📊 Asset Selection Methodology


1. High-Liquidity Threshold

Assets must average 30+ verified sales per month. We prioritize a "Tight Spread" where the gap between Floor and Market is < 10%.

2. Condition Filtering (NM/LP Only)

To prevent data distortion, we exclude "Damaged" or "Heavily Played" listings. Pricing reflects Near Mint (NM) or Lightly Played (LP) collectible standards.

3. High-Interest Index

We track search velocity and "Watch-List" activity. Selected cards maintain 20+ active watchers per listing on major marketplaces.

4. Verified Data Policy

Historical charts strictly display first-party recorded data. We do not use simulated trends; chart history populates as our system logs daily market activity.

Data Methodology & Transparency Report

1. Data Sourcing & Frequency

Our asset valuation engine integrates with the PokemonTCG.io Global API, which aggregates transaction data from the TCGPlayer Market. Data is synchronized with our proprietary SQL database once every 24 hours (00:00 UTC) to ensure “Daily Close” accuracy.

2. The Valuation Formula

To provide the most stable “Asset Value,” we prioritize the Market Price over the “Listed Price.” While listing prices represent seller sentiment, our Market Price represents the actual realized value of the last 10-20 verified sales.

V = Σ(Verified Sales) / n (within 24h window)
3. Accuracy & Precision

Data precision is maintained to two decimal places. Please note that “Near Mint” (NM) holofoil values are used as the primary benchmark. Fluctuations under 1% are considered market noise and are reflected in the Trend History graph below each asset card.


🎯 Target Audience: Who is this for?

This tool is primarily designed for three types of users:

  • Active Collectors: Individuals looking to “buy the dip” on high-value grails or modern alternate arts. They need to know if a card is currently priced near its historical floor or if it is over-inflated.
  • Alternative Asset Investors: Users who view high-end Pokémon cards as financial assets (similar to stocks or crypto). They rely on the Price Change Percentage and Market Trend Lines to manage their portfolios.
  • Hobbyist Sellers: People looking to list their cards who need an instant “pulse check” on the current market floor and 24-hour volatility to price their items competitively.

🛠️ The Purpose: What is this data useful for?

The dashboard provides three specific utilities:

  1. Arbitrage Identification: By seeing the “Floor” price alongside the “Market” price, users can quickly spot opportunities where a card is undervalued on one platform compared to the aggregate market.
  2. Volatility Tracking: The 24-hour change badge tells a user if the market is “hot” or “cold” for a specific card, helping them decide whether to buy now or wait for a correction.
  3. Historical Context: The line charts solve the “Goldfish Memory” problem of the hobby, showing whether today’s price is a momentary spike or a sustained growth trend.

🚀 The Core Problem: What are we solving?

The dashboard solves the Problem of Information Asymmetry.

In the Pokémon market, prices change by the hour across multiple websites. Without a dashboard like this, a user has to open five different tabs, search for a card name, filter for condition (Holo/Near Mint), and manually remember what the price was yesterday.

The Solution:

  • Aggregation: We bring eBay and TCGPlayer into a single view.
  • Visualization: We turn a list of boring numbers into a visual trend.
  • Focus: We filter out the “noise” by tracking only high-liquidity, high-interest assets, saving the user from “analysis paralysis.”

Essentially, our idea is to enable the hobbyist to stop guessing on card market pricing and instead visualize and take decisions based on data.
