Hi,
I'm purely a currencies trader and not checked it before. Not sure if anyone was aware, I know I wasn't, that this WHC metatrader I have linked to below provides free, real time, futures and stocks, forex, grains, metals, commodities and everything else you can think.
Once opened you can click on tools > market watch > right click on the quotes > select 'show all' > and hey presto, everything.
I do not know, nor vouch for its accuracy but for newbies and back up charts, it seems a very viable extra. It expires every 90 days but you just open a new account and start again.
Hope that's helpful to some?!
