Corn ZC
Historical statistics for Corn over 19,585 observations, from 2010-06-07 to 2026-10-23. Every table shows its sample size (n) next to the percentage.
What sets this instrument apart
- An upside gap between one day's close and the next day's open fills in ZC between 71.4% of the time on a Monday (n = 266) and 92.3% on a Wednesday (n = 247). The gap between Wednesday and Monday exceeds noise (two-proportion test, Holm-corrected over the 10 pairs of days), but in a contract trading nearly 24 hours that gap is small, which is why it closes so often: it is not a tradable edge.
