I badly need something like this right now. As I understand it, brokers rule this segment. This would essentially be an online broker. My current broker sends me pdf brochures on request which I think is a pretty bad experience, so this would be a welcomed change for me. On the other hand, sometimes I also like to have a single point of contact. If my broker had access to using this platform, that would be an ideal scenario. It could allow me to research and compare at my leisure, but have a strong contact point when I need it.
