A rogue trader is basically a trader (typically a derivatives trader – a person dealing with futures, options, etc) who makes unauthorised trades. They may have started to do this to cover up a loss made in an authorised trade. The best known case is the Nick Leeson/Barings Bank one, where he lost an absolute shitload of money and sunk the bank.
So, umm, what is a rogue trader? I never heard anything about these guys.
