See here for a story on FT.com which reports on issues that the London Metals Exchange have experienced with Suspicious Transaction and Order Reporting (STOR), a requirement for exchanges and many market participants under MAR. The story highlights  issues with  the process that LME followed when submitting STORs, which could be attributable to an unscheduled move occurring at a similar time to the start of the Market Abuse Regulation on 3rd July 2016. As well as exchanges, Professional Persons Arranging and Executing Transactions (PPAET) must submit STORs when appropriate. PPAETS are defined by many to cover a wide group.

The story comes at a time when the market is also seeing increased activity around the enforcement of the anti abuse elements of REMIT.
