In 2006, a new market model was implemented for the Brussels options market. This improved market model provided a new liquidity provider system and was based on the Amsterdam ELPS scheme. As of 13 September 2010 a full harmonisation of the Rules, functionalities, corporate action handling and operational procedures for the Euronext Amsterdam and Brussels Derivatives Markets has come into effect (Brussels’ notice BRU10-01).

ELPS Brussels is characterised by the presence of two types of Liquidity Provider, Primary Market Makers (PMM) and Competitive Market Makers (CMM). PMMs have obligations across all series in all assigned maturities within the classes to which they have been assigned, while CMMs have obligations in only a limited number of series, in the Near The Money Area, in each class to which they have been assigned.

All Brussels traded contracts (classes) are grouped into class combinations (ECCs). PMMs and CMMs are selected for a specific class by meeting several obligation levels. During the selection procedure applicants are invited to subscribe to the level of obligations they are willing to accept for a position of PMM or CMM in the relevant ECC. NYSE Liffe subsequently evaluates the subscriptions and appoints the required number of PMMs and CMMs based on obligations and priority rules. In principle, ELPS contracts last for one year and all ECCs are re-selected every year (October).
