Audacious Oligarchy: The Double Flash Crash In Gold – Sept 13, 2012

The ‘Dr. Evil’ strategy in two pictures.

From Nanex Research:

Trading was so furious in Gold, that the CME circuit breakers triggered and halted the futures contract for 5 seconds. First on the downside, then on the upside. This is the same circuit breaker that triggered only once in the eMini during market hours: that time was at the bottom of the flash crash on May 6, 2010.

The first halt in the December 2012 Gold Futures contract (GC.Z12) was at 12:14:44: you can see the gap in volume in the lower panel of Chart 1. One second before the halt, 2,000 contracts traded the price down $10, from $1,730 to $1,720. The CME halt logic triggers a 5 second market pause whenever orders appear that would remove all available liquidity and move the price by a certain amount.

For this event, this basically means that if this order represented a true intent to sell, then we should expect additional selling (from the balance of the order that triggered the halt) when trading resumes.

However, in this case, the additional selling did not materialize, which leads us to believe the large sell order was meant to disturb any market based on the price of gold. And disturb the markets, it did.

Note the gap showing the halt after the drop. The depth of book shows orders continue to be added/removed from the book during the halt.
