Wheat ZW
Historical statistics for Wheat over 27,659 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 ZW between 75.3% and 90.0% 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.
- The busiest day is Monday, with an average range of 18.25 points, and the quietest is Friday, with 17.13: a 7% difference worth accounting for when sizing the stop.
- After three or more days in the same direction, ZW keeps going that way 48.6% of the time (n = 1,011). The idea that 'after three days it turns' gets checked here, not assumed.

Breaking yesterday's range and the closing colour
ZW
| Day | Breaks the high and closes green | Breaks the low and closes red | Breaks |
|---|---|---|---|
| Monday | 59.4% | 76.9% | 747 |
| Tuesday | 70.6% | 70.7% | 800 |
| Wednesday | 71.0% | 72.6% | 785 |
| Thursday | 67.4% | 78.3% | 794 |
| Friday | 71.1% | 73.5% | 769 |
n = 3,895 · 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.
Average true range by day of the week
ZW
| Day | Average range | Sessions |
|---|---|---|
| Monday | 18.3 pts | 772 |
| Tuesday | 17.5 pts | 844 |
| Wednesday | 17.8 pts | 840 |
| Thursday | 17.7 pts | 825 |
| Friday | 17.1 pts | 820 |
n = 4,101 · 2010-06-08 to 2026-09-16 · exchange data
Average daily true range in the instrument's own points. Useful for sizing the stop distance, not for anticipating direction.
Gap fill between calendar days
ZW
| Day | Gap up | Gap down | Sessions |
|---|---|---|---|
| Monday | 75.3% | 74.9% | 733 |
| Tuesday | 88.5% | 92.0% | 710 |
| Wednesday | 87.8% | 91.5% | 720 |
| Thursday | 87.9% | 92.9% | 718 |
| Friday | 90.0% | 91.7% | 707 |
n = 3,588 · 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
ZW
| Day | Closes green | Closes red | Sessions |
|---|---|---|---|
| Monday | 42.3% | 57.1% | 773 |
| Tuesday | 49.1% | 50.6% | 844 |
| Wednesday | 47.1% | 52.1% | 840 |
| Thursday | 44.8% | 53.9% | 825 |
| Friday | 48.2% | 51.0% | 820 |
n = 4,102 · 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?
ZW
| Day | Breaks | Stays inside | Sessions |
|---|---|---|---|
| Monday | 85.3% | 14.7% | 631 |
| Tuesday | 84.3% | 15.7% | 785 |
| Wednesday | 85.2% | 14.8% | 800 |
| Thursday | 87.2% | 12.8% | 784 |
| Friday | 85.5% | 14.5% | 784 |
n = 3,784 · 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
ZW
| Kind of day | Frequency | Days |
|---|---|---|
| Compressed (under 70% of the average range) | 19.8% | 810 |
| Normal (70-130%) | 61.9% | 2,531 |
| Expanded (over 130%) | 18.3% | 747 |
n = 4,088 · 2010-06-25 to 2026-09-16 · exchange data
Compares each session's range with the instrument's own recent average range.
Streaks: does the direction carry into the next day?
ZW
| Streak | Continues | Days |
|---|---|---|
| After 1 day in the same direction | 49.8% | 2,064 |
| After 2 days | 50.7% | 1,026 |
| After 3 days or more | 48.6% | 1,011 |
n = 4,101 · 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.
