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 Euronext Dublin migrated to the next generation T7 trading platform on 17 July 2017. ISE T7 further enhances the performance, latency and capacity our equity market offering and provides synergies for international firms with existing T7 connectivity to cross-connect and trade equities on Euronext Dublin.

Trading System

On 17 July 2017 Euronext Dublin 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. For further information on the MiFID II aspects of ISE T7, please refer to the 'MiFID II' section below.

On 18 June 2018, ISE T7 was further enhanced with the implementation of Release 6.1. Release 6.1 introduced enhancements to the trading and reference data interfaces. Further information is contained in the ISE T7 Release 6.1 Release Notes.

ISE OBOE, the system for the submission of off order book on exchange trade reports was also launched on Monday 4 December 2017. ISE OBOE is fully MiFID II compliant.

Documentation relating to ISE T7 Release 6.1 and ISE OBOE is available below.


The new order entry fields required by MiFID II were introduced with T7 Release 6.0, and became mandatory on 3 January 2018.

In addition, the requirement to upload algo certificates and the short code / long code mapping file also became a mandatory requirement from 3 January. The upload can be done via the Xetra member portal or via SFTP. The ISE implemented the MiFID II tick sizes from commencement of trading on Tuesday 2 January 2018.

Full details of the new fields and the file uploads are contained in the Release Notes and the ISE T7 Market Model, available for download from the ISE T7 Release 6.0 Documents section. Information is also contained in the following document:
