Marking the open enforcement actions

This library records 1 enforcement action tagged marking the open. Marking the open is trading into a market's opening auction or first minutes to move the official opening price, which is thinner and cheaper to influence than the close but still feeds benchmarks and guarantees.

Actions are listed newest first. Each row links to a case page carrying the regulator's own release and, where one was published, the complaint. For how this technique works and what statute it engages, read the marking the open technique page.
