Warning indicators are signs or signals that suggest a potential problem or danger. They can be visual, auditory, or even behavioral cues that alert individuals to take caution. For example, a flashing red light on a traffic signal indicates that vehicles must stop, while a loud alarm may signal a fire or security breach. In various fields, such as finance or health, warning indicators help identify risks. In finance, a sudden drop in stock prices can serve as a warning that investors should reassess their strategies. In healthcare, symptoms like chest pain may indicate a serious condition requiring immediate attention.
