Wrote to the SD, has anyone noticed this in themselves? I directly copied the message

Terminal version and bit rate

...1653

Description of the problem

...The cursor in the chart field sometimes becomes text instead of a pointer, i.e. a vertical stick, like in an editor.

Sequence of actions

...Occurs completely randomly. It helps to return to the standard trading chart bar. Sometimes this hovering becomes an arrow rather than a handle. And sometimes it will wiggle on the chart and returns to normal itself.

The result is as follows

Expected result

The indicator does not unload

#property indicator_buffers 0
#property indicator_plots indicator_buffers

int OnInit()
{
  return(INIT_FAILED);
}

void OnDeinit( const int )
{
  Print(__FUNCTION__);  
}

int OnCalculate( const int rates_total, const int, const int, const double &[] )

Loading and unloading indicators

Indicators are loaded in the following cases:

• attaching an indicator to a chart;
• start of the terminal (if an indicator was attached to a chart before the terminal was previously closed)
• loading of a template (if an indicator is attached to a chart)
• Profile change (if the indicator is attached to one of the profile charts);
• change of the symbol and/or period of the chart, to which the indicator is attached;
• after the successful recompilation of an indicator, if this indicator has been attached to a chart.
• change of indicator input parameters.

Indicators are unloaded in the following cases

• when the indicator is detached from the chart;
• closing of the terminal (if an indicator has been attached to a chart)
• loading of the template if an indicator is attached to the chart;
• close the chart to which the indicator has been attached
• profile change, if the indicator is attached to one of the charts of the profile to be changed;
• change of the symbol and/or period of the chart, to which the indicator is attached;
• change of indicator input parameters.

There is no mention of the other cases. Or add the word "only":"Indicators are unloaded only in thefollowing cases".

I will add this to complete the picture.

FileFindFirst

Starts scanning the files and subdirectories in the appropriate directory according to the specified filter.

long  FileFindFirst(
   const string   file_filter,          // строка - фильтр поиска
   string&        returned_filename,    // имя найденного файла или поддиректории
   int            common_flag=0         // определяет область поиска
   );

If I set filter "*.bin", it gets all files with bin extension only. How to set filter to get only files without extension?

It seems that you can't. The filter has very limited options in this function.

But it is possible to filter additionally afterwards, because you have access to the name.

Thanks, I thought it could be done in one step.

It works in MT4.
