Network routing issues within BATS network infrastructure resulted in sporadic Member disconnects to TCP based order entry and market data feeds which were primarily resolved at approximately 9:20AM ET. After that time, certain Members continued to report isolated issues on specific TCP ports. BATS worked directly with the few remaining impacted Members on their port specific issues and as of 10AM ET, all issues were resolved. Please contact the BATS Trade Desk or your Director of Sales with any questions. Thank you for your continued support of BATS.

All BATS systems are operating normally. Please contact the BATS Trade Desk or your Director of Sales with any questions. http://www.batstrading.com/alerts/system/2013/#9 Fri, 25 Jan 2013 14:19:40 -0500 http://www.batstrading.com/alerts/system/2013/#9 Dear Member, Please be advised that, as announced January 9, 2013, BATS has determined that upon an NBBO update on BATS' BYX Exchange, BZX Exchange and BATS Options, there are certain cases where the Matching Engine will allow for a trade through or an execution of a short sale order at a price that is equal to or less than the NBB when a short sale circuit breaker is in effect under Regulation SHO. These cases result from the sequencing of certain required events in the Matching Engine related to re-pricing and sliding orders in response to the NBBO update. REVISED (1/25/2013): After further analysis, BATS has determined that more than 97% of the originally reported executions were not trade throughs under Rule 611 of Regulation NMS because they involved trades through quotes that had existed for less than one second or were priced below $1 and were within $.01 of the protected quote. Consequently, less than 12,000 trades have been confirmed to constitute trade throughs under Rule 611 across all three BATS US markets during the affected period. The updated numbers are below. In the first case, a visible order that is posted and has been price slid can execute at a price that trades through another market center's protected quote if that away market center locks the displayed price of the BATS order and then BATS receives another order that crosses the working price of the resting order. In the second case, the system was programmed to allow non-displayed peg orders to re-price in response to a change in the NBBO prior to sliding previously booked contra-side hidden orders that now cross an away market center. As a result, it is possible that in response to a change in the NBBO, the price of a resting hidden order could be crossing the NBBO momentarily and an execution could occur at that crossing price against a peg order that is re-priced in response to the NBBO change, resulting in a trade through. This particular issue can also result in a short sale order executing at a price that is equal to or less than the NBB while a Regulation SHO circuit breaker is in effect. These system compliance issues have resulted in the following incidents:Trade Throughs=============BATS Options(02/26/10 - 01/24/13)Average Daily Incidents: 0.4Total Incidents: 300 BYX Exchange(10/15/10 - 01/24/13) Average Daily Incidents: 0.6Total Incidents: 348 BZX Exchange(10/24/08 - 01/24/13)Average Daily Incidents: 10.5Total Incidents: 11,215 Regulation SHO Incidents====================BYX Exchange(02/28/11 - 01/04/13)Total Incidents: 174 BZX Exchange(02/28/11 - 01/04/13)Total Incidents: 3,489 BATS deployed a permanent change to correct this system issue on January 25, 2013, in conjunction with its associated SEC rule filing.
