Definition
The Order Protection Rule is a provision under the Regulation National Market System (NMS), established by the SEC in 2005, which aims to guarantee that investors receive the best possible execution price when trading securities listed on exchanges. This rule effectively eliminates “trade-throughs,” which occur when an order is executed at a price inferior to the best available quote on another exchange.
Order Protection Rule vs Trade-Through Rule Comparison
| Order Protection Rule | Trade-Through Rule |
|---|---|
| Ensures execution at the best available price | Refers to actions that occur when an order is executed at a price worse than the best available |
| Aimed at preventing poor execution prices for investors | Describes the infringement of the execution price quality standard |
| Enforced by trading venues to maintain fair pricing | Identifies the issue the Order Protection Rule seeks to eliminate |
How the Order Protection Rule Works
-
Monitoring Quotes: Exchanges must monitor quotes on all trading venues for NMS stocks. If any trading venue displays a better price, the executing venue must honor that quote.
-
Best Execution Policies: Trading centers are required to establish robust policies and procedures that ensure compliance with the Order Protection Rule.
-
Audit and Enforcement: Exchanges must regularly audit their compliance with this provision and assure that trades executed reflect top market prices.
