To signup for the premium access, you can either go to http:/www.medvedtrader.com/login then login and click on either CHANGE PLAN or the pricing menu and select one of the paid options, OR, in MT you will notice that there is a big signup TILE on the dashboard. If you click on that, it will take you to the correct pricing page on the website, already logged in.
