Current rule log

Why this product is stamped SELL_WATCH as of Jul 22, 2026.

1. This week · Down 54.2% vs a week ago — sellers have the upper hand right now.
2. This month · Not enough history yet for a monthly read.
3. eBay supply · We started counting live eBay listings recently — the month-over-month supply read unlocks as that history builds.
4. Trend strength · Our core buy pattern: a powerful month-long climb that is still gaining this week. In our historical testing, established trends like this persisted far more often than they reversed.
5. High conviction · A premium product showing our highest-grade momentum pattern. Historically this is the most reliable signal we issue — serious-money products trend hardest in this market.
6. Riding the high · Trading near its all-time high with the broader trend intact. Confirmed in our own testing: in this market, strength at the top is fuel, not a ceiling.
7. Steady premium climb · A premium product grinding steadily higher without weekly drama. Our testing shows this quiet pattern pays at the top end of the market — and fails on cheap cards, so it only counts here.
8. Room to run · A strong trend on a card still trading well below its former peak — old ground left to reclaim. In our testing, momentum with headroom beat momentum at fresh record prices by a wide margin outside the premium bracket.
9. Event runner · A fixed-print event or promo product breaking upward with real momentum. The print run is locked forever, so a new high means demand outgrowing a supply that cannot expand. In our testing this pattern kept climbing more reliably than anything else we track.
10. Overheating check · The price has gone near-vertical compared with its own recent average. Our testing found vertical climbs cool off more often than steady ones — so we hold back the buy stamp on cheaper cards in this state. Fixed-print event promos are the exception: their spikes historically stuck.
11. About dips · Counter-intuitive but tested: in this market, dips during uptrends usually keep dipping. A discount alone never makes us say buy.
12. Rebound setup · The bargain-hunter pattern: a hard fall that has just turned upward, with price swings calming, on a set past its launch chaos. Speculative by nature — the winners historically paid well, but only about half the calls win.
13. Why this stamp · Either falling hard this week, or a big run just rolled over. Historically, cards in this state kept falling more often than not. If selling was on your mind, this is the decide-now flag.
14. New set caution · Sets under about three months old swing wildly while boxes get cracked. Extra scepticism on brand-new sets.
