Customizing the Ticker
Your Ticker can either display the most active stocks and top news or just stocks and news related to your portfolio. To change what your Ticker displays, first click on Settings at the top of the Playground.
In the middle of the center column, under Ticker Options, toggle the appropriate button next to what you want your ticker to display.
To make your changes permanent, click on Save on the upper right hand corner of the Settings menu.
