  • Order Book Enhancement Programme

We operate a continuous programme of investment ensuring our services are continually enhanced to meet today’s trading challenges and opportunities. Our hidden order functionality will provide richer trading functionality for our SETS, IOB and ITBB order books, enabling customer’s orders to interact with a deep, liquid order book, providing a high probability of execution, whilst minimising information leakage and helping to reduce the total cost of trading.

This phase of the enhancement programme consists of hidden limit orders, hidden pegged orders and minimum execution size.

  • Central Counterparty and Settlement Netting

The Exchange has introduced a choice of CCP for equity trades on the SETS and SETSqx market. Customers can choose to clear their trades through either LCH.Clearnet Ltd or SIX x-Clear AG. It does not matter whether the trading counterparty is using the same or a different CCP.

The approach used is consistent with the European Code of Conduct for Clearing and Settlement peer-to-peer interoperability model.

The CCP service was enhanced on 1 July 2002 to include optional settlement netting. The objective is to allow participants to have just one net settlement per security per day with LCH and x-clear, irrespective of the number of trades they had dealt on SETS.

The CCP service is now available for all automatic executions on SETS and SETSqx.
