Customize the toolbar on your chart to your specific needs. Display data that you always want to see at a glance and add buttons for commonly used features.  

This feature allows you to compare a stock's performance to an index or even another stock. You can enter up to 10 symbols to plot on the chart alongside the main symbol, as well as the sector and industry averages for the symbol. They can be turned on and off individually and you can set different colors for each.
