Stock or CFDs?
Ask the broker.
I think - if your account is connected with some stock exchange so it may be the real stock.

For now, I suggest better invest in stocks and if ever you'll be good enough you can also start investng in CFD. As of this moment, you really have to be updated in reading International Stock Market news.

How can I know if on metatrader 5 I'm buying a real stock or just a CFD? Is buying real stock even possible through this platform?
Thanks.
