MiFID II Preparedness Update

MiFID II implementation may significantly affect investors’ ability to source dark liquidity effectively. Broker crossing networks will disappear, and certain types of dark trading will be mostly restricted to midpoint. If triggered, the introduction of double volume caps will limit certain dark trading volumes per stock to 4% in a single dark pool and 8% across all dark pools. The double volume caps are likely to result in six-month dark trading suspensions for many stocks, increasing market complexity around trading suspended stocks and tracking the status of each stock.
