Weird : Expert loaded successfully but prints nothing

forexgenuine 2013.08.08 08:59

In Expert window I only get

"Print Tick EURUSD,M1: loaded successfully"

nothing more whereas I did ask to print every tick. There's no error.

I have no indicator in chart just this expert, no other charts open.

int start()
  {
         
         
         int i;
         
         string symbol;
         int period;
         
         symbol = "EURUSD";
         period = 1;
         
         i = 0;
         
         double Open_i = iOpen(symbol,period,i);
         double High_i = iHigh(symbol,period,i);
         double Low_i = iLow(symbol,period,i);
         double Close_i = iClose(symbol,period,i);
         double Volume_i = iVolume(symbol,period,i);
         
         
         string quote;
         quote = DoubleToStr(Open_i,5) + " " + DoubleToStr(High_i,5) + " " + DoubleToStr(Low_i,5) + " "  + DoubleToStr(Close_i,5);
         Print("Quote : ", quote );
         
   
   return(0);
  }
