Cboe Large-In-Scale (LIS) Service

Cboe LIS* is an indication of interest (IOI) negotiation and execution platform allowing market participants to trade large blocks of European equities without revealing their identities or IOIs to other users or the broader market. IOIs submitted to Cboe LIS interact in a manner similar to BIDS conditional orders on the BIDS ATS. All trades are executed on-Exchange through the Cboe Registered Investment Exchange (RIE) and are reported through the Cboe CXE market data feed as an off-book, on–Exchange trade in real time.

Cboe LIS European Designated Broker

Institutions trade on Cboe LIS through a designated broker model, which is similar to the sponsored user model offered by BIDS Trading. This model allows institutions to choose from a list of “designated brokers” to clear and settle trades just as if a client traded with them directly. Designated brokers have a pre-existing relationship with an institution and are members of Cboe European Exchange, so they can clear and settle the trade. An institution must select a designated broker prior to submitting a firm order to trade through Cboe LIS.
