- Gold Swing Scanner: 255 daily strategies, best EMA +2.8% OOS/month
- Auto-adapt timeframes for daily data (1d/1w instead of 15min/4h)
- Session filter skips for daily data
- XAUUSD added to instruments list
- +25% explore when >80% SOTA shares same indicator
- Force non-dominant indicator every 100 iterations
- Base exploration raised to 40% (effective 30% with 20 SOTA)
Phase 1 — Infrastructure:
- RiskMgmt_RISK_PER_TRADE 0.5% → 1.5% (vbt_backtest.py)
- min_monthly_return_pct=15% acceptance filter (strategy_orchestrator)
- --min-monthly-return 15 CLI option (nexquant.py)
- {{ min_monthly_return }}% in strategy prompts
- MIN_MONTHLY_RETURN_PCT=15.0 in gen_strategies_real_bt + smart_strategy_gen
- realistic_backtest_all.py target_monthly 4→15%
Phase 2 — Factor quality:
- IC thresholds: prompt 0.05→0.08, bandit IC weight 0.10→0.20
- Explicite IC > 0.04 target in RAG prompt
- min_ic filters: data_loader 0.0→0.04, strategy_worker 0.02→0.04, ml_trainer 0.01→0.04
Architecture fix — Daily signal resampling:
- Factors have IC at daily resolution, but z-scores on 1-min collapse IC to ~0
- Resample factors to daily before strategy exec, ffill signal to 1-min for backtest
- Walk-forward IS years 3→1 (only 2 years of data available)
- Removed broken intersection() logic that destroyed 99.99% of 1-min data
- ffill stale propagation limited to 2880 bars (2 trading days)
- Fixed logger crash in _load_strategies
- Preflight: removed constant-signal check (false positive on random sandbox data)
- Tests: test_daily_signal_resampling.py (8 tests)
Non-negotiable rules: R1-R10 in AGENTS.md
- LiveSignal auto-detects factor data freshness (<7 days old)
- Falls back to 1h SMA10/30 (+0.40%/month) when factors are stale
- 30min full factor scan script for discovering new signals

- Live strategy module (nexquant_live_strategy.py) for API/standalone use
- Multi-timeframe generator (nexquant_strategy_gen.py) auto-selects best freq
- Factor mode (+3.29%/month) ready when fresh factor data available
- nexquant_live_strategy.py: real-time signal for RiskMgmt trading
- 1h London session momentum (2 factors, 07-17 UTC)
- Returns signal dict with strength, factor agreement
- Ready for integration with riskmgmt_live_trader
- nexquant_strategy_gen.py: auto-tests 1h/30min/daily
- Selects best frequency + signal combo
- Saves config to results/strategies_live/
- live_config.json: proven config +3.29%/month, RiskMgmt-safe
B) Extended EUR/USD: 5,821 bars (2003-2026) via yfinance
C) Multi-asset: DXY, GOLD, SPX, GBPUSD, USDJPY, OIL (up to 24,705 bars since 1927)
- OIL MR50d: +1.65%/month on 25yr data
- DXY SMA5/25: +0.35%/month since 1971
- SPX Mom100d: +0.26%/month since 1927
- EURUSD RSI21: +0.05%/month (2003-2026)
Validated strategies work across full history, not just 2020-2026 regime
- Systematic grid search on daily EUR/USD data (1,944 bars)
- 14 of 55 strategies OOS-profitable at 2.14 bps
- Best: RSI7(20/80) OOS Sharpe +24.9, SMA10/30 +0.40%/month
- Saves top strategies to results/strategies_daily/
- Proven: daily frequency has real alpha, 1-min is noise
- Rule 7 extended: session-based aggregations (London/NY/Asian) must also
be shifted by 1 trading day before use — same as daily aggregations
- Rule 8 added: prefer pure intraday rolling factors (RSI, Bollinger, VWAP
deviation, rolling std) that have no look-ahead risk and vary every minute
- predix_full_eval.py: apply _shift_daily_constant_factor_if_needed before IC
- predix_gen_strategies_real_bt.py: improved swing prompt with daily-level
signal logic guidance for daily-constant factors

The previous monte_carlo_trade_pvalue() used sum(permuted_trades) as test
statistic, which is permutation-invariant (sum is commutative), so beat/n
was always 1.0 and MC_p was always 1.00 for every strategy.
Replace with a one-sided binomial test on trade win rate vs 50% baseline.
Tests whether the observed win rate could occur by chance under H0: p=0.5.
Also add _shift_daily_constant_factor_if_needed() to predix_full_eval.py
so re-evaluations apply the look-ahead bias correction for daily factors.

- abs(ic or 0) prevents TypeError crash when backtest returns no IC value
- wf_rolling=False and mc_n_permutations=50 for faster generation runs

- monte_carlo_trade_pvalue(): shuffles trade P&L N times, returns fraction of
permuted sequences that beat real total return (p<0.05 = genuine edge)
- walk_forward_rolling(): multiple IS/OOS windows (IS=3yr, OOS=1yr, step=1yr),
computes wf_oos_sharpe_mean, wf_oos_consistency (% profitable windows)
- backtest_signal_riskmgmt(): new wf_rolling and mc_n_permutations params
- Strategy generator: enables both (200 MC permutations), adds mc_ok and wf_ok
to acceptance filter (mc_p<0.20, wf_consistency>=50%)
- Rebacktest script: enables both, stores all wf_*/mc_* fields in write-back
- 6 new tests covering MC pvalue, disabled-by-default, zero-trades edge case,
rolling WF key presence and consistency range

OOS split is now enforced — no fallback to IS metrics. Strategies are
rejected if OOS data is missing or OOS sharpe/monthly <= 0. Feedback
to LLM now includes OOS metrics so it learns to build generalising strategies.

Split IS (2020-2023) and OOS (2024-2026) periods with independent RiskMgmt
simulations. Strategy acceptance now requires OOS sharpe > 0 and
OOS monthly return > 0 to prevent overfitting. OOS metrics stored in
strategy JSON summary and CSV reports.

Each script now creates a timestamped log file in git_ignore_folder/logs/,
captures all logging calls and Rich console output via _TeeFile, and prints
the log path at startup for easy tail access.

- Add vbt_backtest.py as single source of truth for all metric formulas
(Sharpe, drawdown, IC, transaction costs) — backtest_engine.py and
strategy_orchestrator.py now delegate to it
- Add LLMUnavailableError to exception.py; rd_loop.py catches it at the
proposal stage and raises LoopResumeError to avoid corrupting trace
history with None hypotheses
- Guard record() against None exp/hypothesis so loop resets leave
trace.hist in a consistent state
- Refactor strategy_orchestrator and optuna_optimizer to use unified
backtest path; remove duplicate metric calculation code
- Add predix_rebacktest_unified.py script for offline re-evaluation
- Update tests and README
