Boris Egorov:
What does it mean: No IPC connection?

no terminal connection

you must have called MT5Shutdown() and are trying to get quotes.

[Boris Egorov]

Maxim Dmitrievsky:

no connection to the terminal

Probably you have called MT5Shutdown() and are trying to get quotes

No, I just called the symbol wrong.

Problem when running, error 4014 when creating socket in mql5, says I can't use socket with expert. Any ideas?

I'm also getting error 4014 when creating the socket in mql5

[Joao Vitor Farias De Castro]

Has anyone managed to resolve the 4014 error situation?

Hi all

Note

Connection address should be added to the list of allowed ones on the client terminal side (Tools \ Options \ Expert Advisors).

If connection fails, error 5272 (ERR_NETSOCKET_CANNOT_CONNECT) is written to_LastError.

The function can be called only from Expert Advisors and scripts, as they run in their own execution threads. If calling from an indicator,GetLastError() returns the error 4014 - "Function is not allowed for call".
