Nanex ~ 12-Sep-2013 ~ Gold Futures Halted
On September 12 at 2:54:05, approximately 2000 gold futures contracts traded in a second, sending the
price down just over $10 and causing a circuit breaker to trip, which shut down trading
for 20 seconds. That is the longest halt we have recorded in a widely
traded futures contract. A closer look at the data reveals this was most likely from
one large order to sell at the market.
The next day, Gold again dropped $10 in a second,
but on 2200 contracts and there was no halt.
