Self-Trade Prevention Functional Overview - v2.0 Optiq Order Entry

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 orders on the same instrument, of the same Member Firm (i.e. with the same Member
Code). The mechanism applies to orders and or/quotes 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, the incoming order or both
depending on the STP Type chosen.
