CopyTicksRange () does not work correctly in MQL5. a

New comment
 

I'm trying to get the marks for different times. I've been using the CopyTicksRange () function. It used to work fine.

But it suddenly stopped working. I am very disappointed with this behavior of the function.

Please explain me why this is happening? What is the best way to get ticks using Time range with guarantee?

I tried to call this function several times because I thought it takes time to load Ticks data. But all the times I tried, the length of the copied ticks was -1.

Please let me know what I can do.

I have set Tools -> Option -> Charts -> Maximum number of columns in chart to Unlimited. I tried the following code:

 int len = CopyTicksRange(Orig_Symbol_Name, ticks_add, COPY_TICKS_ALL, ulong(CURRENT_TIME)*1000, ulong(TimeCurrent() + 60) * 1000);

   if(len<=0)
     {
      string error;
      if(GetLastError() == 4401)
         error = "ERR_HISTORY_NOT_FOUND";
      else
         error = string(GetLastError());
      Print("------------------------------------------------------------------");
      Print("History Tick Length: ", len, " Error: ", error);
      Print("------------------------------------------------------------------");
      return -1;
     }
 

Do you call this code where? In what type of programme?

Where are the variable initialisations?

Where is the full MQ5 code as a file - so it can be compiled and run?

 

An example script is provided in the CopyTicks help

I'm trying to get the marks for different times. I've been using the CopyTicksRange () function. It used to work fine.

But it suddenly stopped working. I am very disappointed with this behavior of the function.

Please explain me why this is happening? What is the best way to get ticks using Time range with guarantee?

I tried to call this function several times because I thought it takes time to load Ticks data. But all the times I tried, the length of the copied ticks was -1.

Please let me know what I can do.

I have set Tools -> Option -> Charts -> Maximum number of columns in chart to Unlimited. I tried the following code:

ulong(TimeCurrent() + 60) * 1000 is time in the future. There are no ticks there yet. You do not know what time you are trying to get the ticks from. Try to put it like this 

int len = CopyTicksRange(Orig_Symbol_Name, ticks_add, COPY_TICKS_ALL, ulong(TimeCurrent() - 60)*1000, ulong(TimeCurrent()) * 1000);

It will be the ticks for the last 60 seconds

I won't be able to share the full code, but here's a small example I used.

 
Could you suggest me now? I have tried the example above. Sometimes it works. But not always.

Try this option

//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int OnCalculate(const int rates_total,
                const int prev_calculated,
                const int begin,
                const double &price[])
  {
   if(rates_total == 0)
     {
      if(Fill_Ticks_Symbol(Symbol()) <= 0)
        return 0;
     }

//--- return value of prev_calculated for next call
   return(rates_total);
  }
This way the indicator will wait for the ticks to load.
 
Alexey Viktorov :

Try this option.

This way the indicator will wait for the ticks to load.

I don't think there will be any difference. Because the problem is with the MQL5 function, not the one I created.

This is not the first time you've expressed an unverified opinion. What prevents you from checking?

Try to count how many mql5 programmers are working with CopyTicksRange() function and no one has problems. You are the only one, you are the only one who has such behavior of the function.

A very bold statement, Alexey.


I work with CopyTicksRange() function and it constantly works incorrectly. To make it work properly, I have to adjust input parameters so that it gives a sensible result. I have been using this function for two years and keep finding new glitches. Support keeps ignoring all the questions about this function. Most likely they are too lazy to do it, as there is one glitch after another.

As an example, what this function can do unexpectedly:


1) return the ticks not included into requested range

2) return all the ticks of the current bar instead of the requested part of this bar

3) return the rubbish, i.e. it is not clear what ticks are returned

4) to skip a part of ticks


The best thing was an advice of someone from support to make crutches - i.e. if I know in which situations a function glitches, I should reword the request so that it wouldn't glitch. I've been doing that ever since :)


Here's yesterday's example, against which I'm now looking for a crutch:


MqlTick Ticks[1000000];

int AddTicks(ulong tFrom_msc,ulong tTo_msc,ulong &lt)
{

   int  received=CopyTicksRange("@BR",Ticks,COPY_TICKS_ALL,tFrom_msc,tTo_msc);
   
   PrintFormat("CopyTicksRange:  %s:%d - %s:%d  received %d",TimeToString(tFrom_msc/1000),tFrom_msc%1000,TimeToString(tTo_msc/1000),tTo_msc%1000,received);
   
   if(received>0)
   {
       PrintFormat("%s:%d - first tick, %s:%d - last tick", 
                              TimeToString(Ticks[0].time_msc/1000),           Ticks[0].time_msc%1000, 
                              TimeToString(Ticks[received-1].time_msc/1000),  Ticks[received-1].time_msc%1000
                              );
                              
       lt= Ticks[received-1].time_msc ;                   
   }
   return received;
}

And here's the crutch:

2021.09.18 18:10:26.541 TesterEx ($BR,H1)       CopyTicksRange:  2021.01.29 23:56:864 - 2021.01.31 23:59:999  received 109425
2021.09.18 18:10:26.541 TesterEx ($BR,H1)       2021.01.29 00:02:782 - first tick, 2021.01.29 23:56:863 - last tick

I.e. function, used by thousands of programmers, personally returned to me all ticks from the beginning of the current bar, but not included into requested range

I highlighted the keywords.

Do NOT request ticks that don't already exist by definition. If you request ticks even one millisecond beyond current time in milliseconds, you will get the very g.........y in the form of your problems.
