Where these prices come from

Yu-Gi-Oh prices on TCGIndex are TCGplayer market prices (the US market), in US dollars. Another currency is a conversion from USD at the day's rate, not a European market price. We do not use Cardmarket or Cardtrader prices for Yu-Gi-Oh.

Before the price moves

We find the Yu-Gi-Oh cards about to rise.

Every night the model scores every Yu-Gi-Oh! card on the market. Every morning at 07:30 UTC it publishes the one most likely to gain 10% within 30 days, with its entry price and the reasons, then scores it in public.
