Install Metatrader 4
At this point, your broker should have given you the Metatrader 4 installation package.
Close the demo account dialog
By default, Metatrader shows the demo account creation dialog. Press cancel at this point as you already have real account credentials that were given to you by the broker when you created your account.
Enter your login credentials
In this dialog, enter your login credentials that were given to you by your broker. If you can login correctly, you already have Metatrader 4 correctly installed on your machine.
At this point, you can proceed to install RobinVOL.
