Prevent UserDrawnDrawings to be copied when chart is duplicated

Hi, Is there some way to prevent a drawing that is drawn from a study to not be replicated when a chart is duplicated? The thing is that the UserDrawnDrawing that originated from the study will be present twice in the new chart, one from the duplication and another one from the study load itself. Thanks. Frederik |

Refer to the following: Using Drawing Tools From an Advanced Custom Study: s_UseTool::AllowCopyToOtherCharts For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Hi John, That is not what I meant. The Tool.AllowCopyToOtherCharts = 0; is the default, is a different functionality, and this does not prevent a drawing to be duplicated when a chart is duplicated. When example study is loaded on a chart. And this chart is subsequently duplicated, you will see two rectangle highlight drawings are being drawn on that new chart. One is from the duplication and another one from the study calculation. Would be great if this can be prevented and only the one from the study to be drawn. Thanks for your time. Frederik Example code: SCSFExport scsf_UseToolExampleRectangleHighlight(SCStudyInterfaceRef sc) { // Draw a rectangle highlight // Set configuration variables if (sc.SetDefaults) { sc.GraphName = "UseTool Example: Rectangle Highlight"; sc.GraphRegion = 0; sc.AutoLoop = 0; //No automatic looping return; } int& r_LineNumber = sc.GetPersistentInt(1); if (sc.LastCallToFunction){ if (sc.UserDrawnChartDrawingExists(sc.ChartNumber,r_LineNumber) > 0){ sc.DeleteUserDrawnACSDrawing(sc.ChartNumber, r_LineNumber); } return; } // Do data processing int BarIndex = 0; s_UseTool Tool; //Tool.ChartNumber = sc.ChartNumber; Tool.DrawingType = DRAWING_RECTANGLEHIGHLIGHT; if (r_LineNumber != 0) Tool.LineNumber = r_LineNumber; // Update BarIndex to 30 bars from the end BarIndex = max(sc.ArraySize - 25, 0); Tool.BeginDateTime = sc.BaseDateTimeIn[BarIndex]; BarIndex = max(sc.ArraySize - 15, 0); Tool.EndDateTime = sc.BaseDateTimeIn[BarIndex]; Tool.BeginValue = sc.GetHighest(sc.Low, BarIndex, 10); Tool.EndValue = sc.GetLowest(sc.Low, BarIndex, 10); Tool.Color = RGB(255, 0, 0); // Red Tool.LineWidth = 1; //To see the outline this must be 1 or greater. Tool.SecondaryColor = RGB(0, 255, 0); Tool.TransparencyLevel = 50; Tool.AddMethod = UTAM_ADD_OR_ADJUST; Tool.AllowSaveToChartbook = 0; Tool.AddAsUserDrawnDrawing = 1; Tool.AllowCopyToOtherCharts = 0; sc.UseTool(Tool); r_LineNumber = Tool.LineNumber;//Remember line number which has been automatically set } |

Sorry, you are correct. We were not thinking of the duplicate chart functionality. The option available is to not make the drawing a User Drawn Drawing. Otherwise, you would have to check for the existence of the drawing an then not draw it again.

What you suggest will not work. There is no way to distinguish between a user added drawing and a User Drawn Drawing made by a study, there is no way to distinguish by which study a drawing was made, making the check impossible. The simplest is to exclude duplicating User Drawn Drawings made by a study when a chart is duplicated.

We will implement a solution to this including being able to determine if a Chart Drawing was added by a custom study.
