ME: 30th Celebration’s regular retail Elite Trainer Box is priced at $140, sitting at 4% of its tracked 90-day range. eBay active listings have moved +550.0% over the tracked supply window (artifact-filtered, median-to-median). This set released 26 days ago — launch allocation is still selling through, so contracting supply is expected retail behavior, not a squeeze. Buy/watch signals unlock once the set matures. It trades at 2.8× its $49.99 retail price.
Context & evidence · data confidence B: moderate price history (48 reads / 102 days) · 23 supply reads · volatility measured · volatility tier Jumpy. ETB signals run the full sealed stack (upgraded 2026-07-10): supply+price core, NEW maturity gate, market-relative strength, and retail-price anchor. The set÷box ratio and Rip Score stay excluded — they don’t translate to a 9-pack product. Every run is logged to the ETB Signal Log so the backtest can grade these dials.
