About these alerts
Alerts are computed daily from price snapshots across Mercari (sold listings), Yahoo Auctions (closed bids), Card Rush (buyback prices), and TCGPlayer. Each alert ranks by composite score combining surge magnitude, volume, and recent volatility. Cards with abnormal data (>±500% 30-day or >±200% 7-day) are filtered out as data noise.
