Pursuant to MiFIR the term 'buying and selling interests' is to be understood in a broad sense and includes orders, quotes and indications of interest.


The term is widely used for defining multiple MiFID II/MiFIR institutions, among others the concept for multilateral systems like:


regulated markets,


multilateral trading facilities (MTFs), and 


organised trading facilities (OTFs);


as well as other pieces of legislation, like REMIT (see for instance REMIT definition for organised market place or organised market).
