Absolutely, they allow you to go short or long for all industrial and precious markets available.
What this means is the investor can speculate on prices falling and rising, so an investor can profit both ways.
For more information, let them know how much you wish to begin with (minimum is $6000 as explained in an earlier post), your skype ID and/or your phone number. They are on London time.
