How often AUDUSD's fair value gaps get revisited (measured)
On the 15-minute chart, price came back into a AUDUSD gap within 1 hour on 68.1% of gaps, within 4 hours on 82.9% and within 24 hours on 93.4%. It filled the gap completely within 24 hours on 87.5%.
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 92.8%. 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 85.4%, the fake one on 85.9%.
| AUDUSD | Gaps | Back within 24h | Fake gap within 24h | Fully filled 24h |

| 1-hour | 4,410 | 85.4% | 85.9% | 73.9% |
Testing an FVG entry on AUDUSD
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 AUDUSD 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 AUDUSD is an evening, not a year.
