How often USDJPY's fair value gaps get revisited (measured)
On the 15-minute chart, price came back into a USDJPY gap within 1 hour on 69.8% of gaps, within 4 hours on 83.8% and within 24 hours on 93.5%. It filled the gap completely within 24 hours on 87.7%.
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 93.0%. 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 84.9%, the fake one on 85.4%.
| USDJPY | Gaps | Back within 24h | Fake gap within 24h | Fully filled 24h |
|---|---|---|---|---|
| 15-minute | 17,047 | 93.5% | 93.0% | 87.7% |
| 1-hour | 4,140 | 84.9% | 85.4% | 73.2% |
Testing an FVG entry on USDJPY
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 USDJPY 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 USDJPY is an evening, not a year.
