systematic internaliser

an investment firm which, on an organised, frequent systematic and substantial basis, deals on own account when executing client orders outside a regulated market, an MTF or an OTF without operating a multilateral system; The frequent and systematic basis shall be measured by the number of OTC trades in the financial instrument carried out by the investment firm on own account when executing client orders. The substantial basis shall be measured either by the size of the OTC trading carried out by the investment firm in relation to the total trading of the investment firm in a specific financial instrument or by the size of the OTC trading carried out by the investment firm in relation to the total trading in the Union in a specific financial instrument. The definition of a systematic internaliser shall apply only where the pre-set limits for a frequent and systematic basis and for a substantial basis are both crossed or where an investment firm chooses to opt-in under the systematic internaliser regime;
