Trading Halt: Regulatory
Trading in a security can be temporarily halted by stock exchanges for a variety of reasons, including upcoming news announcement or there is uncertainty over whether the security continues to meet listing standards set by the exchange. The halt can last from a few minutes to longer periods, potentially extending across multiple trading days. When the primary listing exchange of a security issues a regulatory trading halt, all U.S. stock exchanges and other market centers that trade the security must also halt trading in the security. While the trading halt is in effect, all U.S. market participants are prohibited from trading the stock.
How does a trading halt impact your order?
Your order will be accepted, but it cannot be executed until the trading halt has been lifted and trading resumes. If trading in an underlying security is halted, all trading in its options will be halted as well.
