I am attempting to draw a volume profile starting when an even occurs in my custom study. There are debug statements in my code that show this block is getting run when the event triggers. Config 3 is the VP config I set up and want to use for this study (followed the steps here: Volume By Price Study: Step by Step Instructions to Configure the Draw Volume Profile Tool). Will there be an example study for using DRAW_VOLUME_PROFILE added in the future? My search of the ACS_Source directory didn't find anything. if(event) { s_UseTool Tool; int& r_LineNumber= sc.GetPersistentInt(1); if (r_LineNumber!= 0) Tool.LineNumber = r_LineNumber; Tool.ChartNumber = sc.ChartNumber; Tool.DrawingType = DRAWING_VOLUME_PROFILE; Tool.BeginIndex = sc.Index; // I also tried with BeginDateTime // Tool.BeginDateTime = sc.BaseDateTimeIn[sc.Index]; Tool.Region = 0; Tool.UseToolConfigNum = 3; Tool.AddMethod = UTAM_ADD_OR_ADJUST; sc.UseTool(Tool); r_LineNumber = Tool.LineNumber; } |

To anyone reading this in the future: I ended up using a VbP study and then updating the start date/start time from my custom study. This also allows easier modification than having to update a config, etc. Note that the inputs for date/time are separate for the VbP study (unlike the VWAP study). I had trouble just passing the full SCDateTime (as a double). Using something like this worked: // This is the datetime you want VbP to start at SCDateTime newDateTime {generateEventDateTime()}; // This will be passed to the "Start Date" VbP input int date {newDateTime.GetDate()}; // This will be passed to the "Start Time" VbP input SCDateTime timeOnly {newDateTime.GetTimeAsSCDateTime()}; // Setting the VbP study Start Date input sc.SetChartStudyInputInt(sc.ChartNumber, Input_VbPStudyID.GetStudyID(), 36, date); // Setting the VbP study Start Time input sc.SetChartStudyInputFloat(sc.ChartNumber, Input_VbPStudyID.GetStudyID(), 38, time_only.GetAsDouble()); |
