London Metro Raw Feeds see an extension by McKay Brothers, offering the lowest latency possible
McKay Brothers International (MBI) has announced a significant expansion of its Raw Feeds service in the UK, effective as of July 24, 2025. This move aims to deliver the lowest known latency market data in the London Metro region [1][3].
Expanded Services and Exchanges
The expansion includes the distribution of cash equities market data from the London Stock Exchange (LSE) and Turquoise directly to traders co-located at the Slough-LD4 data center [1]. This builds on MBI’s existing distribution of Cboe EU exchange data (specifically CXE and BXE feeds) at LSE, a service that has been active since 2023 [1].
MBI remains committed to offering the fastest exchange data, ensuring that all market participants have access to the same high-quality, real-time information on a level playing field [1]. The company continues to deliver a range of feeds—Raw, Snapshot, and Signal—tailored to different needs for speed and detail, and offers private bandwidth capacity for clients [1].
Participating Exchanges
The expansion specifically includes the following UK exchanges and trading venues:
- London Stock Exchange (LSE) MBI now distributes LSE cash equities market data via its Raw Feeds.
- Turquoise Market data from this pan-European multilateral trading facility (MTF), operated by LSEG, is also available through MBI’s service.
- Cboe Europe (CXE, BXE) MBI has distributed Cboe EU exchange data at LSE since 2023 and continues to do so [1].
These services are primarily targeted at professionals colocated in the Slough-LD4 data center, a key hub for low-latency trading in Europe.
Broader Context
This expansion is part of a broader strategy by MBI to serve major European financial hubs, including London, Frankfurt, Bergamo, Zurich, and Madrid, with data sourced from leading global exchanges [1]. The company’s offerings cover cash equities, ETFs, futures for metals, interest rates, equity indexes, energy, FX, and crypto [1]. This positions MBI as a critical infrastructure provider for high-frequency and algorithmic trading firms operating in the UK and across Europe.
Francois Tyč, Managing Director of MBI, has expressed excitement about expanding the Raw Feeds in the London Metro region.
Lowest Known Latency Market Data
McKay Brothers London's Raw Feeds remain the lowest known latency market data services in the London Metro area. This expansion further solidifies McKay Brothers London's status as the best provider of ultra-low-latency exchange data across European markets.
