Vladimir Pastushak:

bool file_exists=(bool)FileGetInteger(FileName,FILE_EXISTS);

In any case it returns true if there is file or not, and error 5019 if there is no file. According to help, it should return false if there is no file.

bool file_exists=FileIsExist(FileName); Works correctly

Please decide which variant of the function you want to use - https://www.mql5.com/ru/docs/files/filegetinteger

I would be comfortable if a macro is mentioned at least once somewhere in #define, #ifdef, #undef, etc. Even if it is not defined.

This is because you have many identifiers in capital letters, whereas there is an unspoken rule that capital letters are reserved for macros (macro highlighting not in colour but in font)

No. Convenient because the logic is unambiguous.

My logic is simple: X before #define X is not yet a macro, and after #undef X it is no longer a macro (respectively X is colored only where it is a macro)

I use mqh, which has no #define, but does have #ifdef. Why they should not be highlighted is not clear.

I've never tried to determine by colour. Moreover, if everything is in #ifdef, MQL4 and MQL5 may have different subcolours. The easiest way is to do ALT+G on macro name to see if it's there or not.

#define  PRICEST_TICK_PRICE //(1)
//...
#undef   PRICEST_TICK_PRICE //(2)
//...
void OnStart()
{
        int PRICEST_TICK_PRICE; //(3)
}

When in line (3) I press ALT+G -> move to line (1).

Question: is the macro there or not?

I don't understand your moaning, to put it mildly. I know how to work with macros. I am well aware of what ALT+G means and how a macro can be undone via #undef. I like this particular editor's behaviour.

Nerdiness is sometimes good, but not in this case.

If earlier there is no #define X, then X in #ifdef X - is not highlighted (*) because - here everything is normal (at least in MetaEditor)

I have only one question to the Developers: why in MetaEditor X is highlighted in #define X, if earlier there was no #define X, while it happens above in (*)

Your question was the opposite: why is X not highlighted on the site

Probably Market or Instant execution
