Investing.com is a site I frequently reference both in my online webinars and also on my various social media channels, as it is one of the most comprehensive you will find for all markets. The business model for the site is based on advertising, so all the content is free, and there is a wealth of data for all the markets as well as live data, particularly for futures. This is truly a gold mine site where you will find a wealth of unusual tools, data, analysis, and commentary. It’s a great place to find live data on US fixed income.
