I need some help with code so that the study value tracks the last price on the main graph. Just like you can do with the countdown timer study. Here's the code. Thanks JDConner SCSFExport scsf_LargeTextDisplayForStudyFromChart(SCStudyInterfaceRef sc) { SCSubgraphRef TextDisplay = sc.Subgraph[0]; SCInputRef HorizontalPosition = sc.Input[0]; SCInputRef VerticalPosition = sc.Input[1]; SCInputRef DisplayInFillSpace = sc.Input[2]; SCInputRef StudySubgraphReference = sc.Input[3]; SCInputRef DisplaySubgraphName = sc.Input[4]; SCInputRef SubgraphOffset = sc.Input[5]; if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Text Display For Study from Chart"; sc.AutoLoop = 0; sc.GraphRegion = 0; TextDisplay.Name = "Text Display"; TextDisplay.LineWidth = 20; TextDisplay.DrawStyle = DRAWSTYLE_CUSTOM_TEXT; TextDisplay.PrimaryColor = RGB(0, 0, 0); //black TextDisplay.SecondaryColor = RGB(128, 255, 255); TextDisplay.SecondaryColorUsed = true; TextDisplay.DisplayNameValueInWindowsFlags = 0; HorizontalPosition.Name = "Horizontal Position From Left (1-150)"; HorizontalPosition.SetInt(20); HorizontalPosition.SetIntLimits(1,150); VerticalPosition.Name = "Vertical Position From Bottom (1-100)"; VerticalPosition.SetInt(90); VerticalPosition.SetIntLimits(1,100); DisplayInFillSpace.Name = "Display in Fill Space"; DisplayInFillSpace.SetYesNo(false); StudySubgraphReference.Name = "Study And Subgraph To Display"; StudySubgraphReference.SetChartStudySubgraphValues(1, 1, 0); DisplaySubgraphName.Name = "Display Subgraph Name"; DisplaySubgraphName.SetYesNo(false); SubgraphOffset.Name = "Subgraph Columns Back"; SubgraphOffset.SetInt(0); sc.TextInputName= "Prefix Text for Display Value"; // During development set this flag to 1, so the DLL can be modified. When development is completed, set it to 0 to improve performance. sc.FreeDLL = false; return; } // Do data processing if (sc.HideStudy)//do nothing if study is hidden return; SCFloatArray StudyReference; //sc.GetStudyArrayFromChartUsingID(StudySubgraphReference.GetChartStudySubgraphValues(), StudyReference); sc.GetStudyArrayFromChartUsingID(StudySubgraphReference.GetChartNumber(), StudySubgraphReference.GetStudyID(), StudySubgraphReference.GetSubgraphIndex(), StudyReference); s_UseTool Tool; Tool.Clear(); // Reset tool structure for our next use. Unnecessary in this case, but good practice. Tool.ChartNumber = sc.ChartNumber; Tool.DrawingType = DRAWING_TEXT; Tool.LineNumber = 79212343+ (sc.StudyGraphInstanceID); if(!DisplayInFillSpace.GetYesNo() && !sc.Input[8].GetYesNo()) Tool.BeginDateTime = HorizontalPosition.GetInt(); else Tool.BeginDateTime = -3; Tool.Region = sc.GraphRegion; Tool.BeginValue = (float)VerticalPosition.GetInt(); Tool.UseRelativeVerticalValues = true; Tool.Color = TextDisplay.PrimaryColor; Tool.FontBackColor = TextDisplay.SecondaryColor; Tool.FontBold = true; SCString ValueText; if (sc.TextInput.GetLength()>0) { ValueText+= sc.TextInput; ValueText += " "; } int ColumnsBack = SubgraphOffset.GetInt(); float StudyValue = StudyReference[StudyReference.GetArraySize() - 1 - ColumnsBack]; if (StudyValue == -FLT_MAX)//Patch for when referencing data from the Numbers Bars Calculated Values study. This value could be used. StudyValue = 0; ValueText +=sc.FormatGraphValue(StudyValue, sc.GetValueFormat()); Tool.Text = ValueText; Tool.FontSize = TextDisplay.LineWidth; Tool.AddMethod = UTAM_ADD_OR_ADJUST; Tool.ReverseTextColor = false; sc.UseTool(Tool); } |
