When viewing your list of companies in the Your Watchlists section, each company has a coloured traffic light next to it. This is designed to show you how much news is currently available for each company.
Green companies have the most news. If the light is red, there are no news articles to display for this company.
The amount of news available for a company can be affected by your chosen Watchlist settings, such as date range and topic filters. These can be updated by clicking on the Watchlist name and going to the Settings tab.
