How timely is your price data?
So-called ‘Real time' market price data offered via a website is not always instant – it can be delayed by minutes. Even when it is not delayed, you must refresh the page in your browser to see the latest prices. If you really want to be sure you are seeing up-to-the-second prices, get ‘dynamic' data which updates on the page before your eyes without you having to refresh the page. This is usually a more expensive option.
