Level Scope › Fair value gaps
Fair value gap inverted
A gap that price closed through, against the gap's own bias. A bullish gap inverts on a close below its floor; the bearish case is the mirror.
What it looks like on a chart
A shaded band over the inverted gap, from the bar that closed through it.

What we measured
We checked the two published definitions against each other rather than assuming: MQL5's break-then-re-enter-then-close variant is strictly nested inside LuxAlgo's simpler one, firing only where LuxAlgo does and later, at a cost of about six points of coverage. Zero exceptions in 298,900 hourly signals.
What it does not claim
We ship the wider one, so you get a superset and the event names which. Two degrees of freedom that no source closes are closed here and labelled: a gap is tracked for a stated span of chart time and then abandoned, and a gap inverts at most once. Close, never wick.
Where the definition comes from
LuxAlgo — the wider of the two published definitions; MQL5's is strictly nested inside it
