ECC will extend its Trading Limit service for Clearing Members (CM) by introducing a new Risk Limit check for trades registered via STP starting on 31 May 2017. This improvement will offer CMs the opportunity to manage the customer specific daily risk of trades to be registered at the respective market via STP. From 16 May - 29 May 2017 ECC will offer a Shadow Run phase for CMs to get to know the new limit feature. In this Clearing Circular, we would like to provide information regarding the new limit functionality, the limit maintenance procedure, and the prerequisites for participation.
