DFM brokerage firms are required to ensure that their employees have appropriate professional experience if they are employed to deal with clients or on their behalf. This is because employees interacting directly with clients must possess the necessary skills, knowledge, and experience to provide accurate information, manage client portfolios, and handle client transactions in compliance with regulatory standards. This ensures that clients are protected from potential mismanagement or malpractice and that the brokerage firm maintains a high standard of service.
