Thank you, the values there are from a file and one time, but my task is spread out over time.

Record the current price and time at the beginning of each day for 30 minutes, every 120 seconds.

Do not overwrite previous entries.


Start writing your code and what doesn't work, we'll take it apart.

So what's there to write? Take any day and read the opening price of even or odd minutes PERIOD_M1...

This is what I wrote once. Use OnTimer instead of OnTick.

#property strict
enum Локаль   // Десятичный разделитель для отображения в Excel
{
  Точка,
  Запятая
};
extern Локаль   RUS = Запятая; // Для русской локализации запятую

string ИмяФайла;          // Имя файла на диске


void OnInit()
{
  ИмяФайла=Symbol()+".txt";
}


void OnTick()
{
   string Текст, Строка;

   // Открытие или создание файла и перемещение указателя в конец
   int Файл = FileOpen(ИмяФайла, FILE_CSV | FILE_READ | FILE_WRITE, " ");
   if(Файл == -1)
   {
      Alert("Ошибка при открытии файла ", ИмяФайла);
      return;
   }
   FileSeek(Файл, 0, SEEK_END);

   // Если новый файл записать строку заголовков колонок
   if(FileSize(Файл)==0)FileWrite(Файл, "           Время   ASK     BID");

   // Сбор информации и запись в файл
   FileWrite(Файл,
             TimeToStr(Time[0]),
             dstr(Ask),
             dstr(Bid) );
   FileClose(Файл);
   Файл = 0;                 // Заметая следы обнулим указатель
}


// Преобразование числа double в строку с запятой или точкой в соответствии с локализацией
string dstr(double Цена)
{
  if(!RUS) return DoubleToStr(Цена, Digits);
  return StringSetChar(DoubleToStr(Цена, Digits), StringFind(DoubleToStr(Цена, Digits), "."), ',');
}

STARIJ:

Here's something I used to write. Use OnTimer instead of OnTick.

Thanks

 
Hello. Can you please tell me ifafter activatingthe virtual server it is possible to close the mt4 site? Will the virtual server work or how does it work?

This is a problem with Excell. Put a dot instead of a comma as the separator between integer part and fractional part in the settings and it will show correctly.

Writes and how to make it write every 120 seconds within 30 minutes of the bar opening?

 
Good day! Please help me to improve copier code. The problem is the following: EA (Slave) prints the message about no access to the file, no matter what I do... What's wrong?

Note to you.

EventSetTimer

Does it not work in the scripts?
