Self-Trade Prevention Functional Overview v1.4 Derivatives

Self-Trade Prevention (STP) has been introduced on Euronext’s Markets to allow Member Firms performing
specific types of activities (e.g. Market Makers) to avoid trading with themselves.
The STP mechanism allows customers to avoid unintentional self-trading that results from the matching of
two opposite orders1 on the same instrument, of the same Member Firm (i.e. with the same Member
Code). The mechanism applies to orders that are submitted via private messages (SBE or FIX) with specific
Account Types.
In the event that two opposite orders belonging to the same Member Firm, and applicable account type,
would match against each other, the mechanism cancels either the resting or the incoming order,
depending on the STP Type chosen.
If STP Type chosen is “Cancel Resting”, then the system enters the incoming order of the possible match,
into the central order book.
If STP Type chosen is “Cancel Incoming”, then no changes occur in the central order book and the incoming
order is rejected.

Exchange For Physical - Functional Overview - v1.3 Derivatives

An Exchange for Physical (EFP) is a transaction involving the simultaneous exchange of a futures position for a basket of shares.

EFPs based on index futures are transactions made on the basis of the difference between the index futures price and the spot price of the index. Currently, the futures leg of these transactions can be reported on Euronext’s Basis Trade Facility, with reference to a cash leg. Euronext’s new Exchange for Physical Facility enables members to trade EFPs on the CAC 40® and AEXIndex® by simultaneously exchanging index futures for the corresponding basket of underlying component securities of the index. The new EFP solution will be available for trading in a regulated environment by means of a transparent central order book supported by a liquidity-providing scheme. Trading of EFPs takes place by means of a fully automated straight-through-process, eliminating operational burdens and facilitating post-trade reporting obligations. In addition, it reduces execution risk thanks to the guarantee of the central counterparty.
