WondersTracker
Market prices for the Wonders of the First trading card game, tracked across eBay, Blokpax and OpenSea, with portfolio tracking and alerts.
WondersTracker tracks every sale of Wonders of the First cards across marketplaces, computes a fair market price for each card, and gives collectors portfolio tracking and Discord alerts for deals.
The pricing runs on my own autoregressive pricing models, backed by notebooks on order books and floor prices. Nearly 1,000 commits over two months, plus a subscription tier.
