The offering sees Trillium’s trade surveillance platform integrate Blue Ocean ATS’s pre and post-trade data to allow clients to monitor trading activity during Blue Ocean’s overnight trading sessions, from 8pm to 4am ET, Sunday to Thursday.
The partnership also makes Trillium Surveyor the first trade surveillance provider to cover overnight trading sessions.
“Being the first to support 24/5 trade surveillance reflects our mission to meet the evolving needs of the global trading community,” said Lisa Balter Saacks, president of Trillium Surveyor.
“As trading hours extend, our commitment to delivering real-time oversight, innovation and speed to market extends right alongside them.”
Through this move, Trillium Surveyor’s institutional and global clients are set to benefit from the flexibility to operate around the clock, while maintaining the same levels of compliance and confidence in a standard trading day.
John Willock, head of strategy and market data at Blue Ocean Technologies said: “Trillium Surveyor’s oversight for 24/5 trading marks an important first for the industry.”
“This partnership aligns with our mission to provide market participants with the infrastructure and safeguards required to trade responsibly around the clock.”
