Collection value

The value screen, what the total includes, and how the nightly history is built.

Collection Value charts what you own, day by day.

What the total includes

Binders plus tracked decks. A proxy is left out, and so is a card with Tracked turned off. Lists never count.

The chart, over 7D, 30D, 90D, 6M, YTD or 1Y, with Total, Normal, Foil and Etched chips to split it by finish.
Four tiles: Period high, Period low, Change and All-time high.
Value by source — how the value splits between your binders and your tracked decks. The word source means something different here than it does everywhere else in this manual, where it means a market.
Most valuable cards, with a Top 100 link that appears once more than 100 of your cards are priced. It opens the full ranked list.

The chart is built from nightly snapshots taken at 23:30 UTC, after the day's prices land, so each point is that day's close.

Snapshots are per price source. Each source keeps its own history of your collection, and the chart draws the one for your active source. Switching sources switches the whole curve; it does not redraw the old one in new money.
Each snapshot is valued as of its date: your inventory that day, at that day's prices, one price day for the whole snapshot. The curve is a series of real observations, not today's prices projected backwards.
Today's changes appear after tonight's snapshot. Cards you add or remove during the day are captured, valued at that date, when the 23:30 UTC run happens.

Every binder, list and Owned Cards has its own Data screen. See Binders.
