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;
    }
  }
}
