A dash means the release did not state a figure we could extract, not that the figure is zero. Penalty and disgorgement are stored separately so aggregates across the library do not double-count the same dollars.

What is alleged to have happened

This library tags the matter as wash trading, based on the conduct the regulator describes. Each tag links to a page explaining how that technique works, what statute it engages, and what penalties comparable actions have attracted. The tagging is ours, not the regulator's: agencies charge statutory provisions, not technique names.

Non-monetary relief recorded: conduct-based injunction.

The release references a parallel criminal proceeding. Where a criminal case exists, the civil and criminal outcomes are recorded separately, because they resolve on different standards of proof.

For the regulator's own account of the facts, read the primary document linked above. This page deliberately summarises the structured record rather than reproducing the release.
