When you're trying to share a chart to social media or an email newsletter, there's a quick way to do it.  From the top right corner of the chart, there are two icons.  The one with the down arrow is the Download icon, and the one with two rectangles is the Copy icon.

When you Download a chart, it will appear in your downloads folder.  Some browsers will even show the downloaded file in a pop-up box to easily access it.

If you choose to Copy the chart, you can then paste it into your platform or media of choice (CTRL+V on windows, Command+V on Mac). 

Whether you download or copy a chart, note that it won't contain a title or description of the chart.  Be sure to take a note on what you copied so you can include it in any content you're writing about the market.
