feat: Implement comprehensive PDF report generation system
🎯 Major Features Added: - Automatic PDF generation after each analysis - Playwright-based PDF engine with WeasyPrint fallback - Cross-platform compatibility (no system dependencies) - Professional structured reports matching terminal output 📋 Report Structure: - I. Analyst Team Reports (Market/Social/News/Fundamentals) - II. Research Team Decision (Bull/Bear/Research Manager) - III. Trading Team Plan (Trader recommendations) - IV. Risk Management Team Decision (Risk analysts) - V. Portfolio Manager Decision (Final decision) 🏗️ Architecture: - New tradingagents/reports/ module with organized structure - generators/: PDF generation engines - formatters/: Report structure and formatting - converters/: Content conversion utilities - Comprehensive documentation and error handling 🔧 Technical Details: - Added playwright>=1.40.0 dependency - Integrated into CLI workflow (cli/main.py) - Rich HTML export with professional styling - Automatic file generation: analysis_report.pdf + .html backup - File sizes: ~900KB PDF, ~45KB HTML ✅ Benefits: - Zero manual intervention required - High-quality professional reports - Structured content preservation - Robust error handling and fallbacks

# TradingAgents Reports Module
|
||||
|
||||
This module provides comprehensive report generation capabilities for TradingAgents analysis results.
|
||||
|
||||
## Structure
|
||||
|
||||
```
|
||||
tradingagents/reports/
|
||||
├── __init__.py # Main module interface
|
||||
├── README.md # This documentation
|
||||
├── generators/ # Report generators

|
||||
├── __init__.py
|
||||
└── html_converter.py # Rich console to HTML conversion
|
||||
```
|
||||
|
||||
## Features
|
||||
|
||||
### 🎯 **Automatic PDF Generation**
|
||||
- Generates PDF reports automatically after each analysis
|
||||
- Uses Playwright as primary engine (cross-platform, no system dependencies)
|
||||
- WeasyPrint fallback for compatibility
|
||||
- Professional styling with proper sections and formatting
|
||||
|
||||
### 📋 **Structured Reports**
|
||||
Reports follow the exact terminal structure:
|
||||
1. **I. Analyst Team Reports** - Market/Social/News/Fundamentals analysts
|
||||
2. **II. Research Team Decision** - Bull/Bear/Research Manager analysis
|
||||
3. **III. Trading Team Plan** - Trader's strategic recommendations
|
||||
4. **IV. Risk Management Team Decision** - Risk analysts' perspectives
|
||||
5. **V. Portfolio Manager Decision** - Final investment decision
|
||||
|
||||
### 🎨 **Rich Formatting**
|
||||
- Color-coded sections matching terminal output
|
||||
- Professional panels and styling
|
||||
- Markdown content conversion
|
||||
- Responsive layout for different content types
|
||||
|
||||
## Usage
|
||||
|
||||
The reports module is automatically integrated into the main CLI workflow. No manual intervention required.
|
||||
|
||||
```python
|
||||
from tradingagents.reports import TradingReportPDFGenerator
|
||||
|
||||
# Used automatically in cli/main.py
|
||||
generator = TradingReportPDFGenerator()
|
||||
pdf_path = generator.generate_pdf(analysis_data, ticker, date)
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
PDF generation can be configured in `tradingagents/default_config.py`:
|
||||
|
||||
```python
|
||||
"pdf_generation": {
|
||||
"enabled": True,
|
||||
"output_dir": "results",
|
||||
"page_format": "A4",
|
||||
"margin": "2cm",
|
||||
"font_family": "Arial, sans-serif",
|
||||
"font_size": "12pt",
|
||||
"auto_generate": True,
|
||||
}
|
||||
```
|
||||
|
||||
## Dependencies
|
||||
|
||||
- **playwright**: Primary PDF generation engine
|
||||
- **weasyprint**: Fallback PDF generation (optional)
|
||||
- **rich**: Terminal styling and content formatting
|
||||
- **jinja2**: HTML templating
|
||||
|
||||
## Output
|
||||
|
||||
Generated files are saved to:
|
||||
- `results/{ticker}/{date}/analysis_report.pdf` - Main PDF report
|
||||
- `results/{ticker}/{date}/analysis_report.html` - HTML backup
|
||||
|
||||
Example file sizes:
|
||||
- PDF: ~900KB (comprehensive analysis with all sections)
|
||||
- HTML: ~45KB (structured content backup)
