Euronext offers off-order book on-exchange trading across its financial derivatives markets in Amsterdam, Brussels, Lisbon and Paris.

Customers can execute and report their wholesale business through five facilities:

  • Request for Cross (RFC) Facility
  • Large-in-Scale (LiS) Facility
  • Large-in-Scale (LiS) Prof Facility
  • Guaranteed Cross (GXT) Facility
  • Basis Trading (BAS) Facility

Request for Cross (RFC) Facility

The RFC facility can be used for cross trades with a size below as well as above the Large-in-Scale (LiS) minimum volume threshold. After the RFC is submitted by the RFC Initiator there is a 1 second auction period that is open to all market participants. During this RFC response period other participants (RFC Reactors) may choose to price-join or improve the cross level. After the RFC response period ends the RFC is executed. Depending on the prices of the RFC Reactor responses, one or more RFC Reactors may trade against the RFC Initiator.


  • for all equity and index options listed on the four Euronext Financial Derivatives markets;
  • during contract trading hours.

Large-in-Scale (LiS) Facility and Large-in-Scale (LiS) Prof Facility

The execution of a Large‐in‐Scale (“LiS”) trade is subject to the compliance with minimum volume threshold (variable according to the contract), fair value, and, in the case of LiS Prof, Package composition/ Prof ID.

Basis Trading (BAS) Facility

This facility is for transactions between a basis trade instrument (a correlated security, a basket of securities, a traded contract listed on another trading venue or an OTC instrument) and an appropriate number of offsetting futures in order to trade the difference in price of the two related instruments. A LIS minimum volume threshold applies to one leg but not the related other leg.
