Tool Nut · Sep 03 2026–Sep 23 2026

The plotted record breaks across 1 missing observation run. The vertical price scale visibly starts at $323. The 90-day rule selects its reference. This record contributes a 21-day observed span; all 20 price-days and 1 missing run are shown.

Why this form

The 90-day rule selects its reference. This record contributes a 21-day observed span; all 20 price-days and 1 missing run are shown. Daily tracking had not yet begun in the earlier part of the rule frame; that time is not a coverage gap.

Every line uses reduced price-days for one exact retailer offer. Both series share the coverage mask; intraday and Class B facts remain detached marks. The receipt ledger below is the complete text alternative.
