Does the open close back to yesterday?

Built from a Nasdaq 100 / S&P 500 / Dow 30 index tape, not from exchange futures ticks. Bar to bar return correlation against real MNQ is 0.988 over a 5,238 bar overlap, and 93 to 94 percent of swing pivots land on the same bar. The one minute pull is cross checked against a lossless local tick set over 2026-06-10 to 2026-08-25 and must correlate above 0.98 to ship. Levels are relative, so the rates hold; absolute prices carry a basis of roughly 160 points that drifts.

Sample runs 2021-01-05 to 2026-09-04, 1,379 sessions. Skipped: 45 half days, 39 data holes, 16 sessions the report did not apply to.
