Data index
Auction market calendar index
A live public snapshot of the HammerAlert auction calendar: how many upcoming sales are being tracked, where the next-week pressure sits, and which fields and houses currently carry the calendar.
Data snapshot: 3 September 2026 UTC. Written and maintained by Laurens Lokker.
What the index measures
The index counts future and currently open auctions in HammerAlert's normalised calendar. It is not a price index and it does not measure bidding volume. Its purpose is practical: showing where auction-calendar activity is concentrated so collectors can decide which fields, houses and regions deserve attention.
