Transaction Network Services (TNS) will now support the Long-Term Stock Exchange’s (LTSE) new range of MEMOIR market data feeds as part of its expanded market data offerings.
MEMOIR (Member’s Exchange Order Information Record) is a proprietary multicast data protocol developed by MEMX now available for LTSE traders via their new trading system.
TNS provides access to LTSE’s Depth, Last Sale and Top of Book feeds
Tom Lazenga, General Manager, TNS Financial Markets, said: “TNS enables cost-effective access for the LTSE trading community, and we are delighted to be extending this to cover LTSE’s Depth, Last Sale and Top of Book feeds.”
LTSE’s full range of multicast market data is now accessible through TNS’ ultra-low latency infrastructure for global order routing, which delivers real-time information and includes all US equities exchanges.
TNS offers a 125-strong point-of-presence footprint specifically designed and engineered to address the needs of financial market participants worldwide. Its range of connectivity, colocation, cloud, market data, and VPN solutions is within its Infrastructure-as-a-Service (IaaS) portfolio.
TNS launches full-stack market data management in EMEA
In April, the provider of connectivity and market data expanded its US strategy of full-stack market data management to the EMEA region, meaning it can now deliver market data services across the entire trading infrastructure stack.
The ‘one-stop-shop’ offering is the result of the acquisition of West Highland Support Services, a financial market data solutions provider.
TNS and West Highland services are now available to EMEA customers as a single, combined offering, including connectivity, monitoring, and consulting to financial markets participants. TNS can be leveraged as a single point of contact to manage the full scope of all consolidated feeds and normalized data solutions.
Market data is often one of the top-two spend categories for most trading organizations, but TNS promises cost savings and economies of scale across every element of market data related spend and support, including hosting, connectivity, middleware distribution, market data usage, and incident management.
To lead strategic sales in the EMEA region, TNS has hired Ben Myers, an experienced executive within the financial markets and trading technology space with more than 15 years working at leading names such as IBM, Thomson Reuters, and most recently ICE Data Services.
