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.
