How to get a content of a page that updates too often using webbrowser in C#

问题

I would like to get the latest content of a page that updates too often, for example, https://www.oanda.com/currency/live-exchange-rates/ (prices update every five second on weekdays)

I am using the following code:

        var webBrowser = new WebBrowser();
        webBrowser.ScriptErrorsSuppressed = true;
        webBrowser.AllowNavigation = true;
        webBrowser.Navigate("https://www.oanda.com/currency/live-exchange-rates/");

        while (webBrowser.ReadyState != WebBrowserReadyState.Complete) {
            Application.DoEvents();
        }
        string myData = webBrowser.DocumentText;

But that does not return me the latest info as shown in the page. Eventually I would like to re-parse that page and get the latest data a few minutes/seconds later.

Any ideas?
