See here for a post on Finextra by Magnus Alquist about how to prepare for MAD II/MAR. (The new version of the Market Abuse Directive)

For those in the energy industry, REMIT will have similar potential consequences, although the degree to which market participants implement surveillance technology remains to be seen. That debate will start to hot up as the implementing act comes.

MAD II and MAR will also have consequences for the industry for many types of trade not covered by REMIT.
