Error in MQL5 Reference / Trading Functions / OrderGetTicket

In the example given in the article the line

type          =EnumToString(ORDER_TYPE);

will not return the order type.

Why can't I download a demo version of a paid indicator for MetaTrader4 from Market?

What's the difference? And then it's a runtime error, not a compilation error.

I mean, macros are designed for strings and NULL is not a string literal and there's no problem replacing it with ""

[A100]

It's probably not about the macro

void OnStart()
{
        string str1 = "" + NULL;        //нормально
        string str2 = NULL + "";        //нормально
        string str3 = NULL + "" + NULL; //ошибка выполнения
}

[A100]

The string is converted to int and there is no warning

void f( int x )          { Print( "f1=", dt ); }
void f( const string& x ) { Print( "f2=", dt ); }

void OnStart()
{
        f( "AAA" );
}

Result: f1=100

A100:

How about this?

void f( string x )

[A100]

TheXpert:

How about this?

void f( const string x ) { Print( "f2=", dt ); }

So the result: f2=100, so I think the warning should be higher

Hi all. I followed the link that questions about bugs and glitches in MQL4 should be posted here. or is it wrong?

It's better to post it here

It shouldn't be a warning, it should be selecting the correct function. And the line to the int is not a warning, it should be an error, imho.
