Urain:

I didn't clarify this question at the time, and now I'm having doubts.

What's the right way to reserve memory?

like this

or as follows

And correct the help, it's very ambiguous.

ZS In the given variants it is implied that the size of allocated memory taking into account reservation should be 2016.

At the moment it works like this

ArrayResize(array,10,2000);

This will allocate a buffer for 2010 elements and 10 of them will be available.

This mayprobably change in the near future.

Thismight change soon.

Why not 2000 buffers of which 10 are available?

This makes more sense in my opinion.

I get it, somewhere like this:

int reserved=0;// размер распределённой памяти
//+------------------------------------------------------------------+
//| изменение размера массива                                        |
//+------------------------------------------------------------------+
int Resize(int size)
  {
   int step=4;// резервирование с шагом 2^4=16
   int new_reserv=0;
   if((size>>step<<step)>=reserved)
     {
      reserved=((size>>step)+1)<<step;
      new_reserv=reserved-size;// сколько памяти нужно дорезервировать      
      ArrayResize(arr,size,new_reserv);      
     }
   else ArrayResize(arr,size);     
   Print("ArrayResize(arr,"+size+","+new_reserv+"); reserved="+reserved);
   return(size);
  }

...

This couldprobably change in the near future.

What's wrong with the current redundancy scheme?

I don't know if it's a bug or not, but when optimizing Expert Advisors based on a heavy indicator like CCFp(Cluster Indicator) at the end of the pass the following window pops up on the local agent: Strategy Tester Agent has stopped working.

When closing this window the program does not pop up and in a couple of seconds continues optimization, and the results of the pass are recorded in the report.

The following information is present in the EA code

void OnDeinit(const int reason)
{
IndicatorRelease(CCp_Handle);
}

If the IndicatorRelease(CCp_Handle); line is commented out, optimization goes without errors.

I am not good at programming, but my question is: When do I need to use this function in indicators and Expert Advisors? In my code of CCFp indicator it also uses deinitialization with releasing of handles of a heap of muvings.

Please write to Service Desk. Attach source code and optimisation conditions.

I want to use external variables in the script so that I can set the required value before running it. In MT4 this was implemented using #property show_iputs, but in MT5 it is not possible (there is #property script_show_inputs, but it does not give anything). If anyone has faced such a question, please advise how to do it.

Wouldinput variables work?

Thank you, it all works.

Shit... The terminal comes with so many examples... ...so many examples... SymbolInfoSample.mq5 script, for example
