2 Buffer icustom ()

[fly7680]

Hello to all.

I would like to bring up a ball, when the Buffer Histogram purple and  Buffer line are not overlapped. the code written by me no errors.

#resource "\\Indicators\\price_speed_and_acceleration.ex4"

//--- indicator settings
#property indicator_chart_window
#property indicator_buffers 1

#property indicator_type1 DRAW_ARROW
#property indicator_width1 1
#property indicator_color1 0xFFAA00
#property indicator_label1 "Buy"

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

datetime time_alert; //used when sending alert
bool Audible_Alerts = true;
double myPoint; //initialized in OnInit

void myAlert(string type, string message)
  {
   if(type == "print")
      Print(message);
   else if(type == "error")
     {
      Print(type+" | Base1 @ "+Symbol()+","+Period()+" | "+message);
     }
   else if(type == "order")
     {
     }
   else if(type == "modify")
     {
     }
   else if(type == "indicator")
     {
      if(Audible_Alerts) Alert(type+" | Base1 @ "+Symbol()+","+Period()+" | "+message);
     }
  }
