As a test for what I want to do, I tried to create a simple study that would draw a line. The start point is inputted by the user in the study settings. After that, the line is meant to be dynamically drawn/redrawn to the highest high following the start bar. The code compiled but is not drawing anything. This is my first attempt at ACSIL. Any help/advice would be appreciated. Here's the code:


#include "sierrachart.h"

SCDLLName("DLT DLL")

SCSFExport scsf_DynamicLineTest(SCStudyGraphRef sc)
{

  SCInputRef SwingLowBar = sc.Input[0];

  if (sc.SetDefaults)
  {
    sc.GraphName = "DLT";
    sc.GraphRegion = 0;
    
    sc.FreeDLL = 1;

    sc.AutoLoop = 1;
        
    SwingLowBar.Name = "SwingLowBar";
    SwingLowBar.SetInt(0);
    
    return;
  }
  
  
  int StartBar;
  int EndBar;
  float StartPrice;
  float EndPrice;
  
  StartBar = SwingLowBar.GetInt();
  
  if (sc.Index < StartBar) return;
  
  if (sc.Index == StartBar)
    {
    StartPrice = sc.Low[sc.Index];
    EndPrice = sc.High[sc.Index];
    }
  
  if (sc.Index > StartBar)
  {

  EndPrice = max(sc.High[sc.Index], EndPrice);
  
    if (EndPrice == sc.High[sc.Index])
    {
      EndBar = sc.Index;
      
      const int UniqueLineNumber =57683545;
  
      if (sc.LastCallToFunction)
      {
      sc.DeleteUserDrawnACSDrawing(sc.ChartNumber, UniqueLineNumber + 21);
      return;
      }
      
      s_UseTool Tool;
  
  
      Tool.Clear();
      Tool.ChartNumber = sc.ChartNumber;
      Tool.DrawingType = DRAWING_LINE;
      Tool.LineNumber = UniqueLineNumber+1;
      Tool.BeginIndex = StartBar;
      Tool.EndIndex = EndBar;
      Tool.BeginValue = StartPrice;
      Tool.EndValue = EndPrice;
      Tool.Color = RGB(255,0,255);
      Tool.AddMethod = UTAM_ADD_OR_ADJUST;
      
      sc.UseTool(Tool);
    }
  }
}
