Hello team, my apologies, I just understood better persistent variables and made it work. Just in case someone else wants to know:


SCSFExport scsf_DrawMaxAndMin(SCStudyInterfaceRef sc)
{

  if (sc.SetDefaults)
  { ... }

  float& maximum = sc.GetPersistentFloat(1);
  float& minimum = sc.GetPersistentFloat(2);
  
  if (sc.IsFullRecalculation && sc.Index == 0)
  {
    sc.GetPersistentFloat(1) = 100.0;
    sc.GetPersistentFloat(2) = 100000.0;
  }

  if (sc.Index == sc.ArraySize - 1) // Only calculated for the latest bar
  {
    float currentHigh = sc.BaseDataIn[SC_HIGH][sc.Index];
    float currentLow = sc.BaseDataIn[SC_LOW][sc.Index];

    if (maximum < currentHigh)
      maximum = currentHigh;

    if (minimum > currentLow)
      minimum = currentLow;

    SCString DebugMessage;

    // Log minimum value
    DebugMessage.Format("Minimum=%f", minimum);
    sc.AddMessageToLog(DebugMessage, 0);

    // Log maximum value
    DebugMessage.Format("Maximum=%f", maximum);
    sc.AddMessageToLog(DebugMessage, 0);
  }
}
