What Is an LULD Halt?
A Limit Up-Limit Down halt pauses trading when a stock's price moves more than a defined percentage away from its recent five-minute average. The bands are 5% for most large-cap S&P 500 names, 10% for smaller stocks, and 20% for stocks under $3. Most LULD halts last five minutes.
What Does a T1 Halt Mean?
A T1 halt is a regulatory pause pending the release of material news. It has no fixed duration and resumes when the exchange determines an orderly market can be maintained.
