New listings per day

From tomorrow
How much new stock hits the UK market each day Listing capture began today and the first daily rollup runs tonight. From tomorrow this charts how many new listings appear for this card, so you can see supply building or drying up.

A direct count of listings we saw appear — not an estimate of every listing on eBay.

Confirmed sales per day

From tomorrow
How often this card actually sells We record roughly 4,600 UK auction outcomes a day across the catalogue. From tomorrow this charts how many close with a winning bid, day by day.

Only auctions that finished with a bid count. A listing vanishing is not proof of a sale, so it is not counted as one.

Recent confirmed sales

Recording live
No confirmed sales for this card yet We log every UK auction that closes with a winning bid — around 4,600 a day across the catalogue. The first result for this card appears here as soon as one sells.

Building
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:

HoloHawk Est. Market Our own estimate, from live UK listings
PriceCharting Published reference price, USD converted to GBP
PulseTCG Published 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.
