The Earnings Calendar gives the ability to filter the tickers by either Exchange or Market Cap. There are two buttons available at the top of the calendar, Exchange and Market Cap. If there is an asterik on this box, then a filter is being applied.

As you can see in the screenshot below you can select the exchanges you want to see in the calendar. If none of them are selected then the calendar is looking at all the exchanges.

The Market Cap filter is available as seen below where you can enter the value in millions and filter based on this amount.
