PRICE HISTORY / HKT
Reference-price trend
Tap or drag across the chart to inspect each point. You can also use the left and right arrow keys.
Choose a product, packaging option and D, M or Year to update the chart.
METHOD / SCOPE
A transparent index, built from Cardstop data.
The dashboard is a record of Cardstop group-buy reference prices for research and transparency—not an investment product.
Important: Reference prices are not completed sales, guaranteed availability, card valuations or investment advice.
Daily capture
Google Apps Script saves one HKT observation after your Sheet update.
Stable identity
product_id connects observations when display names improve.
Index baseline
Category indices start at 100 and use median normalized movement.
No invented history
Missing days and unavailable prices are never estimated.
