Demand

Units actually sold over the last 30 days across tracked $50+ singles — real transactions, not listings or views.

One big month is noise, so persistence counts how many months a card has held a top position — the harder thing to fake.

Core

— A top-10 seller in most months. The most durable demand on the board.

Mainstay

— A top-20 seller in most months. Durable, repeat demand.

Recurring

— A top-50 seller in most months, even when it does not reach the top 20.

Emerging

— Has broken into the top 50 at least once. Building or intermittent.

Minor

— On the board, but rarely a strong monthly seller. Light demand.

Where the card sits now against its rank about three months ago. A record of what already moved, not a forecast.

Surging

— Climbed 5 or more rank places versus three months ago, or came back onto the list.

Rising

— Climbed 2 to 4 rank places versus three months ago.

Steady

— Holding roughly the same rank as three months ago.

Cooling

— Slipped 2 to 4 rank places versus three months ago.

Falling

— Slipped 5 or more rank places versus three months ago.

Debut

— One month of history so far, so there is nothing to compare it against yet.

Stale

— Not on the list in the latest month.

A heavily-traded card can still be expensive against its fundamentals. Read the vs-fair column alongside the volume.
