How to read this market
Numbers alone do not make a decision. The index tells you the direction of the whole Union Arena market, the movers show where attention is flowing, and the most-valuable list shows where the deep, durable demand sits. Read together they separate a real trend from a single noisy sale. And because TCGIndex logs every pick it flags with an entry price and date, you can check the track record rather than take any of it on faith.
