Generally, either you or your brokerage firm may close your brokerage account at any time. The specific steps you will need to follow to close your account are usually found in the terms and conditions of your brokerage account agreement. In addition, these terms and conditions generally specify when and how your brokerage firm may close your brokerage account at its own discretion. If you have any questions regarding the terms and conditions in your brokerage agreement, please contact your brokerage firm.
