This library records 12 enforcement actions tagged front running. Front running is trading ahead of a customer order to capture the price improvement that order will produce, which breaches a duty owed to that customer rather than falsifying any public price.
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 front running technique page.
