According to FINRA, Lonny Miller has been barred from association with any FINRA member in all capacities for refusing to appear for on-the-record testimony requested by FINRA.

The investigation concerned Miller's trading activity in a personal account held away from his member firm. The account generated an alert through FINRA's cross-market surveillance system, which monitors trading patterns across different markets to detect potential violations such as insider trading or market manipulation.

When surveillance systems flag unusual trading patterns, FINRA investigates to determine whether violations occurred. Miller's personal account activity triggered such an alert, but his refusal to provide testimony prevented FINRA from determining the nature and legality of his trading.

Securities professionals are required to disclose outside accounts and cooperate with regulatory investigations into their trading activity. Miller's refusal to do so resulted in his permanent removal from the industry.

This case illustrates that FINRA actively monitors trading across markets and investigates suspicious patterns. Investors benefit from this surveillance, which helps detect and deter market manipulation and insider trading that can harm ordinary investors.
