Today's HFT Example

• Courtesy of Zero Hedge...today's example of HFT run amok.  These have been happening in different stocks the past few months.  The games have not stopped and this is another incident of proof.  
• Click on the above bid-ask grid to make it larger...then look at the price column on the left side.  From $43 down to $4 and back into the $40's all in less than one second.
• Where was the 10% circuit breaker that was put in place after May's Flash Crash???
• How people can feel genuinely at ease in this type of market continues to puzzle me.
