double tenkan,kiju,chinku;
   tenkan=iIchimoku(Symbol(),PERIOD_H4,12,24,120,1,0);
   kiju=iIchimoku(Symbol(),PERIOD_H4,12,24,120,2,0);
   chinku=iIchimoku(Symbol(),PERIOD_H4,12,24,120,5,0);
   
   Print("tenkan:",tenkan," kiju:",kiju," chinku:",chinku);

chinko span output 0, what is the problem?

Tell me why there might be an error 130

Stops too close or incorrectly calculated or non-normalised prices in the stops(or in the Level price of the pending order opening).

Don't bother - you don't know what it may be - it may be many things - everything that matches the description of this error... why guess? :-)

ERR_INVALID_STOPS 130 Incorrect stops

Make it a rule of thumb to ALWAYS make the necessary checks when placing or opening an order from the market, and modifying it.

Everything.

О! Sorry - it turns out you were the one who answered... :-) And I am answering you... :-)

Don't sweat it - who knows what it could be - lots of it - everything that matches the description of the error...why guess? :-)

ERR_INVALID_STOPS 130 Incorrect stops

If you have a good faith in a market order, you should always make the required checks when you set or open it, as well as when you modify it.

Everything.

It cannot be stored anywhere in the terminal, because leverage can be floating and only the server can know about it. In my opinion, the most correct way of calculation is as follows:

I've read and thought about it, and did it my way, but the question arises - is the separator in numbers of double type always equal to dot?

void start()
  {
   double x = MathMin(MarketInfo(Symbol(), MODE_MINLOT),MarketInfo(Symbol(), MODE_LOTSTEP));

   Comment(digits(x));
  }
//+------------------------------------------------------------------+
int digits(double number)
  { 
  string y = DoubleToStr(number,8);
  int k = StringLen(y)-2;
  
  for(int i = -1; ;k--)
    {
    string x = StringSubstr(y,k,1);
    if(x != "0" && i < 0) i = k;
    if(x == ".") return(i-k); //Разделитель в mql4 всегда равен - точке?
    }
  }

Yes. It's a programming language, it's not Excel or handwritten text.

How to terminate an Expert Advisor programmatically - something like terminate(0) ?

Does MQL4 have such a possibility, or is it only possible to terminate an Expert Advisor manually?

Thanks in advance.
