What does the top gap mean?

The term "top gap" can refer to various contexts, but generally, it signifies a space or difference between two entities at the uppermost level. In finance, it often describes a price gap in stock trading where the opening price exceeds the previous day's closing price. In other contexts, such as in design or construction, it may indicate a physical separation or allowance at the top of a structure or element. Understanding the specific context is crucial for a precise interpretation.
