Try this

this option does nothing at all - I release the script on the chart and nothing happens.

Did the declaration of the variable

string tplName = "FIBOmAGIC СРЕДНЕСРОК.tpl";//ИМЯ ПОДГРУЖАЕМОГО ШАБЛОНА

was by any chance deleted?

If I did, the compiler would yell unidentified variable. But now I'll try again...

I double-checked. The variable isn't deleted. I compile and the script does nothing.

doesn't that work for you?

doesn't that work for you?

If I'm not mistaken, this is where it all started - it didn't work as I recall ;-) And I don't know where to put the template name in the code either. In short, it's kind of a mess...

If i'm not mistaken, that's how it started and it didn't work as i remember ;-)

I already showed it to you - I don't know why it doesn't work for you - it works for me on both mt4 and mt5.

you can also change the colour of the charts

here's another way to change the colour of the charts.

It's just an unavoidable force majeure, it's just a stroke - I might not see something, that's all. But thank you very much for your help.

You don't need to add a .tpl to the code, it's already done for you.

You just need to put in the name of the template.

 Template + ".tpl"

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

sinput string Template           = "ADX";          // Имя шаблона(without '.tpl')

      errTemplate = ChartApplyTemplate(prevChart, Template + ".tpl");
      if(!errTemplate)
        {
         Print("Error ", ChartSymbol(prevChart), "-> ", GetLastError());
        }

you don't need to add (.tpl) to the code, it's already prescribed for you.

you just need to enter the name of the template into the .

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

I think I've got it figured out - next time, please give me the instruction for use, because you won't understand it without a half a litre)))))) ;-) Thanks so much for the help :-)
