answer:Most financial news websites – I know that CNBC is one – have their own apps that do this specifically. I know that Yahoo! used to offer that service, too – and maybe they still do also, but I haven’t checked it out in a long time. The problem with using those sites is that if you do any kind of more-than-minimal trading, you have to keep updating the third-party site repetitively (and keep account of splits, too, of course, and dividend reinvestment if you do that), so I simply don’t do that any more. I go direct to the trading site where I have my account, but I require a manual login each time. I don’t save passwords on my phone!
