Hi Support....my custom study no longer compiles in 2098. It shows errors with SCDateTime and looks like the same error for each time it is set. I've looked at the documentation but it is unclear what needs to change. Can you please help? ACSIL Interface Members - Variables and Arrays: sc.BaseDateTimeIn[] -- Starting remote build of Custom Studies Source files: AutoTradeOrderFlowV3.cpp. 64-bit -- 08:33:38 Allow time for the server to compile the files and build the DLL.

I'm still getting compile errors after changing.

Any ideas on how to updates? So confusing! ------------------------- SCDateTime RollingStartDateTime = 0; if (sc.AreTimeSpecificBars() && sc.SecondsPerBar != 0) { RollingStartDateTime = sc.BaseDateTimeIn[Index] + (sc.SecondsPerBar - 1) * SCDateTime::SECONDS(1); RollingStartDateTime -= TimePeriodLength.GetInt() * SCDateTime::MINUTES(1); } --------------------- This is the old code ---------------------- SCDateTime RollingStartDateTime = 0; if (sc.AreTimeSpecificBars() && sc.SecondsPerBar != 0) { RollingStartDateTime = sc.BaseDateTimeIn[Index] + (sc.SecondsPerBar - 1) * SECONDS; RollingStartDateTime -= TimePeriodLength.GetInt() * MINUTES; } Date Time Of Last Edit: 2020-05-06 15:57:21

Any other compile errors?

You rock! This section is the last area I believe. These two lines fail: SCDateTime PriorPeriodStartDateTime = InitialStartDateTime - DaysBack * DAYS; SCDateTime PriorPeriodEndDateTime = PriorPeriodStartDateTime + 1 * DAYS - 1 * SECONDS; It seems SC documentation needs several updates on this topic. Without your help, frankly I would not have been able to update. Thank you! -------------------------- Here is the complete function ----------------------------- void GetIndexForStartofDayPeriodForDaysBack ( SCStudyInterfaceRef sc , const SCDateTime InitialStartDateTime , const int NumDaysToInclude , const bool ExcludeWeekends , const int MinimumRequiredTimePeriodInDayAsPercent , int& r_InitialBarIndex ) { int DaysBack = 0; for (int DaysCount = 1; DaysCount < NumDaysToInclude; ++DaysCount) { for (int Iterations = 10; Iterations > 0; --Iterations) { DaysBack++; SCDateTime PriorPeriodStartDateTime = InitialStartDateTime - DaysBack * DAYS; SCDateTime PriorPeriodEndDateTime = PriorPeriodStartDateTime + 1 * DAYS - 1 * SECONDS; const SCDateTime TradingDayDate = sc.GetTradingDayDate(PriorPeriodStartDateTime); r_InitialBarIndex = sc.GetNearestMatchForSCDateTime(sc.ChartNumber, PriorPeriodStartDateTime); if (ExcludeWeekends && TradingDayDate.IsWeekend()) continue; const int PriorPeriodLastIndex = sc.GetNearestMatchForSCDateTime(sc.ChartNumber, PriorPeriodEndDateTime); const double ActualTimeSpan = sc.CalculateTimeSpanAcrossChartBars ( r_InitialBarIndex , PriorPeriodLastIndex ); //If there is a sufficient amount of data in this time period if (ActualTimeSpan > 1*DAYS * (MinimumRequiredTimePeriodInDayAsPercent * 0.01)) break; } } } Date Time Of Last Edit: 2020-05-06 16:25:44

SCDateTime PriorPeriodStartDateTime=InitialStartDateTime-SCDateTime::DAYS(DaysBack); SCDateTime PriorPeriodEndDateTime=PriorPeriodStartDateTime+SCDateTime::DAYS(1)-SCDateTime::SECONDS(1); |

Yes, those two were the last...compiles now

You will maybe have a problem with this line: if (ActualTimeSpan > 1*DAYS * (MinimumRequiredTimePeriodInDayAsPercent * 0.01)) I'm not sure there.. I would probably use SCDateTime::DAYS(MinimumRequiredTimePeriodInDayAsPercent * 0.01) or command InitialStartDateTime.SubtractDays() //referenced in the header file scdatetime.h what is it inline SCDateTime& SCDateTime::SubtractDays(int Days) { m_dt -= Days*DAYS; return *this; } Good luck ;) *note This part is weird .... I don't know why the developer refers to percentages. I would put a fixed time unit there ... but it doesn't matter ... Date Time Of Last Edit: 2020-05-06 17:03:19

Thank you.. I saw that too but was not sure how best to update it. Oddly, it compiles without an error

We have done some updates to the documentation here related to the changes for SCDateTime: Working with the SCDateTime Variables and Values More updates are needed. Regarding post #10, here is an example of how to do this: const SCDateTime ActualTimeSpan(sc.CalculateTimeSpanAcrossChartBars
(r_InitialBarIndex, PriorPeriodLastIndex)); //If there is a sufficient amount of data in this time period if (ActualTimeSpan > SCDateTime::SECONDS_Fraction(MinimumRequiredTimePeriodInDayAsPercent * 0.01 * SECONDS_PER_DAY)) { break; } Sierra Chart Support - Engineering Level Your definitive source for support.
