results: raw_next fix verdict — training Sharpe +0.19 avg, peak 1.02, WinRate 25%
Root cause: experience collector used raw_next (future price) for P&L,
creating 1-bar action-reward misalignment. 30+ H100 runs couldn't
overcome this. Fix: use raw_close only + trade-level P&L.
Result: WinRate 45%→25% (selective), Sharpe 0→+0.19 avg,
peak 1.02 (3 times), PF 1.09, 67% positive epochs.
First genuine asymmetric trading strategy in the project.
