Five daily series recording what marketplaces publish today and overwrite tomorrow - card prices, used cars, hiring, resale and retail stock.
None of these is for sale yet. They are being accumulated, because the one thing that cannot be bought later is the past.
Trading card price history, daily, 21 games
Every priced product on Cardmarket, captured daily since September 2026 - the daily series the marketplace itself does not publish.

Used car asking prices and listing lifecycles
Daily asking prices with mileage, year, fuel and transmission across Dutch, Belgian and Austrian marketplaces.

Hiring history from company career sites
Open roles per company per day, read from employers' own career pages rather than job boards.

Resale sold comps, recovered by observation
What second-hand fashion actually sells for, inferred from listings that disappear - on a marketplace that publishes no sold history.
written, not yet scheduled · from 2026-09-19 · Eight tracked niches across three country sites
Retail price and stock availability over time
Daily prices and in-stock state across consumer electronics categories on the largest Dutch-language retailer.
written, not yet scheduled · from 2026-09-19 · Six categories, several hundred products a day
A site that shows only its current state is a site whose history nobody owns. Asking prices are replaced, sold listings are deleted, job postings vanish when filled, and a price guide is overwritten every night. Whoever started saving timestamped copies holds something that cannot be reconstructed afterwards at any price.
These pages describe the series; they do not publish the rows. Aggregated figures drawn from them appear on the free data pages, and the tools that produce them are in the catalogue. Page generated 2026-09-19 23:39 UTC.
