Places, containers, dividers
Every row has a home. Move a card between binders or behind a divider and the collection view follows that physical path.
COLLECTION
A collection tracker that knows where the cards live.
Tradepost models the physical collection first: boxes, binders, shelves, dividers, sealed product, and the places those containers sit. Pricing and trends attach to that real inventory instead of a loose spreadsheet.
Accounts open in batches during the public playtest.
Per-printing value
Nightly market syncs keep priced printings current, and manual overrides cover the cards the catalog cannot price yet.
Honest trends
Snapshots, movers, and rollups are based on stored collection state. No invented totals, no extrapolated history.
