Who should solve the problems of last price sticking? The broker or MQ?


 

Does not compile:

template<typename T> 
class A  {  };

class B
  {
   template<typename T> void X(A<T>&);
  };
template<typename T> void B::X(A<T>&)  {  }

It compiles:


template<typename T> 
class A  {  };

class B
  {
   template<typename T> void X(A<T>&){}
  };


What's the catch?


void OnStart(void)
  {
   B b;
   b.X(new A<int>);
  }



'X' - member function already defined with different parameters 
'X' - ambiguous call to overloaded function     
could be one of 2 function(s)   
   void B::X(B::A<T>&)  
   void B::X(B::A<T>&)

This is a known compiler bug, a fix has been postponed for now.

 

Good afternoon!

The copying of signals is not working.

I can see that the signals on the signatory were there, the copying did not take place in the system.

Are you copying to the terminal for Windows desktop version or to the terminal located on VPS?

 
How does local optimization behave when multiple copies of MT5 (potentially different versions) are running andoptimization is running in each of them (maybe not simultaneously)? Judging by the user's message, when you try to optimize one Expert Advisor in one copy, optimization of another Expert Advisor is launched from another copy.

To Windows on VPS.

Already figured it out, as it usually happens, not very smooth hands are to blame))

Thanks for such a quick response!

 

Can't get the funds out of the product sold. The clock has started counting down to the negative side. What's wrong?

 

Can anyone tell me what flags are received when copying ticks

Script code

/********************Script program start function*******************/
void OnStart()
 {
  MqlTick mqlTick[];
  ulong stMSC = D'2020.11.18 20:01:00'*1000, enMSC = D'2020.11.18 20:02:00'*1000;

Exactly the same result from this script

/********************Script program start function*******************/
void OnStart()
 {
  MqlTick mqlTick[];
  ulong stMSC = D'2020.11.18 20:01:00'*1000/*, enMSC = D'2020.11.18 20:02:00'*1000*/;
  CopyTicks(_Symbol, mqlTick, COPY_TICKS_TRADE, stMSC, 93);
  ArrayPrint(mqlTick);
 }/******************************************************************/

If I replace it with COPY_TICKS_ALL, I get flags 2, 4 and their sum of 6. But 312 and 344 are also present. It should not exceed 126. During the trading day we observe 56 and 88 when requesting COPY_TICKS_TRADE... Why so many?
