Instinet Incorporated, the wholly-owned execution services arm of Nomura Group, has announced the successful integration of PureStream ATS into Instinet’s BlockCross UI application.

This strategic collaboration allows BlockCross users to seamlessly access PureStream’s innovative “streaming block” liquidity directly from their existing desktop workflow.

“The integration of PureStream into Instinet’s BlockCross application is a natural evolution of our mission to provide clients with the most sophisticated tools for liquidity discovery,” said Gerry Milligan, President and Head of the Americas at Instinet LLC. “By combining BlockCross’ access to high quality mid-point Block liquidity with PureStream’s unique streaming protocol, we are giving our clients a powerful new way to execute large orders with greater efficiency.”

Armando Diaz, CEO of PureStream Trading Technologies said, “By collaborating with Instinet to bring this capability to the BlockCross community, we are expanding the reach of streaming liquidity to provide more execution choices for the buy-side that complement algorithmic execution.”

The PureStream integration is available immediately to all BlockCross clients that have been upgraded to version 10. Any PureStream order interaction is done on an opt-in basis.
