OPCG ARB INDEX
The Cardgap One Piece TCG Arb Index is (USD × FX) ÷ JP single price. Ratios above 1.5× signal a buy-in-Japan, sell-overseas opportunity. Bandai prints OPCG in Japan first — overseas releases lag months later, which routinely produces 3×–10× spreads on alt-art SECs and tournament promos.

METHODOLOGY · 計算方法
- USD source: TCGPlayer market price (median of recent listings, single-seller outliers excluded).
- JPY source: Mercari sold-out median + Yahoo Auctions closed median, blended.
- FX rate:
¥157.00 / $, refreshed daily. - Filter: only cards with USD ≥ $5 AND JP ≥ ¥500 are scored to suppress noise on cheap commons.
- Caveats: Arb Index does not include international shipping (~$5–$15) or import duties. Subtract those before pulling the trigger. Bandai grading is not yet a major factor for OPCG (PSA/CGC pop reports are still small).
