Alpha trading platform moves to TMX Quantum™

April 29, 2013 (TORONTO) – TMX Group today announced the successful migration of Alpha to TMX Group's proprietary trading engine, TMX Quantum. As part of TMX Group's overall integration plan, Alpha now operates on the same platform as Toronto Stock Exchange, TSX Venture Exchange and TMX Select.

"We continue to work to enhance the value of trading on our equity markets with the incorporation of Alpha into our diverse suite of products," says Kevan Cowan, President, TSX Markets and Group Head of Equities, TMX Group. "Shifting Alpha's trading system from external providers to TMX Group technology and data centres provides customers with operational and service efficiencies. This move also represents an important step in the integration of TMX Group following the Maple acquisition."

TMX Quantum XA™ Update
TMX Group today also provided an update on the performance testing and planned launch of its next generation equity trading technology, TMX Quantum XA.

TMX Quantum XA is based on hardware acceleration technology and designed to provide TMX Group equity trading customers with dramatically enhanced speed and capacity as well as more efficient order processing. Testing in the production environment achieved a twenty-fold reduction in median latency (measured at the network edge) to sub-100 microseconds on order executions.

"We are very proud of the successes achieved in testing as we move into the final stages of preparation for TMX Quantum XA implementation," said Brenda Hoffman, Chief Information Officer, Group Head of Technology, TMX Group. "Our equity trading clients will benefit significantly from the performance enhancements and broadened functionality"

TMX Select will be the first TMX equity marketplace to migrate to TMX Quantum XA. Symbols on TMX Select will be migrated onto TMX Quantum XA over three phases commencing Monday July 29, 2013. The migration of Toronto Stock Exchange, TSX Venture Exchange and Alpha onto TMX Quantum XA is scheduled to begin mid-2014.
