Turquoise offers London Stock Exchange hosted members free connectivity and upgrades trading platform

Turquoise announced today that a free ultra fast link between the London Stock Exchange’s data centre and Turquoise’s trading system is available for use by clients with hosted systems in the London Stock Exchange Group co-location facilities, creating a single virtual location for the Group’s platforms.

The link will carry market data from Turquoise to market participants and allow order entry back to Turquoise, with extremely low latency and at no additional cost.

Members of the London Stock Exchange providing sponsored access services, with pre-trade risk control systems deployed at the Exchange’s data centre, can now include access to Turquoise in their offering.

Turquoise also revealed that it has upgraded its current matching platform to improve performance, taking its median system latency below 800 micro-seconds and adding substantial additional capacity.

The upgrades to the current platform, soon to be replaced by Millennium Exchange, were undertaken to handle both growing volumes in the non-display Midpoint Book, which has become the second largest such venue in Europe, and to provide additional capacity to new market makers joining Turquoise.

David Lester, CEO of Turquoise, said:

“This low latency link gives every member firm co-located at the London Stock Exchange’s data centre free, virtual access to Turquoise, helping our group clients trade on Turquoise in a simple and cost effective manner. Turquoise will further differentiate itself from competing venues later this year when we migrate to Millennium Exchange, offering synergies for clients who choose to access both the London Stock Exchange and Turquoise through shared co-location, connectivity and common trading interfaces.”
