TCGscreener is a stock-style screener for the Pokรฉmon Trading Card Game. Every card carries a modeled dollar marketcap (estimated print run ร current price across PSA grades) so 40,000+ cards can be ranked by valuation the way Finviz ranks stocks: by momentum, volume, scarcity, and arbitrage between markets.
## Features - Screener โ Filter by 30+ signals: marketcap, PSA 10/9/8 pop, RSI(14), days-to-cover, % off 52-week high, EU/US arbitrage gap - Top movers โ Daily gainers/losers per set across 1d/7d/30d windows with chart heatmaps - Sealed EV โ Find booster boxes and ETBs with the best rip-to-singles expected value - Weekly Pulse โ Auto-generated Pokรฉmon TCG market commentary published every Sunday - Confidence dots โ โโโ/โโโ/โโโ on every modeled estimate separates solid signal from noise
## What makes it different Other TCG focused sites tend to be mostly price-lookup tools. They tell you "what's this card worth?" TCGscreener answers "what should I buy?" by layering discovery, filtering, and analytics on top of pricing. Marketcap methodology, print-run priors, and grade-share assumptions are versioned in public so the modeled numbers are auditable.

TCGscreener's answer
TCGscreener applies stock-market analytical concepts โ marketcap, RSI, momentum, % off 52-week high, days-to-cover to the TCG market, which no other card-tracking site does. Every card carries a modeled dollar marketcap (estimated print run ร current price across PSA grades), so 40,000+ cards can be ranked by valuation the way a Finviz user ranks stocks. This creates new ways to find undervalued gems or even just cool new cards to add to your collection.
TCGscreener's answer
Other sites are primarily price-lookup tools. They answer "what's this one card worth?" TCGscreener answers "what should I buy?", and "what should I hold".
All free, no signup necessary. Daily price refresh to keep the data current.
TCGscreener's answer
Engaged Pokรฉmon TCG collectors and small-scale resellers who treat their collection like an investment portfolio rather than purely personal sentiment.
The core user: someone who already knows what individual cards are worth and wants tools to find undervalued cards, compare sealed-product ROI, and track market momentum across the catalog.
Sealed-product investors (booster-box flippers tracking rip-to-singles ratios) are a meaningful secondary audience.
TCGscreener's answer
I've been a collector of MTG and pokemon for close to 30 years. I also went to school for finance and have been "collecting" stocks since I was 10 years old.
The Pokรฉmon TCG market alone has millions of active collectors and billions in annual secondary-market sales, but the analytical tooling lags decades behind what stock traders take for granted. Existing card-price sites tell you what a card is worth right now; none tell you which cards are undervalued, trending, or have unusual liquidity.
TCGscreener started as a personal tool to scratch that itch. Finviz-style screening for a hobby that already behaves like a financial market, and grew into something other collectors and resellers found useful. Built solo as a side project and running lean.
TCGscreener's answer
Next.js with TypeScript and React; PostgreSQL on Railway with Prisma ORM; Tailwind CSS 3 for styling; lightweight-charts for time-series visualizations.
TCGscreener's answer
