Thomson Reuters is to suspend a closely-watched data tool that tracks equities trading on exchanges and other venues globally, after issues with the accuracy of the product emerged last month.
The data vendor confirmed to Financial News that its European Market Share Reporter, or EMSR product, would be suspended this afternoon. It is expected to be fully closed by Monday morning.
It said it expected to a release a "new proprietary and equivalent capability" in the first quarter of 2015 and would communicate with its users in due course on the exact timeframe.
The service provides market share statistics from competing equity venues across Europe, North America and Asia-Pacific. It has a wide customer base and is often cited in journals, independent reports and by regulators, including the European Securities and Markets Authority. The data was used by a number of firms to support their responses to an Esma consultation on Mifid II that was held over the summer.
