I have one subscription running on my MT4.
Tried to add one more but failed.
Is it possible to have more than one subscription on an account?
I just remembered.
When I started with MT4 a couple of years back I found out that it worked to run more than one instance of MT4 to the same account.
Unless some changes has been done to MT4 that prohibit this, that would be the solution.
That will not work with Signals service.
Please read the rules :
IV. 7. One trading account can be subscribed to one Signal only.
So I have to have several accounts and use my PowerTradeCopier
