TNS Launches Market Data Optimisation Portal

Transaction Network Services (TNS) has announced an upgrade to its TNS Data Usage Optimizer (DUO) with the launch of an interactive customer portal, that allows clients to monitor their market data usage.
Building on the launch of DUO in late 2024, the new interface offers firms direct, on-demand access to the portal to analyse market data subscriptions, identify unused services, and eliminate unnecessary spend.
The firm says that market data is one of the largest operational expenses for financial firms, but adds that costs can be “notoriously difficult to manage”. To solve this issue, it says the new portal turns complex, raw data files from vendor entitlement systems into an actionable dashboard, allowing firms to quickly pinpoint and eradicate non-essential costs.
TNS says it has used DUO with global banks and financial firms and in the case of one un-named bank, it identified monthly savings of $60,000 by highlighting unused data feeds.
“Last year we introduced DUO to solve a critical industry problem. Today, we’re putting the power to control market data costs directly into our customers’ hands,” says Tom Lazenga, general manager, TNS Financial Markets. “The DUO portal empowers data managers and desk heads to instantly identify and act on potential savings.
“Our goal with the DUO portal was to make identifying wasted spend as simple as possible,” he adds. “This portal lays the foundation for our product roadmap, which includes automated feed provisioning and support for additional data providers.”
