When a stock moves too far, too fast, the exchange pauses trading
A trading halt fires when a stock moves too far, too fast — or when big news is about to drop. Earnings surprises. FDA decisions. Takeover rumors. NASDAQ, NYSE, and AMEX pause trading, and reopening prices can move sharply in either direction. HaltAlerts notifies you the instant the halt is published, with the halt reason, price, volume, bid/ask, and a 5-minute chart — everything you need to understand what's happening.
