US Equities Daily SSR Circuit Breakers
GET/api/v1/data/us-equity-ref/eq-ssr-circ-break
The U.S. Equities Daily SSR Circuit Breakers dataset provides daily reference information on U.S. equity securities subject to the SEC Short Sale Rule (SSR), also known as Regulation SHO Rule 201. The SSR is triggered when a security experiences a significant intraday price decline (-10%), after which short sale executions are subject to price test restrictions. Once triggered, the rule restricts short sales to prices above the current National Best Bid (NBB) for the remainder of the trading day and the following trading day. This dataset identifies securities for which the SSR circuit breaker was in effect, enabling users to account for regulatory trading constraints in execution logic, compliance monitoring, and historical analysis. Data is published on a daily basis and is designed to support institutional trading systems, risk controls, and post-trade analysis involving short sale activity.
