Rashid Umarov:

For example

Slightly reworked

string GetTickFlag( uint tickflag )
{
  string flag = "";

#define  TICKFLAG_MACRO(A) flag += ((bool)(tickflag & TICK_FLAG_##A)) ? " TICK_FLAG_" + #A : "";
  TICKFLAG_MACRO(BID)
  TICKFLAG_MACRO(ASK)
  TICKFLAG_MACRO(LAST)
  TICKFLAG_MACRO(VOLUME)
  TICKFLAG_MACRO(BUY)
  TICKFLAG_MACRO(SELL)
#undef  TICKFLAG_MACRO

  if (flag == "")
    flag = "FLAG_UNKNOWN";
     
  return(flag);
}

Result

2016.09.14 13:52:33.925 Test (Si-9.16,M1)       Tick23: time = 2016.09.13 18:52:35.505 bid = 0.0 ask = 0.0 last = 65253.0 volume = 35  TICK_FLAG_BID TICK_FLAG_ASK

It turns out that both prices change to zero from non-zero values. And after zeros go back to non-zeros.

Indicator shows that CopyTicks may not be giving away the last ticks

Even more interesting

string GetTickFlag( uint tickflag )
{
  string flag = "";

#define  TICKFLAG_MACRO(A) flag += ((bool)(tickflag & TICK_FLAG_##A)) ? " TICK_FLAG_" + #A : "";
  TICKFLAG_MACRO(BID)
  TICKFLAG_MACRO(ASK)
  TICKFLAG_MACRO(LAST)
  TICKFLAG_MACRO(VOLUME)
  TICKFLAG_MACRO(BUY)
  TICKFLAG_MACRO(SELL)
#undef  TICKFLAG_MACRO

  if (flag == "")
    flag = " FLAG_UNKNOWN (" + (string)tickflag + ")";
     
  return(flag);
}

#define  TOSTRING(A) " " + #A + " = " + (string)Tick.A

string TickToString( const MqlTick &Tick )
{
  static int i = 0;
  
  i++;
  
  return("Tick" + (string)i + ":" + TOSTRING(time) + "." + (string)(Tick.time_msc %1000) +
         TOSTRING(bid) + TOSTRING(ask) + TOSTRING(last)+ TOSTRING(volume) + GetTickFlag(Tick.flags));
}

bool MySymbolInfoTick( const string Symb, MqlTick &Tick, const uint Type = COPY_TICKS_ALL )
{
  MqlTick Ticks[];
  const int Amount = ::CopyTicks(Symb, Ticks, Type, 0, 1);
  const bool Res = (Amount > 0);
  
  if (Res)
    Tick = Ticks[Amount - 1];
  
  return(Res);
}

CopyTicks can both lag behind and be ahead of the Event-tick. Event-tick often has a zero flag.

ZZY Correct the MqlTick flag to flags in the MqlTick help.

How others use CopyTicks is beyond me. No trust, unfortunately. Very raw.

The tick that was in the history is already absent in the next Tick-event!

Dear developers, bring CopyTicks to a working condition. Even simple tests are failing.

At the moment CopyTicks with some stretch, but works in real time with input parameter from == 0.

I need to add new history ticks to the array on each OnTick. Has anyone implemented this?

I'm struggling - it's not working. I can't manage to bypass curvature of CopyTicks.

Here is one of the stretches
void OnTick( void )
{
  MqlTick Ticks[];
  
  const int Amount = CopyTicks(_Symbol, Ticks);
  
  if ((Amount > 1) && (Ticks[Amount - 1].time_msc < Ticks[Amount - 2].time_msc))
    Print("Некорректная история!");

We take the edge ticks, and find that the most recent tick has less time than the previous one.

This applies only to COPY_TICKS_ALL. With the other modes, the suggested EA has not detected any errors.
Do I have to write to Service Desk about the reports in this thread or do the developers monitor it themselves?

You'd better write to them. It won't be superfluous.
