What I don't understand on the SB platform is that you get the same message, but there are prices quoted for various futures contracts. I suspect but I maybe wrong that these are reserved for professional clients
I agree that its very frustrating trying to get through to ask the question and I have not seen anything in their training documentation / courses with the meaning of this
Surely the big advantage of SB is the lack of capital gains tax, and yet you are limited with what you can trade on
Very poor in my opinion
