The UK’s Financial Conduct Authority (FCA) have issued a consultation paper on MiFID II, which can be found here. The consultation is the first in a series, and mainly covers topics related to secondary trading, such as the operation of venues (RM, MTF, OTF) as well as Systematic Internalisers (SI). It also touches upon related topics such as transparency and reporting, as well as aspects of algorithmic and high frequency trading.
Later consultations will focus on other topics, once the requirements firm up. The consultation closes on 8th March 2016
