SealedPulse

The European MTG sealed market, measured. An equal-weight index of English collector booster boxes across the European market — our own curated price series, collected 3×/week with scam listings filtered out — plus real price floors, US-vs-EU gaps, and a bait-watch. 
Run by Rasmus, a data engineer in Copenhagen, with his own money in the market and every number logged publicly at sealedpulse.com. We're also testing the "US leads Europe" theory with a pre-registered study — verdict September 15, published either way. Not affiliated with any marketplace. Educational content, not financial advice.
