What are Trading Halts?
A trading halt is a temporary suspension of trading for a particular security or securities at one exchange or across numerous exchanges. Trading halts are typically enacted in anticipation of a news announcement, to correct an order imbalance, as a result of a technical glitch or due to regulatory concerns. When a trading halt is in effect, open orders may be canceled and options still may be exercised.
Below is a list of the Types of trading halts and their associated codes.-
