I have a study to draw some graphic elements as user drawn drawings. Study deletes that drawings in "LastCallToFunction" section. Deleting works fine when I remove the study from chart. But when I do: 1. close chartbook (save all - yes) 2. re-open the chartbook I can see drawings from previous session. I attached a simple study to show the issue. If you add this study to a chart and open/close chartbook a couple times, you will see many instances of text. SCSFExport scsf_delete_user_drawing(SCStudyGraphRef sc) { int &ln = sc.PersistVars->i1; if (sc.SetDefaults) { sc.GraphName = "Delete User Drawing Test"; sc.FreeDLL = 1; sc.AutoLoop = 1; sc.GraphRegion = 0; return; } if(sc.Index == 0) { if(ln == 0) { s_UseTool tool; tool.AddAsUserDrawnDrawing = 1; tool.ChartNumber = sc.ChartNumber; tool.DrawingType = DRAWING_TEXT; tool.Region = sc.GraphRegion; tool.Color = COLOR_RED; tool.FontSize = 13; tool.TextAlignment = DT_TOP | DT_LEFT; tool.UseRelativeVerticalValues = 1; tool.BeginDateTime = 2; tool.BeginValue = 98.0f; tool.Text = SCString().Format("I'm Text - %f", (float)sc.LatestDateTimeForLastBar); tool.AddMethod = UTAM_ADD_OR_ADJUST; sc.UseTool(tool); ln = tool.LineNumber; } } if(sc.LastCallToFunction) { if(ln != 0) sc.DeleteUserDrawnACSDrawing(sc.ChartNumber, ln); } } |

You need to save this structure variable to 0 to prevent the drawings from being saved: https://www.sierrachart.com/index.php?page=doc/ACSILDrawingTools.html#AllowSaveToChartbook Sierra Chart Support - Engineering Level Your definitive source for support.
