Is there a similar function that adds a "Horizontal Ray Until Future Intersection" to the close of a study (not a bar) that's in a region other than price? I've tried the drawing function below with "ExtendUntilFutureInterection" but am unsuccessful. Thank you for any suggestions! tool.DrawingType = DRAWING_HORIZONTAL_RAY; SEE THE REST OF MY CODE BELOW: #include "sierrachart.h" SCDLLName("TrendeX_Naked_Closes") SCSFExport scsf_TrendeX_Naked_Closes(SCStudyInterfaceRef sc) { SCInputRef Input_StudySubgraph = sc.Input[0]; if (sc.SetDefaults) { // Set the configuration and defaults. sc.GraphName = "TrendeX Naked Closes"; sc.StudyDescription = "Plots a horizontal ray line at swing high and swing low pivots."; Input_StudySubgraph.Name = "Input Study and Subgraph"; Input_StudySubgraph.SetStudySubgraphValues(1, 0); // Defaults to study 1, subgraph 0 sc.AutoLoop = 1; sc.GraphRegion = 1; sc.ValueFormat = VALUEFORMAT_INHERITED; return; } SCFloatArray StudySubgraphArray; sc.GetStudyArrayUsingID(Input_StudySubgraph.GetStudyID(), Input_StudySubgraph.GetSubgraphIndex(), StudySubgraphArray); for (int Index = sc.UpdateStartIndex; Index < sc.ArraySize; ++Index) { if(Index < 2) continue; // Skip the first two bars // High pivot (3-bar reversal to the upside) if (StudySubgraphArray[Index - 1] > StudySubgraphArray[Index - 2] && StudySubgraphArray[Index - 1] > StudySubgraphArray[Index]) { s_UseTool tool; tool.Clear(); tool.ChartNumber = sc.ChartNumber; tool.DrawingType = DRAWING_HORIZONTAL_RAY; tool.BeginIndex = Index - 1; tool.BeginValue = StudySubgraphArray[Index - 1]; tool.Region = sc.GraphRegion; tool.Color = RGB(0, 255, 0); // Green tool.LineWidth = 2; tool.AddMethod = UTAM_ADD_ALWAYS; tool.ExtendUntilFutureIntersection = 1; sc.UseTool(tool); } // Low pivot (3-bar reversal to the downside) if (StudySubgraphArray[Index - 1] < StudySubgraphArray[Index - 2] && StudySubgraphArray[Index - 1] < StudySubgraphArray[Index]) { s_UseTool tool; tool.Clear(); tool.ChartNumber = sc.ChartNumber; tool.DrawingType = DRAWING_HORIZONTAL_RAY; tool.BeginIndex = Index - 1; tool.BeginValue = StudySubgraphArray[Index - 1]; tool.Region = sc.GraphRegion; tool.Color = RGB(255, 0, 0); // Red tool.LineWidth = 2; tool.AddMethod = UTAM_ADD_ALWAYS; tool.ExtendUntilFutureIntersection = 1; sc.UseTool(tool); } } } |

The Horizontal Ray drawing type by definition extends to the end of the chart. If you want a line that ends when intersected, start with DRAWING_HORIZONTAL_RAY, then when your study detects an intersection change the DrawingType to DRAWING_HORIZONTAL_LINE_NON_EXTENDED and set the end index to the bar where the intersection occurs.

Hey thanks, Brad for the tip!!! As you can see, I've added it to my code below but for some reason, this thing won't compile. Am I missing something here? The remote build did not succeed. Result: TrendeX_Naked_Closes.cpp: In function 'void scsf_TrendeX_Naked_Closes(SCStudyInterfaceRef)': TrendeX_Naked_Closes.cpp:67:84: error: too many arguments to function 67 | if (sc.ChartDrawingExists(sc.ChartNumber, DRAWING_HORIZONTAL_RAY, Index - 1)) | ^ -- End of Build -- 15:26:52 #include "sierrachart.h" SCDLLName("TrendeX_Naked_Closes") SCSFExport scsf_TrendeX_Naked_Closes(SCStudyInterfaceRef sc) { SCInputRef Input_StudySubgraph = sc.Input[0]; if (sc.SetDefaults) { // Set the configuration and defaults. sc.GraphName = "TrendeX Naked Closes"; sc.StudyDescription = "Plots a horizontal ray line at swing high and swing low pivots."; Input_StudySubgraph.Name = "Input Study and Subgraph"; Input_StudySubgraph.SetStudySubgraphValues(1, 0); // Defaults to study 1, subgraph 0 sc.AutoLoop = 1; sc.GraphRegion = 1; sc.ValueFormat = VALUEFORMAT_INHERITED; return; } SCFloatArray StudySubgraphArray; sc.GetStudyArrayUsingID(Input_StudySubgraph.GetStudyID(), Input_StudySubgraph.GetSubgraphIndex(), StudySubgraphArray); for (int Index = sc.UpdateStartIndex; Index < sc.ArraySize; ++Index) { if (Index < 2) continue; // Skip the first two bars // High pivot (3-bar reversal to the upside) if (StudySubgraphArray[Index - 1] > StudySubgraphArray[Index - 2] && StudySubgraphArray[Index - 1] > StudySubgraphArray[Index]) { s_UseTool tool; tool.Clear(); tool.ChartNumber = sc.ChartNumber; tool.DrawingType = DRAWING_HORIZONTAL_RAY; tool.BeginIndex = Index - 1; tool.BeginValue = StudySubgraphArray[Index - 1]; tool.Region = sc.GraphRegion; tool.Color = RGB(0, 255, 0); // Green tool.LineWidth = 2; tool.AddMethod = UTAM_ADD_ALWAYS; sc.UseTool(tool); } // Low pivot (3-bar reversal to the downside) if (StudySubgraphArray[Index - 1] < StudySubgraphArray[Index - 2] && StudySubgraphArray[Index - 1] < StudySubgraphArray[Index]) { s_UseTool tool; tool.Clear(); tool.ChartNumber = sc.ChartNumber; tool.DrawingType = DRAWING_HORIZONTAL_RAY; tool.BeginIndex = Index - 1; tool.BeginValue = StudySubgraphArray[Index - 1]; tool.Region = sc.GraphRegion; tool.Color = RGB(255, 0, 0); // Red tool.LineWidth = 2; tool.AddMethod = UTAM_ADD_ALWAYS; sc.UseTool(tool); } if (sc.ChartDrawingExists(sc.ChartNumber, DRAWING_HORIZONTAL_RAY, Index - 1)) { s_UseTool tool; tool.Clear(); tool.ChartNumber = sc.ChartNumber; tool.DrawingType = DRAWING_HORIZONTAL_LINE_NON_EXTENDED; tool.BeginIndex = Index - 1; tool.BeginValue = StudySubgraphArray[Index - 1]; tool.Color = RGB(0, 0, 255); // Blue tool.LineWidth = 2; tool.AddMethod = UTAM_ADD_OR_ADJUST; sc.UseTool(tool); } } } Date Time Of Last Edit: 2023-06-29 19:09:10

The error says you are using too many parameters in your function call. However, I think you will want to use sc.UserDrawnChartDrawingExists.
