Regulation NMS

Regulation NMS (National Market System) is a set of rules established by the U.S. Securities and Exchange Commission in 2005 to enhance market transparency and efficiency. It aims to ensure that investors receive the best possible prices for their trades across different stock exchanges. Key components include the requirement for market participants to execute trades at the best available prices and to make stock quotes available to everyone. Overall, Regulation NMS promotes fair competition among trading venues and helps protect investors by increasing their access to information and improving transaction execution.
