Unfortunately, there is no such function. Or rather, there is, but in the protected area.

Is there a way to find out which indicators the user has selected to receive signals?

In what case can an array not be set as a timeseries? Trying this and it doesn't work:

   ResetLastError();
   //---
   double Array[4];
   //---
   err=GetLastError();
   //---
   if(CopyBuffer(Handle,0,0,4,Array)<0)
     {
      Print("Неудалось скопировать значения в массив! Ошибка ("+IntegerToString(err)+")");
     }
   else
     {
      if(!ArrayIsSeries(Array)) 
        { 
         Print("Установим, как таймсерию!");
         //---
         if(!ArraySetAsSeries(Array,true))
           {
            Print("Неудалось установить, как таймсерию! Ошибка ("+IntegerToString(err)+")"); return;
           }
        }
      //---
      Print("Есть контакт!");
      //---
      Print("Array[0]: ",Array[0]);
      Print("Array[1]: ",Array[1]);
      Print("Array[2]: ",Array[2]);
      Print("Array[3]: ",Array[3]);
     }

The documentation says https://www.mql5.com/ru/docs/array/arraysetasseries

Specifically, in your case, you are trying to change the way you access a static (predefined dimension) array

Why? You, as a developer, already know which indicators you use

Thank you. Got it. I read the help, but didn't understand it. But your words immediately clarified it.)))

the plugin library doesn't know what indicators are used. Because in the MQL Wizard indicators can be set arbitrarily when creating an EA.

Why does the plug-in library need to know the indicators?

To add strategies based on the selected indicators.

CopyHigh - maximum barprices. It turns out the maximum Bid prices. How do I get the maximum Ask prices for the bars?

Probably, we can get the maximal price of the bar and add to it the spread on that bar.
