Smart Scanners › Fair value gaps

Fair value gap touched

The event people actually watch for. Forming a gap is common; coming back to one that had stayed untouched is the part the literature builds entries on. Touched means price reached the near edge.

What it looks like on a chart

A shaded band over the gap, from the bar that re-entered it.

Where the definitions disagree

This fires on an event, not on an expectation. Note the tracking horizon in the table above: it is stated in hours of chart time, so it is the same span on every timeframe, and a gap older than it is not tracked.

How often an H1 fair value gap has closed, by the size of the gap in ATR(14). 387,740 gaps across seventeen instruments, 2000-01-02 to 2026-08-24. The gap count is the one at 24 bars; a gap opened near the end of the data has no 48-bar future and drops out of that column.
Gap size	Gaps	Closed within 24h	Closed within 48h
0.00–0.10	82,842	86.6%	90.4%
0.10–0.25	97,807	83.1%	88.0%
0.25–0.50	96,727	77.1%	83.7%
0.50–1.00	75,702	66.8%	76.1%
1.00+	34,581	46.0%	59.5%

Settings, as they are actually applied on each timeframe. A dash means this scanner emits no settings string. Where a number differs by timeframe, that is a span of chart time resolved into bars.
Timeframe	Bars of history it reads	Settings	Events, last 30 days
M15	1080	gap >= 1 ATR, tracked 960 bars (240h; ~94% of touches, measured H1)	481
M30	600	gap >= 1 ATR, tracked 480 bars (240h; ~94% of touches, measured H1)	252
H1	360	gap >= 1 ATR, tracked 240 bars (240h; ~94% of touches, measured H1)	115
H4	180	gap >= 1 ATR, tracked 60 bars (240h; ~94% of touches, measured H1)	41
D1	130	gap >= 1 ATR, tracked 10 bars (240h; ~94% of touches, measured H1)	5
