Set Demand

About set demand

What does set demand measure?

A set-level inventory-flow signal: how quickly buyers absorb visible supply compared with implied new listings for that set’s tracked sealed products on TCGPlayer. Most sets have one tracked booster display, so this is a set-level signal rather than a sum across every SKU. Commander covers deck displays and cases; individual decks live on Market Pulse.

How is demand measured?

Over the trailing 4 weeks, we combine supply-flow observations from a set’s tracked products. The ratio compares average daily units sold with a trimmed average of implied new supply. Above 1.3× is Heating; below 0.7× is Cooling; the middle is Watch. A set needs at least 14 distinct days of history and 10 units sold in the window for a confident call — the product-level 7-day / 5-unit gate scaled to four weeks. This deliberately moves more slowly than Market Pulse.

How often does this update?

Supply snapshots are captured daily and sales are pulled from TCGPlayer; the leaderboard rebuilds with each daily deploy. The trend covers the trailing 8 weeks: bar height is weekly units scaled to each set’s own peak week (hover for absolute units), while bar color shows that week’s demand ratio. Weeks under 5 units are muted because a one-unit week can hit the 5× cap.

Where does the data come from?

All sales and supply numbers on this page come from TCGPlayer. This page is about units moving, not price — prices elsewhere on the site use a 14-day quantity-weighted trimmed mean.
