The Corporate, Municipal, and UIT (CMU) system provides all of its customers with RTTM - a single pipeline, a common processing platform, and a standardized message format for the U.S. fixed income markets. RTTM reduces execution and settlement risk as well as costs because it allows customers to maximize the volume of trades that match on trade date, and ensures that trades are locked in and ready for settlement, moments after they've been submitted. It also allows firms to fix any processing problems the same day when an error occurs, rather than waiting for the following morning, as in the previous batch processing system.
