Your Broker is Liable for a Failure to Execute
Brokers have a duty to properly and promptly execute customer orders. Failure to execute trades, also known as a failure to follow instructions, occurs when a broker does not execute a trade ordered by a client. Other cases include the failure of the broker to obtain the best possible price during an authorized trade, make the trade in a timely manner, or carry out a pre-specified action at the price the client believes it will be. If a client directs his or her broker or advisor to sell or buy a given security and it is not done, or not done in a timely manner, the broker will be found in violation of his or her duties to the client.
