ChartXYToTimePrice return error code: 4102

New comment
 

Hello!
My own expert advisor has been running reliably on the mt5 platform for months. Unfortunately, since the last platform update, my expert advisor is not running. After some searching, I found the error:

ChartXYToTimePrice return error code: 4102
ERR_CHART_NO_REPLY - 4102 - Chart does not respond

Please help me find a solution so that my expert advisor can work as before. Thank you in advance!


This sample code generates the error mentioned above (it is not mine):

//+------------------------------------------------------------------+

void OnChartEvent(const int id,

                  const long &lparam,

                  const double &dparam,

                  const string &sparam)

  {

//--- Show the event parameters on the chart

   Comment(__FUNCTION__,": id=",id," lparam=",lparam," dparam=",dparam," sparam=",sparam);

//--- If this is an event of a mouse click on the chart

   if(id==CHARTEVENT_CLICK)

     {

      //--- Prepare variables

      int      x     =(int)lparam;

      int      y     =(int)dparam;

      datetime dt    =0;

      double   price =0;

      int      window=0;

      //--- Convert the X and Y coordinates in terms of date/time

      if(ChartXYToTimePrice(0,x,y,window,dt,price))

        {

         PrintFormat("Window=%d X=%d  Y=%d  =>  Time=%s  Price=%G",window,x,y,TimeToString(dt),price);

         //--- Perform reverse conversion: (X,Y) => (Time,Price)

         if(ChartTimePriceToXY(0,window,dt,price,x,y))

            PrintFormat("Time=%s  Price=%G  =>  X=%d  Y=%d",TimeToString(dt),price,x,y);

         else

            Print("ChartTimePriceToXY return error code: ",GetLastError());

         //--- delete lines

         ObjectDelete(0,"V Line");

         ObjectDelete(0,"H Line");

         //--- create horizontal and vertical lines of the crosshair

         ObjectCreate(0,"H Line",OBJ_HLINE,window,dt,price);

         ObjectCreate(0,"V Line",OBJ_VLINE,window,dt,price);

         ChartRedraw(0);

        }

      else

         Print("ChartXYToTimePrice return error code: ",GetLastError());

      Print("+--------------------------------------------------------------+");

     }

  }//+--

 

The issue resolved itself with a more recent centrally enforced update, so this topic is no longer active.

Thanx!
