About
Sealed market research, cleaned up
Made by Jordan with Codex.
A cleaner read on Pokemon sealed markets.KJ Trader centers on sealed products first: what is active, what is moving, which sets matter, and where real sale history supports the signal.
This is an early Pokemon sample segment, not the final boundary of the product. The larger goal is to expand into broader collectible markets with cleaner cross-market reads from sources such as eBay, Fanatics Collect, Goldin, Heritage, and other auction or marketplace venues as coverage improves.
How To Use It
Start with Overview. Check the overall market pulse: tracked sealed products, active sets, recorded sales, and the highest-activity areas.
Open Sets next. Pick a set to compare its sealed products and supporting card activity side by side.
Use Indices for movement. Market baskets show whether groups of products are trending up, down, or sideways from a normalized base.
Use Lookup for catalog research. Search sealed products or cards by name, set code, SKU, or TCGplayer product ID.
Glossary
- Sealed product
- Unopened Pokemon products such as booster boxes, ETBs, booster bundles, packs, tins, cases, and collection boxes.
- Set
- A release such as Prismatic Evolutions or Journey Together. Sets group related cards and sealed products.
- Generation
- The broader Pokemon release period a set belongs to. The database may still call this an era internally.
- Recorded sales
- Sales observations stored in the database. More sales usually means a stronger read on current demand.
- Market basket
- A group of products tracked together, similar to an index. It helps show how a category is moving overall.
- Index
- A basket tracked from a normalized starting value of 100, so movement is easier to compare across products or cards.
- Index performance
- The trend line for an index over time. Up means the basket moved higher from its starting value; down means it weakened.
- 30 day
- A recent activity window covering roughly the last month of recorded observations.
- Last sale
- The most recent recorded sale price available for the item.
- Price history
- Recent observed prices plotted over time. It is a read on available observations, not a guaranteed full-market history.
- Source mix
- How recent observations split between TCGplayer and eBay.
- Priced days
- Days in the chart window with enough observations to calculate an index value.
- Top volume
- Items ranked by recent recorded sales volume.
- Basket contents
- The visible cards, products, sets, or generations currently included in the selected basket preview.
- Confidence
- A rough read on how much recent data supports a price or activity signal.
Data Notes
TCGplayer is the structured catalog and sales layer. eBay comps are treated as beta coverage while matching and cleanup continue. Market data is informational, not financial advice.
The current public success marker is simple: make useful market data visible enough that collectors can answer real questions faster than they could from scattered listings alone.
Built with Codex, FastAPI, PostgreSQL, Caddy, Vercel, and a lightweight HTML/CSS/JavaScript frontend.
