Volatility halts (also known as trading “pauses”) are circuit breakers that trigger 5-minute halts on rapid spikes or dips in the price of a single security.
This rapid change in price must exceed the Acceptable Trading Price Range (ATPR) for a period of at least 15 seconds. This range is calculated as the average price of the previous 5-minute trading period.
ATPR ranges are not universal, and it is important to remember that different stocks will have their own individual ATPR ranges.
