City of London





Fit-out Contractor:



The London Metal Exchange (LME) is the world centre for industrial metal trading, with more than three quarters of global nonferrous metal futures business taking place on its three trading platforms. LME prices are used as the international reference price and both metal and investment communities rely on it to transfer or take on risk, 24 hours a day.

In 2012, the LME was acquired by Hong Kong Exchanges and Clearing Limited (HKEX). It is a vibrant futures exchange and has close links to industry, serving as a respected hedging venue with a trusted reference price.

The project brief:

In 2016, the LME unveiled its newly built ‘Ring’, the London Metal Exchange’s openoutcry trading floor, set in the heart of the City of London at 10 Finsbury Square where it relocated to earlier in the year.

proAV was commissioned by AV specialist consultant, CMS, to equip the LME’s new building with a world class, integrated audio visual solution across the iconic Ring trading floor facility. The focus was on delivering the industry’s most dynamic display technologies and audio systems available in the market.

proAV delivered a future-proofed, integrated AV solution that has delivered an outstanding and technically innovative scheme that will support the time-critical work of LME traders.

The key AV technologies that feature within the LME Ring include the following:

  • 2 SCT LED Peony 2.6mm pitch 4.5m wide x 1.5m high to display trading prices
  • 2 55” Samsung LED large format display wall in 5x1 configuration
  • Omnivex digital signage and content management system for distribution across display screens, including complex software infrastructure for content playback
  • 7 PCs to gather content and data streams and local PCs
  • IPTV distribution system boxes
  • Crestron DM infrastructure, including Crestron 32x32 matrix switcher, Matrox video processors for compression, scaling, image manipulation and display onto video walls
  • Main rack with operator keyboards and mice to switch across all PCs
  • 2 55” preview monitors within the control room
  • Bose sound system
  • Professional audio system, including Bose sound, Polycom SoundStructure audio management system, JBL monitor speakers within the control room and Clearcomm talkback system for communication with between trading floor and control desk operators

Challenges and innovations

The LME is a fast-paced, time-critical environment that called for a raft of leading-edge audio visual systems to ensure the rapid dissemination, communication and display of real-time information to the trading floor. The complexity of this AV infrastructure demanded that proAV worked closely with allied contractors to complete this AV project and maintain the integrity of all technical elements, including IT networks, data stream connectivity, etc. that was delivered by other teams.

In terms of innovations, the star product on the LME project was, without doubt, the stunning SiliconCore Technology (SCT) Peony video wall. proAV conducted research and provided a series of demonstrations of competitive products, but it was clear the SCT Peony represented the most energy efficient and cost-effective way to deliver content and data to our client’s operations.

Delivering a resolution of 147,000 pixels per square metre, each 5m screen delivers a true Full HD resolution with brightness up to 2000 nits, ensuring the Peony was the most suitable digital signage product for the LME trading Ring.

A powerful support services solution

As data streamed from the trading floor and other third party sources is live and volatile, it was essential that the LME’s systems remain fully operational and that data integrity is maintained throughout its core hours. The proAV VNOC Technical Service Desk uses a secure Citrix web portal, which allows the support team to access support PCS and Omnivex service to the primary systems, including LED video walls, LED monitor wall, Crestron control and switching and Axis IP cameras. In addition, Max Remote Management provides monitoring and reporting support including essential restarts in the event of failure. 

The Service Desk Team completes regular remote monitoring checks in parallel with the client’s onsite team. All morning checks are recorded via proAV’s Customer Service Department Ticket system, Microsoft Dynamics, for total accountability. 

Other secondary diagnostic software installed on support PCs is connected to the Citrix for second and third line support, incorporating Crestron Toolbox, Polycom Sound Structure, Putty, VNC and Clear-Com FreeSpeak applications.

Now complete, the LME Ring is delivering numerous advantages, including:

  • Engaging digital signage and IPTV to disseminate, distribute and display realtime trading information and data to traders and staff at the Ring
  • The latest display technology and digital signage software system that delivers a more insightful, mission-critical experience
  • A powerful support maintenance contract provided by proAV to ensure real-time monitoring, recording and third and second line support for various applications
