In-sample winner → out-of-sample reality
For each horizon we take the config a naive optimiser would have shipped (best in-sample $) and show what it did on the held-out window. Green in, red out — that’s overfitting, shown on purpose.

How it’s modelled: WITH hard stop (operator spec). A stop caps the normal loss, but a gap/crash beyond the ~0.9/leverage liquidation buffer at 2-3× still wipes the margin — modelled. Realistic frictions: 5 bps/side + 2 bps/side slippage + perp funding over the hold. Dip-buy entry on the bar low, no look-ahead. Configs SELECTED on in-sample only; OOS = held-out last 30%, the honest judge. 5m history ~2 weeks (30% targets rarely hit intraday). Demo/paper experiments — live stays BLOCKED behind the proof gate.
