Reg NMS

Regulation National Market System (Reg NMS) is a set of rules established by the U.S. Securities and Exchange Commission in 2005 to improve the efficiency and fairness of the trading in stocks. Its main goals are to ensure that investors receive the best possible prices when buying or selling shares and to promote competition among different trading venues. Reg NMS includes rules like the Order Protection Rule, which helps prevent “trade-throughs,” ensuring that trades occur at the best available prices across all platforms. Overall, it aims to create a more transparent and orderly market for investors.
