Here is a very interesting question:

---

There is a need to prohibit the EA from working on metals.

Of course, we can go "straightforwardly" list all possible metal symbols. Or at least set the search for a substring in the string of symbols... But I am interested if there is a nice way out, original short code for determining which group the symbol belongs to. Or something else interesting.

Please advise if someone already encountered with this question and know the solution.

Here is an example:

   string path=SymbolInfoString(Symbol(),SYMBOL_PATH);
   if(StringFind(path,"Metals",0)>-1)
     Print("Символ "+Symbol()+" относится к группе металлов.");

NEED HELP!!!!
Why is there no signals tab in MT4 in the terminal and settings?

Because your dealer has disabled this tab! It's best to ask your dealer about it.

Another option is to open your account in the terminal from another dealer.

Beautiful, thank you.

And why didn't I see it when I was digging through the documentation? )))

Some tips for MQL5 beginners!!!

I don't understand why the compiler gives error 'starttime' - declaration without type:

datetime starttime=D'00:00:01';

datetime endtime=D'23:59:59';

MqlDateTime startday,swapday,endday;

void TimeToStruct(starttime,endday);

void TimeToStruct(endtime,endday);

startday.day_of_week=1;

swapday.day_of_week=3;

endday.day_of_week=5;

Dear transcendreamer gave me a detailed answer! Maybe someone will need it:

calculation is correct only for cadchf it should be 0.0001*100000/USDCAD/CADCHF
but in general there is a simple way - I will describe how I do it:
it's simplistic, but it works everywhere
look at the essence of the instrument, any instrument has a basis and a gauge
basis = what we trade = for cadchf it is the Canadian dollar= so we trade cad
gauge = what we quote basis = in this case the franc
so initially the financial result of any transaction will be in francs
so you have to convert the francs into the currency of the deposit(usd)
so we take usdchf - this is how many francs this is how many francs for 1 dollar
and we need the opposite - how many dollars for 1 franc
i.e. flip 1/x where x=usdchf
then as a result for the 4-digit point value we get 10 / usdchf = 10. 37
this can be done with any instrument knowing its quoted currency
