I am not a software engineer. I've been using this structure member for years to retrieve the value of the setting for range bar periods. I would very much appreciate some sample code that I can build on so that my code again works. Thank you.

sc.RangeBarValue

This ACSIL structure member is considered out of date/deprecated. Instead use the sc.GetBarPeriodParameters and sc.SetBarPeriodParameters functions.

sc.GetBarPeriodParameters
sc.GetBarPeriodParameters()

sc.SetBarPeriodParameters
sc.SetBarPeriodParameters()

CCIPredictor Example (from Studies4.cpp ACS folder in your Sierrachart):

Old code

SCSFExport scsf_CCIPredictor(SCStudyInterfaceRef sc)
{
  SCSubgraphRef CCIProjHigh = sc.Subgraph[0];
  SCSubgraphRef CCIProjLow = sc.Subgraph[1];
  SCSubgraphRef CCIOutputHigh = sc.Subgraph[2];
  SCSubgraphRef CCIOutputLow = sc.Subgraph[3];


  SCInputRef CCILength = sc.Input[0];

  if (sc.SetDefaults)
  {
    // Set the configuration and defaults

    sc.GraphName = "CCI Predictor";

    sc.AutoLoop = 1;
    sc.GraphRegion = 1;

    CCIProjHigh.Name = "CCI Proj High";
    CCIProjHigh.DrawStyle = DRAWSTYLE_ARROWDOWN;
    CCIProjHigh.PrimaryColor = RGB(255,255,255);
    CCIProjHigh.LineWidth = 3;
    CCIProjHigh.DrawZeros = false;

    CCIProjLow.Name = "CCI Proj Low";
    CCIProjLow.DrawStyle = DRAWSTYLE_ARROWUP;
    CCIProjLow.PrimaryColor = RGB(255,255,255);
    CCIProjLow.LineWidth = 3;
    CCIProjLow.DrawZeros = false;

    CCILength.Name = "CCI Length";
    CCILength.SetInt(14);

    return;
  }


  //CCI High
  CCIProjHigh.Arrays[0][sc.Index] = sc.HLCAvg[sc.Index];

  if (sc.Index == sc.ArraySize - 1 && sc.AreRangeBars())
  {
    float ProjectedRangeHigh=sc.Low[sc.Index]+sc.RangeBarValue;
    CCIProjHigh.Arrays[0][sc.Index] = ( ProjectedRangeHigh + ProjectedRangeHigh +sc.Low[sc.Index])/3;

  }

  sc.CCI(CCIProjHigh.Arrays[0], CCIOutputHigh, sc.Index, CCILength.GetInt(), 0.015f);

  if (sc.Index == sc.ArraySize - 1)
    CCIProjHigh[sc.Index] = CCIOutputHigh[sc.Index];
  else
    CCIProjHigh[sc.Index] = 0;



  //CCI Low
  CCIProjLow.Arrays[0][sc.Index] = sc.HLCAvg[sc.Index];
  if (sc.Index == sc.ArraySize - 1 && sc.AreRangeBars())
  {

Thank you, kindly. After I took a deep breath, I found the code you indicate and updated. Much appreciated!
