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:
- 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).
