London Metal Exchange

From the longer Wikipedia page

The London Metal Exchange (LME) is the futures exchange with the world's largest market in options and futures contracts on base and other metals. As the LME offers contracts with daily expiry dates of up to three months from trade date, weekly contracts to six months, and monthly contracts up to 123 months,[1] it also allows for cash trading. It offers hedging, worldwide reference pricing, and the option of physical delivery to settle contracts. Since 2012 it has been owned by Hong Kong Exchanges and Clearing after LME's shareholders voted in July 2012 to approve the sale of the exchange for a price of £1.4 billion.
