Can anyone help with ACSIL code to calculate the duration of the current price bar in seconds? I'm using range bars. Thanks in advance, Mike

Take a look at sc.BaseDataEndDateTime and SCDateTimeSpan (in scdatetime.h). ACSIL Interface Members - Variables and Arrays: sc.BaseDataEndDateTime[] There is also the SCDateTime member function GetTimeInSeconds, so you could compare the start time in seconds vs. end time in seconds. Working with the SCDateTime Variables and Values: GetTimeInSeconds() |

Here is how I did it after stealing some code here and there. :) Thanks. //Set the configuration variables and defaults. SCSubgraphRef BarSeconds = sc.Subgraph[0]; if (sc.SetDefaults) { //Set the configuration and defaults sc.GraphName = "Bar Duration In Seconds; sc.GraphRegion = 1; //Not Main graph region sc.AutoLoop = 1; sc.ValueFormat = 0; //Define the Subgraphs BarSeconds.Name = "Bar Seconds"; BarSeconds.DrawStyle = DRAWSTYLE_BAR; BarSeconds.LineWidth = 2; BarSeconds.PrimaryColor = RGB(128,128,128); return; } SCDateTimeMS BarEndDateTime = sc.GetEndingDateTimeForBarIndex(sc.Index); SCDateTimeMS ElapsedTime = static_cast<float>((BarEndDateTime - sc.BaseDateTimeIn[sc.Index] + SCDateTime::MICROSECONDS(1)).GetAsDouble()); BarSeconds[sc.Index] = ElapsedTime.GetTimeInSeconds(); Date Time Of Last Edit: 2022-12-31 18:58:30

To use in your own study // Calculate the duration of the last closed bar in seconds
SCDateTimeMS BarEndDateTime = sc.GetEndingDateTimeForBarIndex(sc.Index - 1); SCDateTimeMS BarStartDateTime = sc.BaseDateTimeIn[sc.Index - 1]; SCDateTimeMS BarDuration = BarEndDateTime - BarStartDateTime + SCDateTime::MICROSECONDS(1); float LastClosedBarSeconds = static_cast<float>(BarDuration.GetTimeInSeconds()); //int64_t LastClosedBarMicroseconds =static_cast<int64_t>(BarDuration.GetAsDouble() * 86400000000.0); // Convert days to microseconds if (LastClosedBarSeconds < 1) {FormulaResult=0;} //if bar is less then a second then ignore |

Sierra chart provides examples using most all of its API. C:\SierraChart\ACS_Source\Studies8.cpp SCSFExport scsf_BarTimeDuration(SCStudyInterfaceRef sc) or ask Grok to fill in details and/or tailor to your specific requirements. You have to decide what you consider bar duration, especially in slow markets BAR BAR BAR |_| // start to end, ignore time between bars |____| // start to start, includes time between bars |____| // end to end, includes time between bars Date Time Of Last Edit: 2025-08-15 16:57:11
