← Back to blogSale velocity (35%) — How many transactions happened in the past 7 days relative to the shoe's trailing 90-day average. A shoe selling 3× its baseline scores high here. Bid depth (25%) — The number of active bids and how close the highest bid is to the last sale price. Deep bid books at tight spreads signal strong buyer conviction. Price trajectory (25%) — Whether the last-sale price is trending up, flat, or down over 14 days. We use a linear regression slope normalized to the shoe's own price range. Search and media mentions (15%) — Aggregated from sneaker news sources. A shoe getting covered by SneakerNews, Hypebeast, or Kicks on Fire in the past week gets a bump. High demand + high premium + low volatility = stable grail High demand + low premium = potential entry point High demand + high volatility = hype play, watch carefully
