这对你来说是新信息吗？

Anton:

我不完全理解为什么不可能绕过这些CPU负载滞后。可能是无能为力，无法做到这一点。

然而，下面是一个干净的测试，显示了MT5中价格数据相关性的问题。我已经提供了带有注释的代码。简而言之，通过SymbolInfoTick/stack 来获取ticks并相互检查。特别是要避免来自不同来源的相同刻度之间的差距和大滞后。

// Демонстрация лагов OnTick и OnBookEvent.

input uint inMinInterval = 1000; // Минимальное время (в мкс.) лага

// Структура тика, которую удобно будет выводить в ArrayPrint.
struct PRICE
{
  double bid;
  double ask;
  
  bool onTick; // true - источник OnTick+SymbolInfoTick, false - источник OnBookEvent+MarketBookGet
  
  ulong Interval; // Временной интервал между соседними записями.
  
  void Set( const double &dBid, const double &dAsk, const bool bTick )
  {
    static ulong PrevTime = ::GetMicrosecondCount();
    const ulong NewTime = ::GetMicrosecondCount();

    this.bid = dBid;
    this.ask = dAsk;
    
    this.onTick = bTick;
    
    this.Interval = NewTime - PrevTime;
    
    PrevTime = NewTime;    
  }
  
  // Записи одинаковые, если обе соответствующие цены совпадают.
  bool operator ==( const PRICE &Price ) const
  {
    return((this.bid == Price.bid) && (this.ask == Price.ask));
  }
};

PRICE Prices[1000]; // Массив для записи тиков из разных источников.
int Amount = 0;     // Количество записанных тиков

// Возвращает bid/ask-цены из стакана.
bool GetCurrentPrices( double &bid, double &ask )
{
  MqlBookInfo Bands[];

  const bool Res = MarketBookGet(_Symbol, Bands);

  if (Res)
    for (int i = ArraySize(Bands) - 2; i >= 0; i--)
      if (Bands[i].type == BOOK_TYPE_SELL)
      {
        ask = Bands[i].price;
        bid = Bands[i + 1].price;
        
        break;
      }
  
  return(Res);
}

// Если bid или ask стакана поменялся - записываем их.
bool SaveNewTick_Book()
{
  static double PrevBid = 0;
  static double PrevAsk = 0;
  
  double bid;
  double ask;
      
  const bool Res = !IsStopped() && GetCurrentPrices(bid, ask) && ((PrevBid != bid) || (PrevAsk != ask));
  
  if (Res)
  {
    PrevBid = bid;
    PrevAsk = ask;
    
    Prices[Amount++].Set(bid, ask, false);
    
    if (Amount == ArraySize(Prices)) // Если достигли конца массива - выходим.
      ExpertRemove();
  }
  
  return(Res);
}

// Записываем bid и ask
bool SaveNewTick_Tick()
{
  MqlTick Tick;
  
  const bool Res = !IsStopped() && SymbolInfoTick(_Symbol, Tick);
  
  if (Res)
  {
    Prices[Amount++].Set(Tick.bid, Tick.ask, true);
    
    if (Amount == ArraySize(Prices)) // Если достигли конца массива - выходим.
      ExpertRemove();
  }
  
  return(Res);
}

// Проверка на наличие багов и задержек.
void Check()
{    
  if (Amount > 3)
  {
    if ((Prices[Amount - 1].onTick == Prices[Amount - 2].onTick) && // Три подряд записи из одного источника - баг.
        (Prices[Amount - 2].onTick == Prices[Amount - 3].onTick))
      Alert("BUG!");
    else if ((Prices[Amount - 1] == Prices[Amount - 2]) &&  // Если цены подряд идущих записей совпадают
             (Prices[Amount - 1].Interval > inMinInterval)) // И временной интервал между ними большой - информируем.
    {
      Alert((Prices[Amount - 1].onTick ? "OnTick-lag! - " : "OnBook-lag! - ") + (string)Prices[Amount - 1].Interval + " mcs.");
      
      ArrayPrint(Prices, _Digits, NULL, Amount - 4, 4); // Выводим подробно проблему.
    }
  }
}

int OnInit()
{
  return(!MarketBookAdd(_Symbol)); // Подписались на стакан.
}

void OnBookEvent( const string &Symb )
{
  if ((Symb == _Symbol) && SaveNewTick_Book()) // Если записали новые цены из стакана,
    Check();                                   // проверяем.
}

void OnTick()
{
  if (SaveNewTick_Tick()) // Если записали цены тика,
    Check();              // проверяем.
}

void OnDeinit( const int )
{
  MarketBookRelease(_Symbol); // Отписались от стакана.
  
  ArrayPrint(Prices, _Digits, NULL, 0, Amount); // Вывод всех записей.
}

结果（机器上只有一个MT5-b2656在运行，CPU负载约为零，一个图表，没有使用测试仪）。

快速卸载机器的中级总数。

CopyTicks滞后于SymbolInfoTick达几秒钟。如果SymbolInfoTick和CopyTicks是在OnTick开始时被调用的，那么在这一点上就没有滞后 - 它们是同步的。
条形图滞后于OnTick，最多几秒钟。因此，不可能通过条形图来检查新的刻度。实时条形图和指标是一个大问题。
在MT5中，OnTick和OnBookEvent可能比它们来到终端时晚几十毫秒到达。因此，应从两个渠道申请当前的蜱虫。

fxsaber 2020.10.26 07:57 #586

向开发商提问。

假设SymbolInfoTick被执行了5ms。打勾是对应于当前时间，还是之前的5毫秒？

fxsaber 2020.10.26 08:16 #587

SymbolInfoTick 的刹车被关闭。其结果是这样的。

如果CPU过载（比如优化甚至不在所有核心上），SymbolInfoTick可能需要几十毫秒才能完成。没有答案，为什么终端中这个最受欢迎的功能没有定期快照。如果可能的话，请把它拍成快照。不要忘记，即使在CPU零负载的情况下，OnTick函数也可能比终端的tick晚工作几十毫秒。

总而言之，相当可悲，但这并不能让那些原始交易的人担心。

对于那些交易 "不原始 "的人来说：硬件必须能够完成任务。

"你是在说 "6/8 "吗？也就是说，6个进程，每个进程在测试期间100%加载一个CPU核心？而且只有4个物理核心？并真诚地感到惊讶的是，在这样的背景下，测试 "变慢了"？

如果这确实是你的理解水平，那么。"学习、学习、再学习"。

如果你想用16-20个线程强奸CPU--至少要买有20个物理核心的CPU。

我相信我可以证明，获得你目前的价格是非常缓慢的。由于MQL5中最重要的功能的不正确实现，CPU负载才会造成这样的迟缓。

fxsaber:

我相信我可以证明，你获取当前价格的实施是非常缓慢的。由于MQL5中主函数的不正确实现，CPU负载只产生了这样的速度减慢。

测试代码。

void OnTick()
  {
   MqlTick Tick;

   ulong gstart=GetMicrosecondCount();

   int   count=10000;
   for(int i=0; i<count; i++)
     {
      SymbolInfoTick(_Symbol, Tick);
     }

   ulong gend=GetMicrosecondCount()-gstart;
   Print(count," iterations, total time ", DoubleToString(gend/1000.0,3)," ms; avr time: ",DoubleToString(gend/1000.0/count,3)," ms");
  }

证明一下吧。
