square brackets alone
Thank you... Although it would be better (for us dummies), of course, if such things were indicated in words in the Documentation. Because who knows: it's a strict description (like in mathematics), which retains its meaning in all formulas and all places where it (the description) applies OR it is a schematic description, which aims to show that a given parameter is just an array, and not a variable or constant, or God knows what else
 
Dear Experts, Please help.
I can't overcome the problem of automatic saving of template.
It does not insert file name in save window.
Here is the code.
// Функция выгрузки файл шаблона с текущего графика
     string slash=StringSubstr("\a",0,1);
     string path="experts\files";
     if(IsTesting()) path="tester\files";
     SaveTemplate(StringConcatenate(TerminalPath(),slash,path,slash,Symbol(),"-",TimeCurrent(),".tpl")); //загрузка шаблона с именем 
 
void SaveTemplate(string lpTemplateName)
{
    int hParent, hDlg, hEdit,hButtonSave ;
    hParent = GetAncestor(WindowHandle(Symbol(),Period()),2);
    PostMessageA(hParent,WM_COMMAND,33220,0); //вызываем окно сохранения шаблона
    Sleep(100);
    hDlg = GetLastActivePopup(hParent);//основное окно
    hEdit = GetDlgItem(hDlg,0x3E9);//поле имени файла
    SetWindowTextA(hEdit,lpTemplateName); //вводим имя шаблона
    // 0x45A
    hButtonSave = GetDlgItem(hDlg,1);             //определяем дескриптор кнопки "Сохранить"
    Print(lpTemplateName," ",hEdit," ",hDlg," ",hParent," ", hButtonSave);
    PostMessageA(hDlg,WM_COMMAND,1,hButtonSave);  //нажимаем на кнопку

}

 Thanks in advance.

Tested it recently. It works.

I don't agree. No need to go beyond mql, no need to remove the EA from the chart. It's enough to programmatically block the trade by providing for this in the EA's code.

Let me disagree with you (watch to the end) :

Yes, that's right! The only exception is for remote management.
 

Do you know, please advise, there is a code section in the advisor, it is necessary to know how the previous candle closed on two pairs at the opening of a new candle, everything works fine, but if at that moment there are ticks on two pairs, the advisor is on the main pair and there are no problems with it, but if the second pair with the beginning of a new candle has no ticks, the values from it are not updated and receive data from it, not from the previous candle, but from the day before.

{//1
if (iClose(SignalSimbol,PERIOD_H1,1) > iOpen(SignalSimbol,PERIOD_H1,1)) svcolor1 = 1; // бычья свеча
if (iClose(SignalSimbol,PERIOD_H1,1) < iOpen(SignalSimbol,PERIOD_H1,1)) svcolor1 = 2; // медвежья свеча
if (iClose(SignalSimbol,PERIOD_H1,1) == iOpen(SignalSimbol,PERIOD_H1,1)) svcolor1 = 3; // додж
