Article 81

When assessing whether the requirement to immediately inform their competent authorities of significant infringements of the rules of their trading venue or disorderly trading conditions or system disruptions in relation to a financial instrument applies, operators of trading venues shall consider the signals listed in Section A of Annex III to this Regulation.

Information shall only be required in cases of significant events which have the potential to jeopardise the role and function of trading venues as part of the financial market infrastructure.
