Is there a way to use simultaneously both the Invest and CFD in different tabs? Everytime I login to one, system logs me out from the other
Welcome to the Community, @mainasdion 
Using your account from two different devices or two separate tabs is not possible for the moment. This feature is not present mainly due to account security measures.
Still, I understand how this can be useful and will forward your feedback. We’ll share the news should this be introduced in the future
