Nanex ~ 20-Dec-2012 ~ BATS Redux in FBSS
On December 20, 2012, starting at 12:07:38, the stock of
Fauquier Bankshares, symbol (FBSS) got hit with the BATs experience.
The price dropped from $12.17 to $6.46 in about 2/10ths of a second, triggering a halt. Every trade had the condition "ISO" meaning
this was the work of a High Frequency Trading algorithm - some of which are unsafe at
any speed. This event is another clear sign that nothing. Nothing! Has changed.
