
    Input_Length.Name = "Length";
    Input_Length.SetInt(1);
    Input_Length.SetIntLimits(1,MAX_STUDY_LENGTH);
    
    Input_AllowEqualBars.Name = "Allow Equal High/Low Bars";
    Input_AllowEqualBars.SetYesNo(false);

    Input_ExtendSwings.Name = "Extend Swings Until Future Intersection";
    Input_ExtendSwings.SetYesNo(false);

    return;
  }

  int IndexToEvaluate = sc.Index - Input_Length.GetInt();

  if(IndexToEvaluate - Input_Length.GetInt() < 0)
  {
    return;
  }

  sc.EarliestUpdateSubgraphDataArrayIndex = IndexToEvaluate;

  float ArrowOffset=(sc.High[IndexToEvaluate] - sc.Low[IndexToEvaluate] )*(Input_ArrowOffsetValue.GetFloat() * 0.01f);

  Subgraph_SwingHigh[IndexToEvaluate] = 0;
  Subgraph_SwingLow[IndexToEvaluate] = 0;

  // check for Swing High
  if (!Input_AllowEqualBars.GetYesNo())
  {
    if (sc.IsSwingHigh(sc.High, IndexToEvaluate, Input_Length.GetInt()))
      Subgraph_SwingHigh[IndexToEvaluate] = sc.High[IndexToEvaluate] + ArrowOffset;
  }
  else if (IsSwingHighAllowEqual_S( sc, true , IndexToEvaluate, Input_Length.GetInt()))
    Subgraph_SwingHigh[IndexToEvaluate] = sc.High[IndexToEvaluate] + ArrowOffset;

  }
  else if (IsSwingLowAllowEqual_S(sc, true , IndexToEvaluate, Input_Length.GetInt()))
    Subgraph_SwingLow[IndexToEvaluate] = sc.Low[IndexToEvaluate] - ArrowOffset;

  if (Input_ExtendSwings.GetYesNo())
  {
    if (Subgraph_SwingHigh[IndexToEvaluate] != 0)
    {
      sc.AddLineUntilFutureIntersection
      (IndexToEvaluate
        , 1 // LineIDForBar
        , Subgraph_SwingHigh[IndexToEvaluate]
        , Subgraph_LineProperties.PrimaryColor
        , Subgraph_LineProperties.LineWidth
        , Subgraph_LineProperties.LineStyle
        , false
        , false
        , ""
      );
    }
    else
    {
      sc.DeleteLineUntilFutureIntersection(IndexToEvaluate, 1);

  }
