### Open Source vs. Closed Source

**🟢 OPEN SOURCE (Public on GitHub - FULLY WORKING):**
- `rdagent/` - Core framework (ALL components)
- `models/standard/` - Base models (XGBoost, LightGBM)
- `prompts/standard_prompts.yaml` - Base prompts
- `web/` - Dashboards
- `test/` - ALL tests (integration, unit, security)
- `rdagent/components/coder/rl/` - RL Trading System (with fallback)
- `rdagent/components/backtesting/protections/` - Trading Protection System
- `scripts/` - Utility scripts

**GitHub users get:**
✅ Full working trading system
✅ RL Trading with graceful fallback (no stable-baselines3 needed)
✅ Protection Manager (drawdown, cooldown, stoploss guard)
✅ Backtesting Engine with RL support
✅ CLI commands (`fin_quant`, `rl_trading`, etc.)
✅ Web and CLI dashboards
✅ All 200+ integration tests

**🔒 CLOSED SOURCE (Local Only - NOT on GitHub):**
- `models/local/` - Your improved models (Transformer, TCN, PatchTST, CNN+LSTM)
- `prompts/local/` - Your improved prompts (v2.0 optimized)
- `.env` - API keys
- `results/` - Backtest results
- `git_ignore_folder/` - Trading data
- `QWEN.md`, `TODO.md` - Internal docs

**Protection:**
- `.gitignore` excludes all `local/` directories
- Your competitive edge (alpha) stays private
- Framework is open, but your best models/prompts are closed

### Open Source Fallback Strategy

**For users without stable-baselines3:**
The RL system provides graceful degradation:
- ❌ No stable-baselines3 → Uses simple momentum-based fallback
- ✅ Still fully functional: CLI, backtesting, protections work
- ✅ No errors or broken features
- ✅ Clear warning message with installation instructions

**For users without LLM (llama.cpp):**
- Factor evolution degrades gracefully
- System still works with standard models
- Clear error messages for missing LLM

**PRINCIPLE:** Every GitHub user MUST be able to run the full system. Missing optional components should never break the project.

```

## Development Conventions

### Language Policy

**ALL code comments and documentation MUST be in English.**

❌ **Wrong (German):**
```python
# Inspiriert von: TradingAgents
# Berechnet den Sharpe Ratio
# Achtung: Division durch Null möglich!
# Hinweis: Diese Funktion ist experimentell
```

✅ **Correct (English):**
```python
# Inspired by: TradingAgents
# Calculates the Sharpe ratio
# Warning: Division by zero possible!
# Note: This function is experimental
```

**Rationale:**
- International collaboration
- Better searchability
- Professional codebase
- Consistent with commit messages (also English-only)

**Enforcement:**
- All new code must have English comments
- Existing German comments should be translated when modified
- PRs with German comments will be rejected

### Code Style

- **Line length:** 120 characters (configured in pyproject.toml)
- **Type hints:** Required for all public functions
- **Docstrings:** Google style for public APIs
- **Imports:** Sorted automatically with isort

### Testing Practices
- Unit tests in `test/` directory
- Test files named `test_*.py`
- Use pytest fixtures for common setup
- Mock external APIs (LLM, yfinance)
- Minimum 80% coverage target

### Commit Conventions
```bash
git commit --author="TPTBusiness <tpt.requests@pm.me>" -m "type: description"

# Types:
# - feat: New feature
# - fix: Bug fix
# - docs: Documentation
# - style: Formatting
# - refactor: Code restructuring

        pass
```

### Backtesting Module Usage

```python
from rdagent.components.backtesting import (
    FactorBacktester,
    ResultsDatabase,
    PortfolioOptimizer,
    AdvancedRiskManager
)

# Run backtest
backtester = FactorBacktester()
metrics = backtester.run_backtest(
    factor_values=factor_series,
    forward_returns=forward_returns,
    factor_name="MyFactor"
)

# Save to database
db = ResultsDatabase()
db.add_backtest("MyFactor", metrics)

# Query top factors
top = db.get_top_factors('sharpe_ratio', limit=20)

# Portfolio optimization
optimizer = PortfolioOptimizer()
weights = optimizer.mean_variance(expected_returns, cov_matrix)

# Risk management
risk_manager = AdvancedRiskManager()
report = risk_manager.generate_risk_report(returns, weights)
```

### Key Metrics

| Metric | Target | Minimum |
|--------|--------|---------|
| IC (Information Coefficient) | > 0.05 | > 0.02 |
| Sharpe Ratio | > 2.0 | > 1.0 |
| Max Drawdown | < 15% | < 25% |
| Win Rate | > 55% | > 45% |
| Annualized Return | > 10% | > 5% |

### Language Policy

**ALL commit messages MUST be in English.**

❌ **Wrong (German):**
```bash
git commit -m "feat: Neue Funktion hinzugefügt"
git commit -m "fix: Fehler behoben"
git commit -m "chore: QWEN.md zu .gitignore hinzugefügt"
```

✅ **Correct (English):**
```bash
git commit -m "feat: Add new feature"
git commit -m "fix: Fix bug"
git commit -m "chore: Add QWEN.md to .gitignore"
```

### Pre-Commit Checklist

**BEFORE every commit, you MUST:**

1. **Run `git status`** and verify:
   - Only intended files are staged
   - No generated files (.qwen/, results/, *.db, etc.)
   - No sensitive data (.env, API keys, etc.)

2. **Check .gitignore** is working:
   ```bash
   git status
   # Verify .qwen/, results/, *.db are NOT shown
   ```

3. **Review staged changes:**
   ```bash
   git diff --staged
   # Review what will be committed
   ```

4. **Run tests** (if applicable):
   ```bash
   pytest test/backtesting/ -v
   # Ensure all tests pass
   ```

### Commit Message Format

Use [Conventional Commits](https://www.conventionalcommits.org/):

```

If you accidentally commit any of these:

```bash
# Remove from last commit (keeps files locally)
git reset HEAD~1

# Or remove from tracking
git rm -r --cached .qwen/
git commit -m "chore: Remove .qwen/ from tracking"
```

### Fixing Past Commits

**To fix the last 3-5 commits:**

```bash
# For last 5 commits
git rebase -i HEAD~5

# In the editor, change 'pick' to 'reword' for commits to rename
# Save and close
# Write new English message for each commit
```

**To fix older commits (advanced):**

```bash
# Find the commit hash
git log --oneline

# Start rebase from that commit
git rebase -i <commit-hash>^

## Implementation Guide: Prompts & Models

### Using the Prompt Loader

**Auto-Load Prompts (Local First):**

```python
from rdagent.components.loader import load_prompt

# Load factor discovery prompt
# Automatically loads from prompts/local/ if exists!
prompt = load_prompt("factor_discovery")

# Load specific section
system_prompt = load_prompt("factor_discovery", section="system")
user_prompt = load_prompt("factor_discovery", section="user")

# Force local only (raise error if not found)
prompt = load_prompt("factor_discovery", local_only=True)

# List available prompts
from rdagent.components.loader import list_available_prompts
available = list_available_prompts()
print(f"Standard: {available['standard']}")
print(f"Local: {available['local']}")
```

**Priority:**
1. `prompts/local/factor_discovery_v2.yaml` (loaded first if exists)
2. `prompts/local/factor_discovery.yaml`
3. `prompts/standard_prompts.yaml` (fallback)

---

### Using the Model Loader

**Auto-Load Models (Local First):**

```python
from rdagent.components.model_loader import load_model

# Load XGBoost model
# Automatically loads from models/local/ if exists!
model_factory = load_model("xgboost_factor")

# Create model instance
model = model_factory(max_depth=8, learning_rate=0.03)

# Train
model.fit(X_train, y_train, epochs=50, batch_size=64)

# Predict
predictions = model.predict(X_test)

# Save/Load
model.save("models/my_model.pth")
model.load("models/my_model.pth")
```

**Available Models:**

| Model | Location | Use Case |
|-------|----------|----------|
| `xgboost_factor` | `models/standard/` | Tabular data, fast training |
| `lightgbm_factor` | `models/standard/` | Large datasets, faster than XGBoost |
| `transformer_factor` | `models/local/` | Time-series, long-range dependencies |
| `tcn_factor` | `models/local/` | Multi-scale patterns |
| `patchtst_factor` | `models/local/` | **SOTA** for time-series forecasting |
| `cnn_lstm_hybrid` | `models/local/` | Complex pattern recognition |

**Priority:**
1. `models/local/{name}_v2.py` (loaded first if exists)
2. `models/local/{name}.py`
3. `models/standard/{name}.py` (fallback)

---

### Creating Your Improved Prompts

**Step 1: Create Local Prompt**

```bash
mkdir -p prompts/local
nano prompts/local/factor_discovery_v3.yaml
```

**Step 2: Add Your Improvements**

```yaml
# prompts/local/factor_discovery_v3.yaml

factor_discovery:
  system: |-
    YOUR IMPROVED SYSTEM PROMPT HERE
    
    Add your proprietary insights:
    - Specific EURUSD patterns you've discovered
    - Your unique factor formulas
    - Custom session filters
    - Proprietary risk management rules
    
  user: |-
    YOUR IMPROVED USER PROMPT HERE
```

**Step 3: Test**

```python
from rdagent.components.loader import load_prompt

# Auto-loads your v3!
prompt = load_prompt("factor_discovery")
```

---

### Creating Your Improved Models

**Step 1: Create Local Model**

```bash
mkdir -p models/local
nano models/local/my_optimized_model.py
```

**Step 2: Implement Model**

```python
# models/local/my_optimized_model.py
"""
My Optimized Model v1.0
Better than standard with custom improvements.
"""

import torch
import torch.nn as nn

class MyOptimizedModel(nn.Module):
    def __init__(self, **params):
        super().__init__()
        # Your custom architecture
        pass
    
    def forward(self, x):
        # Your custom forward pass
        pass

def create_my_optimized_model(**params):
    """Factory function."""
    return MyOptimizedModel(**params)
```

**Step 3: Test**

```python
from rdagent.components.model_loader import load_model

# Auto-loads your optimized model!
model_factory = load_model("my_optimized_model")
model = model_factory()
```

---

### Backup Your Private Assets

**Backup Prompts & Models to Private Repo:**

```bash
# Create private repo on GitHub: predix-private-assets

# Clone private repo
cd ~/Dev
git clone git@github.com:TPTBusiness/predix-private-assets.git

# Copy local assets
cp -r ~/Predix/prompts/local/* ~/predix-private-assets/prompts/
cp -r ~/Predix/models/local/* ~/predix-private-assets/models/

# Commit to private repo
cd ~/predix-private-assets
git add .
git commit -m "Backup: prompts v2, models (Transformer, TCN, PatchTST, CNN+LSTM)"
git push
```

**Auto-Sync Script:**

```bash
# ~/Predix/sync_private.sh
#!/bin/bash
echo "Syncing private assets..."
rsync -av prompts/local/ ~/predix-private-assets/prompts/
rsync -av models/local/ ~/predix-private-assets/models/
cd ~/predix-private-assets && git add . && git commit -m "Auto-sync $(date)" && git push
echo "Done!"
```

---

### Security Best Practices

**What to Keep Private:**

✅ Your proprietary model architectures
✅ Optimized prompt templates
✅ Best-performing factors
✅ Evolution weights
✅ Trade secrets & alpha-generating logic

**What NOT to Commit:**

❌ Anything in `prompts/local/`
❌ Anything in `models/local/`
❌ `.env` (API keys)
❌ `results/` (backtest performance)
❌ `git_ignore_folder/` (trading data)

**Verify Before Committing:**

```bash
# Check what will be committed
git status
git diff --staged

# Verify .gitignore is working
git status
# Should NOT show prompts/local/, models/local/, .env, results/
```

---

## Development Guidelines for AI Assistant

### 🌍 CRITICAL: Open Source Compatibility

**BEFORE implementing ANY feature, ask yourself:**

1. **Can a GitHub user run this without our local files?**
   - ✅ YES → Good, proceed
   - ❌ NO → Add fallback or graceful degradation

2. **Does this break if optional dependencies are missing?**
   - Example: `stable-baselines3`, `llama.cpp`, `Ollama`
   - Solution: Try/except with clear warning messages

3. **Is this feature documented for external users?**
   - Update README.md with usage instructions
   - Ensure installation guide covers all dependencies

**PRINCIPLE:** The project on GitHub MUST be fully functional for users. Our closed-source assets (`models/local/`, `prompts/local/`, `.env`) are ENHANCEMENTS, not requirements.

### ⚠️ MANDATORY Rules for ALL Development

**When implementing NEW features or making SIGNIFICANT changes, you MUST:**

#### 1. 📝 Update QWEN.md

**When:** Every time you add a new feature, module, or change existing architecture.

**What to update:**
- Architecture section (if structure changes)
- Important Files section
- Testing section
- Key Metrics (if targets change)
- Project Status
- Next Steps

**Example:**
```markdown
### Architecture
├── rdagent/
│   └── components/
│       └── backtesting/
│           └── protections/          # NEW: Trading protection system
│               ├── base.py
│               ├── max_drawdown.py
│               └── protection_manager.py
```

#### 2. 📖 Update README.md

**When:** Every user-facing feature change or major update.

**What to update:**
- Features list
- Installation instructions
- Usage examples
- Configuration examples

**Keep it user-focused:**
```markdown
## Features
- ✅ Trading Protection System (NEW)
  * Automatic drawdown protection
  * Cooldown periods after losses
  * Stoploss cluster detection
```

#### 3. 📦 Update requirements.txt

**When:** Adding new dependencies or removing unused ones.

**What to update:**
- `requirements.txt` (main dependencies)
- `requirements/lint.txt` (dev dependencies)
- `requirements/test.txt` (test dependencies)

**Example:**
```bash
# If you add a new library
echo "new-library==1.0.0" >> requirements.txt

# If you add a new test dependency
echo "pytest-mock" >> requirements/test.txt
```

#### 4. ✅ Extend Tests

**When:** EVERY time you add new code.

**Rule:** New features MUST have tests with >80% coverage.

**What to create:**
- Unit tests in `test/` directory
- Integration tests in `test/integration/`
- Update existing tests if behavior changed

**Test structure:**
```python
# test/feature_type/test_new_feature.py
"""Tests for New Feature"""

class TestNewFeature:
    """Test new feature thoroughly."""
    
    def test_basic_functionality(self): ...
    def test_edge_cases(self): ...
    def test_error_handling(self): ...
    def test_integration_with_existing(self): ...
```

**Update integration tests:**
```python
# Add to test/integration/test_all_features.py
class TestNewFeature:
    """Test new feature integration."""
    
    def test_imports(self): ...
    def test_initialization(self): ...
    def test_full_workflow(self): ...
```

#### 5. 🔄 Pre-Commit Checklist

**BEFORE every commit with new features:**

```bash
# 1. Run ALL tests
pytest test/ -v

# 2. Run integration tests
pytest test/integration/test_all_features.py -v

# 3. Check test coverage
pytest --cov=rdagent.components.new_module -v

# 4. Run security scan
bandit -r rdagent/ -c .bandit.yml

# 5. Verify tests updated
git status
# Should show test files modified
```

### Documentation Priority Order

1. **QWEN.md** - Internal AI assistant context (UPDATE ALWAYS)
2. **Test files** - Code documentation through tests (MANDATORY)
3. **README.md** - User-facing documentation (UPDATE for user-visible changes)
4. **requirements.txt** - Dependencies (UPDATE when adding libraries)
5. **Inline code comments** - English only (ALWAYS)

### Example Workflow: Adding New Feature

```
1. Plan feature
   ↓
2. Implement code
   ↓
3. Write unit tests (test/...)
   ↓
4. Write integration tests (test/integration/...)
   ↓
5. Run ALL tests → Must pass
   ↓
6. Update QWEN.md ← MANDATORY
   ↓
7. Update README.md (if user-visible)
   ↓
8. Update requirements.txt (if new deps)
   ↓
9. Commit with clear message
   ↓
10. Pre-commit hooks run automatically
    ↓
11. Push to remote
```

### Penalties for Not Following Rules

**If you forget to update:**
- ❌ Missing tests → Code cannot be committed (pre-commit blocks)
- ❌ Missing QWEN.md update → Next AI assistant will work with outdated context
- ❌ Missing README update → Users won't understand new features
- ❌ Missing requirements.txt → Installation will fail

**Remember:** These rules ensure:
1. Code quality through tests
2. AI assistant has current context
3. Users understand changes
4. Dependencies are tracked
