Free FINRA SIE (Securities Industry Essentials) lesson in Understanding Trading, Customer Accounts and Prohibited Activities. 28 min read, ~4,126 words.

Almost every prohibited activity on the exam comes down to one move: turning an edge in information, a customer's trust or a customer's money into personal gain. A question describes the move and asks you to name the violation.

FINRA Rule 2020 bars members from effecting or inducing any trade through a manipulative, deceptive or fraudulent device. FINRA Rule 2010 demands high standards of commercial honor and just and equitable principles of trade. It catches misconduct that no specific rule names.
