OnChartEvent() ... does not work in Indicator but in strategy do.

[PetrMatuska]

dear, can OnChartEvent() work in indicator? ( according to manual yes) but this code as indicator doesn't work. Do you know why, please?

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

//| ChartEvent function                                              |

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

void OnChartEvent(const int id,

                  const long &lparam,

                  const double &dparam,

                  const string &sparam)

  {

//---

   //---

   ResetLastError();

   RefreshRates();

   //--

   static bool keyPressed=false;

//--- this is an Event of a keystroke

   if(id==CHARTEVENT_KEYDOWN)

     {

      if(lparam==KEY_PLUS || lparam==KEY_MINUS)

        {

         if(!keyPressed) keyPressed=true;

         else keyPressed=false;

        }

      //--

      switch(int(lparam)) 

        { 

          case KEY_PLUS:  

                 {

                    //.... etc

                    MessageBox("PLUS");

                 }

               break;

          case KEY_MINUS: 

                 {

                    //.... etc

                    MessageBox ("MINUS");

                 }

               break;

        }

     }

  }
