Metal Bulletin’s Andrea Hotter looks back over the history of metal trading in London, talks to the London Metal Exchange’s ceo Martin Abbott about the future of the exchange – set up in 1877 and bought last year by Hong Kong Exchanges & Clearing for £1.39 billion ($2.1billion) – and asks a broker to demonstrate and explain some of the hand signals by which business is still carried out on the last open outcry trading floor in Europe.
