2026-04-11: Continuing local quant research in cyb50-quant.
User asked for concrete backtest results, not just brainstorming.
Scope is intentionally narrow: backtrader-lab/ experiments for 1) multi-index dual-momentum rotation and 2) Chinext50 single-index trend-following with cash/flat regime control.
Deliverables requested: minimal code/config changes, actual backtest runs, concise markdown results file, reproducible commands, and a completion notification via openclaw system event.
