The short version
CRTLAB measured every fair value gap on NAS100 from 2022-07-01 to 2026-11-06: 16,258 on the 15-minute chart (about 13.1 a day) and 4,192 on the 1-hour. Below is how often price came back to them, against a fake gap drawn the same distance on the other side, and a chart that opens with NAS100's FVGs already marked so you can test your own entry.
How often NAS100's fair value gaps get revisited (measured)
On the 15-minute chart, price came back into a NAS100 gap within 1 hour on 65.8% of gaps, within 4 hours on 81.4% and within 24 hours on 92.6%. It filled the gap completely within 24 hours on 86.9%.
The control matters more than the headline: a fake gap the same distance on the other side of price was reached within 24 hours on 93.5%. When the real gap and the fake one are hit about as often, the revisit is mostly just price moving around, not the gap pulling it back. On the 1-hour chart the real gap was revisited within 24 hours on 85.0%, the fake one on 86.1%.
| NAS100 | Gaps | Back within 24h | Fake gap within 24h | Fully filled 24h |
|---|---|---|---|---|
| 15-minute | 16,258 | 92.6% | 93.5% | 86.9% |
| 1-hour | 4,192 | 85.0% | 86.1% | 73.1% |
Testing an FVG entry on NAS100
A count of revisits is not a strategy. What decides it is your entry inside the gap, your stop and the session you trade, and those are the parts only a replay can test. Open NAS100 with fair value gaps drawn, hide the future, and step candle by candle: mark each gap you would take, place the stop and target, and let the journal keep score. A hundred trades on NAS100 is an evening, not a year.
