Do i need to Time frame comments in the programs? or it will be automatic?

Cause this programs shows my error.

 
no you don't need it will read current time frame if you not define it. similar with NULL.

Try this indicator code ...

#property indicator_chart_window

int start(){
   string bid = "Bid= "    +  DoubleToStr( Bid, Digits ) + "\n";
   string ask = "Ask= "  +    DoubleToStr( Ask, Digits ) + "\n";
   string range = "Range= " + DoubleToStr( High[1]-Low[1], Digits );
   Comment( bid + ask + range );
   
   return(0);
}
