Михаил :

O zaman, "En İyi Pupua Kodlayıcı - 2015" unvanı için ilk yarışmacı sizsiniz.

P/S Konuyu okuyanlardan rica gülerek koltuktan düşmesin :)

Pekala, siktir git, dört satır kod çözemezsen defol (anlamayı kolaylaştırmak için özellikle iki yerine dört)

Zorluk nedir? 86400 sayısının ne olduğu belli değil mi? Veya 3600?

86400, bir gündeki saniye sayısıdır. 3600 - bir saat içinde.

not. Bu nasıl bir gülüş? Burada ağlamak zorundasın.

Sık kullanılan ve kullanışlı özellikler:

SetStDayTime() işlevi çok hızlı değildi, bu yüzden

Gözden geçirilmiş olanı gönderiyorum (Sergey sayesinde):

 datetime SetStDayTime()
{
   MqlDateTime   dt_str;
   ulong one_day = 86400 ;
   TimeTradeServer ( dt_str );
   int hour = dt_str.hour;
  dt_str.hour = 19 ;
  dt_str.min = 0 ;
  dt_str.sec = 0 ;
   ulong time_start = ulong ( StructToTime ( dt_str ) );
//---   
   switch ( dt_str.day_of_week )
  {
     case 6 :  time_start -= one_day;
             break ;
     case 0 :  time_start -= one_day * 2 ;
             break ;
     case 1 :   if ( hour < 19 ) time_start -= one_day * 3 ;
             break ;
     default : if ( hour < 19 ) time_start -= one_day;
             break ;
  }
   return ( datetime ( time_start ) );
}

özellikler:

OrderSend() fonksiyonunun dönüş kodunda bir onay (TRADE_RETCODE_PLACED ) ve bir sipariş bileti almış olmak,

 if ( OrderSend ( request, result ) )
{
   if ( result.retcode == TRADE_RETCODE_PLACED )
  { 
    ticket = result.order;
  }
}

ve OnTradeTransaction() içindeki OrderSendAsync() işlevi için bu, hiç de öyle olmadığı anlamına gelmez.

sipariş aslında borsada YERLEŞTİRİLMİŞTİR.

Bu nedenle, sipariş durumunun ek bir kontrolü gereklidir (tıpkı siparişteki diğer işlemlerde olduğu gibi).

CheckOrderState() işlevinde bir yazım hatası var.

init_volume == init_volume yerine

init_volume == cur_volume olmalıdır

Bir siparişi değiştirmek veya silmek istiyorsak, sadece var olduğunu bilmemiz gerekir:

ORDER_DATA order_data;
   ulong a_ticket = 12345 ;
//---
   if ( OrderRealSelect( a_ticket, order_data, false ) == SELECT_TRUE )
  {
     //Удаляем или модифицируем ордер ( false - не получаем данные по ордеру)
  }

Silme işleminden sonra siparişle ilgili veri almamız gerekirse, o zaman:

ORDER_DATA order_data;
   ulong a_ticket = 12345 ;
//---
   if ( OrderRealSelect( a_ticket, order_data, true ) == SELECT_FALSE )
  {
    a_ticket = 0 ;
     //Смотрим данные по ордеру в order_data    
  }

Bir hata durumunda:

ORDER_DATA order_data;
   ulong a_ticket = 12345 ;
//---
   if ( OrderRealSelect( a_ticket, order_data, true ) == SELECT_ERROR )
  {
     //Не важно, запрашивали мы данные по ордеру (true) или нет(false) коды ошибки 
     //будут всегда
     switch ( order_data.error_code )
    {
       //.................................
    }    
  }
