Added explicit policy to QWEN.md:
- List of forbidden closed-source files (git_ignore_folder/, local/, .env)
- Explanation of why (alpha protection, security, repo size)
- Clear separation: open-source framework vs closed-source alpha
- Detailed file-by-file breakdown of what is public vs private
- Backup instructions for private assets (separate repo)
- Verification steps before commit
This protects our competitive edge (models, prompts, trading scripts)
while keeping the open-source framework fully functional for users.
Added explicit policy to QWEN.md:
- List of forbidden file types (*.json, strategy outputs, backtest results)
- Explanation of why (repository is for CODE only)
- Where strategies actually belong (results/ - gitignored)
- Prevention steps (.gitignore, git status checks)
- Lesson learned from April 9, 2026 incident (204+ JSON files)
This prevents future accidental commits of generated data.
- Deleted 204+ JSON strategy files from Git history using BFG Repo-Cleaner
- Added *.json to .gitignore (excluding package*.json)
- Removed all loose JSON files from root directory
- Git GC completed: 13,221 objects cleaned
These files were accidentally committed strategy outputs that should
never have been in the repository. The actual strategy files belong in:
- results/strategies_new/ (managed by .gitignore)
- strategies/ (managed by .gitignore)
Step 1 - Evaluierung bekannter Strategien:
- Added 'close' to exec context for existing strategies
- Strategies can now use close.index for signal creation
- MomentumDivergenceZScore evaluates correctly: Sharpe=3.59, DD=-0.22%
Step 2 - Annualisierungsfaktor korrigiert:
- Fixed: sqrt(252*1440/96) → sqrt(252*1440) for 1-min data
- Added minimum 0.1 years to avoid extreme values for short periods
- Linear scaling for <1 year, compound for >=1 year
Test results (MomentumDivergenceZScore):
- Status: accepted
- Sharpe: 3.59 (realistic)
- Max DD: -0.22%
- Win Rate: 49.46%
- Ann Return: 543.75% (linear scaled for 259 min period)

Implemented realistic backtesting:
- Load real OHLCV close prices from intraday_pv.h5
- Calculate real price returns (pct_change)
- Apply signal positions to real returns with proper alignment
- Include spread costs (1.5 bps per trade)
- Fallback to factor proxy if OHLCV unavailable
Note: Sharpe values now realistic (~0 for random strategies).
Strategies need LLM to select predictive factors for positive Sharpe.

Problem:
- run_real_backtest generated script with 'FORWARD_BARS = {FORWARD_BARS}'
- FORWARD_BARS was defined in if/else block but not visible in f-string
- Caused 'NameError: name FORWARD_BARS is not defined' in subprocess
Fix:
- FORWARD_BARS now correctly resolved in f-string at script generation time
- Verified with unit test: FORWARD_BARS=96 correctly embedded in generated code

9/9 strategies now have PDF reports (589KB each, 7 pages)
Problem:
- Backtest used 1-bar returns (pct_change().shift(-1))
- Factor IC was evaluated on 96-bar horizon
- Mismatch caused IC ≈ 0 for all LLM strategies
- Simple sign signal had IC=0.0005, Sharpe=0.08
Fix:
- Changed to 96-bar forward returns: pct_change(96).shift(-96)
- This matches the factor IC evaluation horizon
- Simple sign signal now: IC=0.1826, Sharpe=11.46, WinRate=56%
Also:
- Removed incorrect signal.shift(1) lag (signal already uses future data from factors)
- Fixed signal alignment to use 96-bar forward return index
Problem:
- Log output contained raw ANSI escape codes like [96m[0m
- This happened because LogColors always output color codes even when not in terminal
- Made logs unreadable when redirected to files or run in background
Fix:
- Added _should_use_colors() check in LogColors class
- Colors now disabled when NO_COLOR=1 env var is set
- Colors now disabled when stdout is not a TTY (background processes)
- All color codes (CYAN, GREEN, BLUE, etc.) become empty strings when disabled
Impact:
- Clean log output when running in background
- Colors still work in interactive terminal sessions
- NO_COLOR=1 can be used to force disable colors
Problem:
- Many parallel runs crashed with: AttributeError: 'QuantTrace' object has no attribute 'controller'
- controller was only initialized in increment_factor_count(), not in __init__
- Code in quant_proposal.py line 66-67 accesses trace.controller before increment_factor_count() is called
Fix:
- Move self.controller = EnvController() to __init__ method
- controller is now available from the start
Also:
- Removed redundant controller initialization from increment_factor_count()
- This fixes crashes for ~50% of the parallel runs
Problem:
- All 50 parallel runs failed with: AttributeError: 'QuantTrace' object has no attribute 'get_factor_count'
- The _build_strategies_with_ai() method calls self.trace.get_factor_count()
- This method didn't exist in the QuantTrace class
Fix:
- Add get_factor_count() method to QuantTrace class
- Add increment_factor_count() method to track factor generation
- Call increment_factor_count() in running() step when factors are generated
- _build_strategies_with_ai() is already wrapped in try/except for safety
Now the parallel runs will work correctly.
Problem:
- Portfolio selection failed with 'Not enough valid overlapping data'
- Factors produce mostly NaN values or fail execution
- No diagnostics shown to user about why factors failed
Solution:
- Add detailed error tracking for each factor (timeout, no result, low values)
- Show summary of skipped factors with reasons
- Increase timeout to 2 minutes per factor
- Add fallback to show top factors by IC if portfolio fails
- Better progress messages showing valid value counts
- Handle symlink failures by copying data file instead
- Minimum 1000 non-NaN values required for factor to be included
Usage:
predix portfolio # Select top 10 from top 50
predix portfolio -n 100 # Select from top 100 candidates
predix portfolio -c 0.5 # Allow higher correlation (0.5)
Problem:
- When Qlib Docker backtest failed (result is None), the experiment was marked as failed
- However, the 'feedback' step still tried to call self.factor_summarizer.generate_feedback()
- This caused an IndexError or KeyError because the experiment object was invalid
- Run #9 crashed with: 'None of [key] are in the [axis_name]'
Solution:
- In feedback() method, check if exp.failed is True before generating feedback
- If failed, create a simple HypothesisFeedback with decision=False
- This allows the loop to continue instead of crashing
- Log a warning message with the failure reason
This fix works together with the _evaluate_factor_directly() fix in factor_runner.py
to ensure that even when Docker fails, the loop continues smoothly.
Problem:
- When factor evaluation timed out (5 min), result was undefined
- save_single_result(result) crashed with NameError
- factor.factor_name[:40] could fail if factor_name wasn't a string
Fix:
- Initialize result = None before try block
- Set result to failed EvalResult on exception
- Only call save_single_result() if result is not None
- Use getattr(factor, 'factor_name', 'unknown') for safe access
- Convert to string before slicing [:40]
Now the evaluator continues even when individual factors timeout.
New CLI commands:
- predix top [-n 20] [-m ic|sharpe]: Show top factors by IC/Sharpe
- predix evaluate [--top N] [--all] [--force]: Evaluate factors
Why 100 new factors mostly failed:
- 56 factors have IC=None (factor values are all NaN or constant)
- LLM generates code that doesn't work with EURUSD 1min data
- Common issues: volume=0 causes division by zero, wrong MultiIndex handling
- Only 346 of 501 factors have valid IC values
Working factors (Top 5):
1. daily_close_open_mom IC=0.255
2. daily_ret_log_1d IC=0.255
3. daily_ret_close_1d IC=0.255
4. daily_close_to_close_ret IC=0.255
5. daily_ret_vol_adj_1d IC=0.235
Usage:
predix top # Show top 20 by IC
predix top -n 50 # Show top 50
predix top -m sharpe # Sort by Sharpe
predix evaluate --all # Evaluate all NEW factors
predix evaluate --force # Re-evaluate ALL
Integrated predix_full_eval.py into the main Predix CLI.
New command:
predix evaluate [--top N] [--all] [--parallel P] [--force]
Features:
- Evaluates factors with full 1min data (2020-2026)
- Computes IC, Sharpe, Max DD, Win Rate
- Automatically skips already evaluated factors
- --force flag to re-evaluate all factors
Problem:
- predix_full_eval.py re-evaluated ALL factors every time
- 382 factors were evaluated even though 164 already had results
- Wasted 8+ minutes of computation time
Solution:
- Add scan_factors(skip_evaluated=True) parameter
- Load existing results from results/factors/*.json
- Skip factors that already have status='success' and valid IC
- Add --force/-f flag to override and re-evaluate ALL factors
Usage:
python predix_full_eval.py --top 100 # Only NEW factors
python predix_full_eval.py --force # Re-evaluate ALL
python predix_full_eval.py --all # All NEW factors
Now the evaluator resumes from where it left off.
- Create prompts/local/factor_discovery_v3.yaml
- Add working MultiIndex code pattern (unstack/stack)
- Show WRONG patterns to avoid (KeyError fixes)
- Add volume warning (FX volume often 0)
- Update prompt_loader to check v3 first
This should fix ~540 code crashes caused by MultiIndex errors.
Also answers: What happens when fin_quant runs now?
1. LLM generates factor code using NEW v3 prompt (with examples)
2. Code is executed and validated
3. Qlib backtest runs in Docker
4. Results saved to results/factors/ with:
- Full factor code
- Description
- IC, Sharpe, Win Rate, etc.
5. Results saved to SQLite database
