If you see a "Gap", expect the price to come back and correct the emotion!
When some news event, or, manipulation happens, the price swings to extreme, leaving "gaps" in the price, from the previous day close, to the next mornings open.
Breakaway Gaps are usually closed over time. You see them in a multiday emotion run, or walkdown, where the stock price is trending around, over several months. The retail mindset returns to logic, and fills the gap with the retrace.
