Equity Trading - Irish Equity Liquidity

The leading venue for Irish equity trading

We offer our domestic and international trading members the most efficient marketplace for trading in Irish equities. We run cost-effective and easily accessible trading and post-trade systems in partnership with Deutsche Börse (ISE T7), Euroclear UK & Ireland (CREST) and Eurex Clearing AG (CCP). Our competitive pricing model incentivises our members to increase their trading activity. As a result, we remain the main pool of liquidity for Irish equities.

We are pleased to confirm that the ISE migrated to the next generation T7 trading platform on 17 July 2017. ISE T7 further enhances the performance, latency and capacity of the ISE's equity market offering and provides synergies for international firms with existing T7 connectivity to cross-connect and trade equities on the ISE.

Trading System

On 17 July 2017 the ISE migrated its electronic order book to the next generation T7 trading platform, continuing the successful strategic technology partnership with Deutsche Börse AG. ISE T7 provides members with a low latency and efficient order book for the trading of equities and ETFs.

On 4 December, 2017, ISE T7 was upgraded to Release 6.0, to implement the technical and functional changes to the trading system required by MiFID II/MiFIR.

ISE OBOE, the new system for the submission of off order book on exchange trade reports was also launched on Monday 4 December 2017. ISE OBOE will be fully MiFID II compliant and the ISE confirmed these arrangements for on exchange trade reporting in the Irish market under MiFID II.

Documentation relating to ISE T7 Release 6.0 and ISE OBOE is available below.

Connecting to the Trading Platform

Connection to the ISE T7 platform is possible via the following options with the complete range of the T7 interfaces available:

  • by using their existing T7 connectivity
    If a participant of another T7 market becomes an ISE trading member it can connect to ISE T7 using its existing lines and significantly reduce connectivity costs
  • by ordering separate connectivity
    A broad range of connectivity options exist, including co-location, allowing trading members to choose a connection which suits their particular needs
  • via an ISE-registered service provider
    Service providers can provide trading members with a technical connection to ISE T7 as well as additional services such as front-end software

Members can order connectivity via the Member Section on the Deutsche Börse website:


Full details of the available interfaces, the bandwidth options, and pricing, are available here.
