As market data and volumes increase, stock exchanges and other financial firms are challenged to improve transaction speed while reducing latency. IBM WebSphere MQ Low Latency Messaging combined with IBMís Power Systems platform, provides extremely low latency with high availability and reliability. For stock exchanges and other financial firms, it provides an end-to-end equity stock trading environment including order generation, processing messages at fixed gateways and routing to matching engines within the exchange. IBMís Stock Exchange Reference Architecture Implementation runs an unprecedented 12 times faster than any other exchange. It processes 1.2 million equity trades per second with a round trip processing time of under 400 microseconds. Itís the fastest messaging platform in the world, processing tens of millions of messages per second with latency as low as 7 microseconds, reports Nir Naaman, research scientist and Paul Michaud, architect with IBM Global Financial Markets.
