There have been several anti abuse updates since our last post on the topic here:
The UK’s Financial Conduct Authority (FCA) has published this new “Market Watch” newsletter, which provides some new examples of behaviours that would be considered market manipulation and therefore a breach of MAR. The behaviours are “flying” and “printing”, the practice of giving the impression of orders placed or trades executed at erroneous prices. The misleading prices may be provided using any mechanism, be it screen, chat, telephone or otherwise.
In the US, many new cases are being pursued by regulators and exchanges, as reported here on the Wall Street Journal web site. Many of these cases involve “spoofing” and similar activity. There have been several exchange based fines including this one on Nymex and this one on Comex. The DCM blog, found here, lists several more.
