Nanex ~ 25-Mar-2013 ~ eMini Algo Disaster on 14-Jan-2008
On January 14, 2008, in the early hours of trading, prices of the March 2008 eMini (ES)
futures contract began oscillating rapidly. After about 4 seconds and 100 oscillations,
the price swings widened to the equivalent of about 400 points on the Dow Jones Industrial
Average. The oscillations then abruptly stopped and in less than 2 seconds, the price collapsed 5.3% from its peak: the equivalent of a 760 point drop in the Dow. After reaching
bottom, the market was halted for 10 seconds. Prices returned to normal levels within
the next few minutes. Between 5:30am and 8:00am that morning, the exchange canceled
most of the trades.
