New /anomalies/compare page runs every saved strategy preset over the same
window and ranks them by ROI — bets, W–L, hit-rate, net, and max drawdown side
by side, with the best ROI flagged. Auto-runs on load with an optional date-range refine.
- CompareStrategiesUseCase fans RunBacktestUseCase over saved presets (re-loads the
anomaly set per preset — fine for the handful a user keeps; stays bug-for-bug
identical to a single backtest run).
- StrategyComparisonService.BuildVm (pure) computes per-row hit-rate + a single
best-by-ROI flag; nav entry + en/ru resx.
- 6 tests: use-case fan-out + BuildVm best/tie/no-bets/hit-rate.
