Those are StyleButtons. StyleButtons allow our Extra members to quickly switch between different ChartStyles that they have previously saved.

For example, let's say that you have three different ways of analyzing a stock - one with a 30-minute view, one with a daily view and one with a weekly view. You can now create three different ChartStyles (let's call them "ShortTerm", "Daily" and "Weekly") and assign each one to a StyleButton. Then, the next time your friend sends you the ticker symbol of their next "sure thing", you can simply create a chart for that stock and then click on your three StyleButtons to see if you agree.
