Trading System

ISE Xetra is the electronic trading system for equities and ETFs and results from our strategic technology partnership with Deutsche Börse AG.

Xetra’s performance and functionality has made it one of the world’s leading trading systems. Its built-in back-up facility strengthens its resilience guaranteeing close to 100% service levels for our trading members.

Continuing the successful strategic technology partnership with Deutsche Börse AG, the ISE will migrate its order book to the next generation T7 trading platform on Monday, 17 July, 2017. ISE T7 will ensure that the ISE continues to enhance its trading architecture for the benefit of members by providing access to a new, world class platform.

The ISE will also migrate its off order book on exchange trade reporting functionality to a new system, 'ISE OBOE', on Monday 4 December. ISE OBOE will be fully MiFID II compliant and the ISE recently confirmed these arrangements for on exchange trade reporting in the Irish market under MiFID II.
