New listings per day
Building
How much new stock hits the UK market each day The scanner records every new UK listing it sees — around 13,600 a day. This charts how many appear for this card once the daily rollup has readings for it.
A direct count of listings we saw appear — not an estimate of every listing on eBay.
Confirmed sales per day
Building
How often this card actually sells We record roughly 4,600 UK auction outcomes a day across the catalogue. This charts how many close with a winning bid, day by day, from the first confirmed sale for this card.
Only auctions that finished with a bid count. A listing vanishing is not proof of a sale, so it is not counted as one.

Live UK listings for this card The scanner records every new UK listing it sees — around 13,600 a day. This fills as soon as one appears for this card, showing asking prices cheapest first.
Where these numbers come from
Three independent readings, shown side by side rather than blended into one figure:
HoloHawkOur own market price, from live UK listings
PriceChartingPublished reference price, USD converted to GBP
PulseTCGPublished reference price, natively GBP
A reading is stored only when a price actually changes, so flat
stretches mean the price held — not that data is missing. Where a source has no history for an item its
line is absent rather than flat. Confirmed sales are UK auctions that closed with a winning bid, observed
within three minutes of close, so each is a lower bound. Live listings are asking prices, not sales.
Supply and sales counts are direct observations — listings we saw appear and auctions we saw close with a
bid. We do not infer that a listing sold because it disappeared, so nothing here depends on that guess.
