About copying the trades between accounts.

 
Hello everyone, I have a question!

I have two accounts: one is MT4 and other one is MT5. I want to copy my trades between each other.
If I make my MT5 account as a signal provider, can I copy my trades to MT4 account?
Or does signal copying work only from MT4 to MT4 or vice versa?
What do you suggest?

Thanks!

Yes, from MT4 to MT4 (or from MT5 to MT5).
