The London Metal Exchange plans to cancel some aluminum trades made on its Select electronic trading system at 1 a.m. local time, a bourse official said.
The cancelation covers 220 lots of the three-month contract traded in a 21 second period after the open, the official from the bourse’s help desk said by phone. One lot is equal to 25 metric tons of metal. Aluminum fell as much as 3.3 percent to $2,286 a ton at the open, according to data compiled by Bloomberg.
Stephen White, a spokesman for the exchange, didn’t immediately respond to a voicemail left on his mobile phone seeking comment, outside of normal business hours.
