Japanese Yen 6J

Historical statistics for Japanese Yen over 23,304 observations, from 2010-06-07 to 2026-09-16. Every table shows its sample size (n) next to the percentage.

What sets this instrument apart

  • The gap between one day's close and the next day's open fills in 6J between 76.8% and 99.2% of the time depending on the day. In a contract trading nearly 24 hours that gap is small, which is why it closes so often: it is not a tradable edge.
  • After three or more days in the same direction, 6J keeps going that way 48.4% of the time (n = 967). The idea that 'after three days it turns' gets checked here, not assumed.

n = 3,981 · 2010-06-07 to 2026-09-16 · exchange data

Session colour = close versus the same day's open. It does not measure whether the close held beyond the broken level. A day that breaks both sides counts in both columns.

Gap fill between calendar days

n = 2,650 · 2010-06-07 to 2026-09-16 · exchange data

Here the gap is measured between the close and the open of whole calendar days, not against the regular session. In a contract trading nearly 24 hours that gap is small and fills far more often.

How the day closed, by day of the week

n = 4,218 · 2010-06-07 to 2026-09-16 · exchange data

Close versus the same day's open. If both columns sit near 50%, the day of the week on its own says nothing: that is the most common result and also the most useful to know.

After an inside day, does it break the prior range?

6J

Monday75.4%24.6%702

n = 4,034 · 2010-06-07 to 2026-09-16 · exchange data

Inside day = its high and low fit within the prior day's range. Breaking out is the norm; what informs is how far this instrument sits from that norm.

How close the day's range is to its average

n = 4,217 · 2010-06-07 to 2026-09-16 · exchange data

Measures whether the next day closes in the same direction as the streak. Mostly useful for checking whether 'after three days it turns' holds for this instrument.
