Post From: Subject: Renko bar High/Low showing zero range during Replay (ACSIL, AutoLoop=1)

We did a test of this to ensure there is not something odd occurring, but we are not seeing any issues with this.

Although it should not matter in this case, keep in mind that the actual High and Low are different from the Renko High and Low. Refer to the following:
Renko Bar Charts: Renko Open, High, Low, Close Values

The following is the code we used to test:

[
#include "sierrachart.h"

SCDLLName("Testing")

SCSFExport scsf_SimulationModeState(SCStudyInterfaceRef sc)
{
  // Setup References
  SCSubgraphRef High = sc.Subgraph[0];
  SCSubgraphRef Low = sc.Subgraph[1];
  SCSubgraphRef Diff = sc.Subgraph[2];

  if (sc.SetDefaults)  
  {
    sc.GraphName = "Testing";
    sc.AutoLoop = 1;
    sc.GraphRegion = 0;

    High.Name = "High";
    High.DrawStyle = DRAWSTYLE_LINE;
    High.DrawZeros = true;

    Low.Name = "Low";
    Low.DrawStyle = DRAWSTYLE_LINE;
    Low.DrawZeros = true;

    Diff.Name = "Diff";
    Diff.DrawStyle = DRAWSTYLE_LINE;
    Diff.DrawZeros = true;
    
    return;
  }

  High[sc.Index] = sc.High[sc.Index];
  Low[sc.Index] = sc.Low[sc.Index];
  Diff[sc.Index] = High[sc.Index] - Low[sc.Index];
}
