Cboe Large In Scale Service

Cboe Large in Scale (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 IOI to the wider market.

Pan-European Block Trading Platform

MIFID II buy-side demand has led to more innovation of block trading platforms. In turn, this has led to higher volumes that has helped the buy-side find natural contras. Cboe LIS is the fastest-growing block venue in Europe with trading available in more than 6,000 symbols across 17 major European markets including equities, depositary receipts and ETFs.

Access and Seamless Integration

This service is powered by proven software used by the BIDS ATS, combined with the Cboe Europe exchange infrastructure required for trade execution, clearing and settlement. Cboe LIS is fully compliant with MiFID II regulations. The BIDS Trader interface is seamlessly integrated into buy-side order management systems (OMS), with Cboe sell-side participants also able to enter IOIs through FIX connections.

How it works

  1. IOIs submitted to the Cboe LIS system to identify potential matches.
  2. The platform interacts with buy-side and sell-side to firm up the IOI.
  3. A Designated Broker is selected by the buy-side trader to execute the transaction.
  4. The trade is executed on-Exchange through the Cboe Recognised Investment Exchange.
  5. The trade is sent to clear under Cboe's interoperable model and reported to the Designated Broker via a drop copy.
  6. The trade is reported through the Cboe CXE market data feed as an off-book, on-Exchange trade in real time.
