Can you please show me a working example of 4066 checking?

I have several problems with the update of missing history data but NEVER got the 4066 (with GetLastError), I tried many places (in the code).

  int GLError = 0;



      GLError = 4066;
      while(GLError == 4066)
         {
         iOpen("AUDCAD",15,0);
         iHigh("AUDCAD",15,0);
         iLow("AUDCAD",15,0);
         iClose("AUDCAD",15,0);
         GLError = GetLastError();
         if(GLError == 4066) Sleep(15000);
         }

  1. You won't get 4066 unless you shut down the terminal and delete the history files.
  2. Instead of using ACR you can use iTime() same result
       ArrayCopyRates(m1.acr, market.pair, PERIOD_M1);          // I'm in an OnInit.
   //}
}  // OnInitAnalyze
:
   if(m1.acr[0][ACR_TIME] == 0.){                         // Verify M1 data.
      int      gle   = GetLastError();
      if (gle != ERR_HISTORY_WILL_UPDATED){  DisableTrading("No M1 history: "
                                                + GetLastError());   return;  }
      Print("Updating history for M1 chart");
      Sleep(15000);  RefreshRates();
      if(m1.acr[iCB][ACR_TIME] == 0.){
         DisableTrading("Updating history for Minute chart failed: "
                                                + GetLastError());   return;  }
      Print("Updating history for Minute chart Succeeded");
   }  // M1 data
