Every number on Doirado is computed from listings we observe directly on European marketplaces — Reverb, OLX, Facebook Marketplace, eBay, and more being added. We record what was asked, what happened to the listing, and when. Nothing is copied from other price guides, and nothing is estimated by a model.
Sold prices
A product's median is computed from recorded sales, converted to EUR at the daily exchange rate for the day in question. Before the median is taken, we band out prices more than ten times above or below the product's own long-run median: bundles, spares-or-repair listings, typos, and jokes are real listings but they are not the price of the thing.
We always prefer the tightest window that has enough data behind it — the last 90 days when the product trades often, falling back to six months, then two years, and the page tells you which window you are looking at. A median built on fewer than eight banded sales is not shown at all. A number without enough data behind it is worse than no number.
One honest caveat: most recorded "sold" prices on marketplaces are final asking prices, not settled amounts. Where offers are common, real transaction prices sit somewhat below what we can observe. We weight sources by how close their sold flag is to a true transaction, and winning auction bids — which we watch to the end ourselves — count for more than a seller's own "sold" mark.
Time to sell
"Sells in 14 days" is only ever computed from listings we watched from listing to sale — first seen while still for sale, confirmed gone later. We never infer speed from when our crawler happened to find something. This is a high bar, and it means some products honestly say "not enough watched sales yet" while the data accumulates. We would rather say that than invent a number.
Sell-through
The share of watched listings that ended in a sale rather than expiring unsold, over the last 180 days. It answers a different question than price: not "what is it worth" but "will it actually move".
Live listings and deal scores
A listing's deal score compares its asking price to the product's sold median: a listing 20% under the median of 34 recorded sales is a 20% deal, and the page shows you the median and the 34 so you can check the claim. We show the platform, price, condition, country and a link to the source — never the seller, and never someone else's photos or text.
What we are not
Doirado is not a marketplace and sells nothing. We link to listings where they live. Prices shown are market observations, not offers or appraisals, and the sample size next to each number is the honest limit of what we know.
