Before Regulation NMS, different trading venues often displayed varied prices for the same security.

Regulation NMS addresses these issues by establishing rules that coordinate trading across multiple platforms seamlessly.
The Core Components of Regulation NMS
Regulation NMS comprises several key rules that collectively enhance market functioning:
-
Order Protection Rule (Rule 611)
This rule requires trading venues to ensure that investors receive the best available price when executing a trade. Essentially, if a security is quoted at a better price on one venue, a broker must route the order there instead of to a less favorable platform. This promotes price consistency and prevents “trade-throughs,” where trades are executed at inferior prices. -
Access Rule (Rule 610)
The Access Rule aims to ensure fair and equitable access to trading venues. It discourages trading platforms from imposing unfair fees or restrictions that could hinder competition. This fosters an open environment where all market participants have a fair chance to execute trades at competitive prices. -
Order Execution Rules
These rules promote transparency in order handling. They require traders to execute orders in a fair and timely manner, reducing the chances of manipulative practices such as quote stuffing or layering. -
