A halt is a temporary suspension of a security or securities, enacted and enforced by one or numerous exchanges for the duration of the suspension. A security halt is most often caused by rapid and irregular movement in stock price, when the stock price of a security moves outside a pre-determined price band long enough to halt the security. Halts commonly last around 5 minutes, however in some cases halts can last longer than 5 minutes. No trades will take place during the duration of a halt.
