What does 'best execution' mean in trading?

'Best execution' refers to the duty of a broker or trader to execute customer orders in the best possible manner, which encompasses various factors including price, speed, and the likelihood of execution. This obligation ensures that customers are getting the most favorable terms when their trades are placed, considering not only the execution price but also the quality of service related to the order execution process.

Traders must consider multiple execution venues and assess the overall trading environment to ensure that they are fulfilling their responsibility to customers. This may involve seeking the best available price, the most timely execution, and overall cost efficiency, weighed against the possibility of execution, which can enhance the client’s experience and satisfaction with their trading outcomes.

Understanding 'best execution' is critical for maintaining compliance with regulations and serving clients effectively in the securities industry.
