US Equities Trading Halts
The U.S. Equities Trading Halts dataset provides comprehensive reference information on trading halt events affecting U.S. exchange-listed equities. It consolidates halt activity across all U.S. equity exchanges, delivering a unified view of market suspensions and resumptions. Each record includes the halt reason code, halt initiation timestamp, resumption timestamp, and security-level metadata, enabling precise measurement of halt duration and clear attribution of regulatory or exchange-initiated actions. The dataset captures a wide range of halt scenarios, including regulatory halts, volatility-related pauses, news-pending halts, and operational interruptions. This dataset is designed to support market event analysis, trading system controls, compliance monitoring, and historical research, where accurate identification and timing of trading halts are critical.
