I have a potential client who sells precious metals. They want a website with live stock exchange prices similar to the one on www.hattongardenmetals.com
Is there a widget for this? Or is it possible with Muse?
Such stuff requires a dynamic server backend and since no doubt it falls under a million regulatory rules it will have to come from certified providers such as the one you linked already. so no, this is nothing you would do in Muse nor probably should even try to stay out of trouble with authorities.
