(119)It is appropriate to set up a non-exhaustive list of high-level circumstances where significant infringements of the rules of a trading venue, disorderly trading conditions or system disruptions in relation to a financial instrument may be assumed, thus triggering the obligation for the operators of trading venues to immediately inform their competent authorities as set out in Articles 31(2) and 54(2) of Directive 2014/65/EU. For that purpose, reference to the ‘rules of a trading venue’ should be understood in a broad sense and should comprise all rules, rulings, orders as well as general terms and conditions of contractual agreements between the trading venue and its participants which contain the conditions for trading and admission to the trading venue.
