19-AUG-2013 50+ Trade Halts... No Trades

Today, August 19, 2013, we received over 50 trade halts. Most of these occurred with almost NO trades having happened. When an entity can cause a security to stop trading just by placing orders, you can guarantee someone will take advantage of it.

Step through the images below to see all 50+ occurrences of trade halting not caused by trades.

One of the more interesting ones shows that there was a series of orders put in right before the algo went wild. We have labeled this the "Trigger".

Here you can see it by itself on the security FLAG, which by itself triggered the halt before the algo could go full bore.
