One Piece Card Game

How to read the market

What does the number mean?

It is an index. One Near Mint copy of every card at fair value, compared week to week on the same cards. It starts at 100, so 107 means those cards are worth 7% more than when the line began. The most valuable cards move it most.

Where do the prices come from?

From real sales only. A listing never counts, and neither does a marketplace's own price.

How often does it change?

The lines are rebuilt once a day and each point is one week. The newest sales show as they come in.

Can I buy an index?

No. An index is a measure, like a stock index: it shows how a game's cards are moving. Tradewind doesn't sell shares of cards or hold money for anyone.
