Add value variable to Alert popup

[fly7680]

Hello everyone, I should add in the Alert pop-up, the value of a variable double , but as I wrote the code is not good.

#include <stdlib.mqh>
#include <stderror.mqh>


//--- indicator settings
#property indicator_chart_window
#property indicator_buffers 2

#property indicator_type1 DRAW_ARROW
#property indicator_width1 1
#property indicator_color1 White
#property indicator_label1 ""

#property indicator_type2 DRAW_ARROW
#property indicator_width2 1
#property indicator_color2 White
#property indicator_label2 ""



//--- indicator buffers
double Buffer1[];
double Buffer2[];

extern int    Periodo       = 2;
extern double RSI_max       = 95;
extern double RSI_min       = 5;
extern double DistanzaIcona = 1;
extern int    Percent       = 30;
extern bool   Audible_Alerts = true;
datetime time_alert; //used when sending alert
double   myPoint;    //initialized in OnInit

void myAlert(string type, string message)
  {
   if(type == "print")
      Print(message);
   else if(type == "error")
     {
      Print(type+" | V2.0 @ "+Symbol()+","+Period()+" | "+message);
     }
   else if(type == "order")
     {
     }
   else if(type == "modify")
     {
     }
   else if(type == "indicator")
     {
      if(Audible_Alerts) Alert(type+" | V2.0 @ "+Symbol()+","+Period()+" | "+message);
     }
  }

fly7680: I should add in the Alert pop-up, the value of a variable double , but as I wrote the code is not good. void myAlert(string type, string message){	No it's not. So fix it. learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem.

Make sure that you pass the correct number of parameters to a function.

Use DoubleToStr() to convert a double to a string.
