Equity Trading - May 2023


In this month’s Equity Trading Newsletter, you will find equity product innovation updates as we plan to (1) launch dark trading and midpoint functionalities, and (2) expand our retail offering for pan-European and US stocks.

Simon Gallagher


Euronext will launch dark, midpoint and dark-lit sweep functionalities on its Central Order Book: a full suite of dark limit orders, peg to midpoint and sweep functionalities for Dark to Lit interactions at 10x lower latency than MTFs.

Euronext will expand its retail offering on the Global Equity Market (GEM) and Trading After Hours (TAH): over 300 pan-European and US shares will be available for trading until 20:30 CET, cleared and settled in Euros, with the same market microstructure and connectivity as Euronext main markets.

1. Dark trading and midpoint functionalities

  • The latency between Euronext and London MTFs has multiplied by ~10 since the migration of Euronext Data Centre from Basildon (UK) to Bergamo (Italy), thus Dark to Lit execution performance is deteriorating on MTFs
  • Euronext will launch dark functionalities allowing participants to source liquidity in both pools (Dark and Lit) within the Central Order Book – at no latency
  • Focus is mainly on execution below Large-In-Scale since two thirds of dark trading in Europe occurs below LIS threshold
  • Full suite of functionalities: Limit orders / Peg to Midpoint / Sweep functionalities for Dark to Lit interactions / Minimum Quantity and Size thresholds (MAQ & MES)
  • Limited market impact on orders executed on the dark book and, thanks to the sweep functionalities, orders can be transferred to the Euronext Lit CLOB with no latency in case of partial or no execution in the dark
  • Expected timeline for the launch is Q4 2023, and in the meantime we welcome your thoughts on the full design of functionalities and the technical implementation.

Focus on latency:

How long does it take for an order sent from London to reach the Euronext Data Centre in Bergamo?

  • From 0.5 milliseconds before the Data Centre move from London to Bergamo in June 2022, to 3-4ms (microwave) or 7-8ms (fibre) today.
  • Euronext will close this gap offering Dark to Lit execution at no latency, within the same CLOB and leveraging on the Data Centre in Bergamo.

  • Dedicated retail offering with 100+ EU and US blue-chips available
  • Trading until 20:30 CET overlapping with US markets hours
  • Same connectivity, microstructure, market surveillance as Euronext main markets – and already migrated onto Euronext's Optiq platform on 27 March 2023
  • 40+ members connected: local retail banks, global brokers and market makers
  • A full revamp of the market will occur in Q3 2023, with a dedicated market making scheme to boost liquidity and an expanded stock universe.
