I disagree and here is a link to prove it. It is not just the close but the previous day's high or low that forms the gap. Not just the close.

stockcharts.com

Gaps form when opening price movements create a blank spot on the chart. Gaps are especially significant when accompanied by an increase in volume.

An up gap forms when a security opens above the previous period's high, remains above the previous high for the entire period and closes above it. Up gaps can form on daily, weekly or monthly charts and are generally considered bullish.

A down gap forms when a security opens below the previous period's low, remains below the previous low for the entire period and closes below it. Down gaps can form on daily, weekly or monthly charts and are generally considered bearish.

And here also from clearstation.com explanation of a gap up. Same thing. It's from previous day's high not the close.

clearstation.etrade.com
"Gap Up occurs when a stock opens above the high of the prior day and trades above this price level all day long. This results in a 'gap' in the price graph."
