## 🚀 Quick Start
### Installation
```bash
# Clone or navigate to project
cd ib-sec
# Install dependencies
pip install -e .
# Verify installation
ib-sec-fetch --help
ib-sec-analyze --help
```
### Configuration
Create `.env` file:
```env
QUERY_ID=your_query_id_here
TOKEN=your_token_here
```
### Basic Usage
```bash
# 1. Fetch data
ib-sec-fetch --start-date 2025-01-01 --end-date 2025-10-05
# 2. Run analysis
ib-sec-analyze data/raw/U1234567_2025-01-01_2025-10-05.csv --all
# 3. View results in console
```
### Programmatic Usage
```python
from ib_sec_mcp import FlexQueryClient
from ib_sec_mcp.analyzers import PerformanceAnalyzer
from ib_sec_mcp.core.parsers import CSVParser
# Fetch data
client = FlexQueryClient(query_id="...", token="...")
statement = client.fetch_statement(start_date, end_date)
# Parse
account = CSVParser.to_account(statement.raw_data, start_date, end_date)
# Analyze
analyzer = PerformanceAnalyzer(account=account)
results = analyzer.analyze()
print(results)
```

## 🎯 Design Patterns Used
### Template Method (BaseAnalyzer)
```python
class BaseAnalyzer(ABC):
@abstractmethod
def analyze(self) -> AnalysisResult:
pass
class PerformanceAnalyzer(BaseAnalyzer):
def analyze(self) -> AnalysisResult:
# Implementation
return self._create_result(...)
```
### Strategy (Reports)
```python
class BaseReport(ABC):
@abstractmethod
def render(self) -> str:
pass
class ConsoleReport(BaseReport):
def render(self) -> str:
# Console-specific rendering
```
### Factory (Parsers)
```python
account = CSVParser.to_account(csv_data, from_date, to_date)
```
### Builder (Portfolio)
```python
portfolio = Portfolio.from_accounts(accounts, base_currency="USD")
```
---
## 🔧 Development Workflow
### Adding New Features
1. **New Analyzer**
```bash
# Use custom command
/add-analyzer Sharpe "Calculate Sharpe ratio"
```
2. **Update Context**
```bash
# Press # in Claude Code
# "New analyzers must calculate annualized metrics"
```
3. **Format & Lint**
```bash
black ib_sec_mcp tests
ruff check ib_sec_mcp tests
mypy ib_sec_mcp
```
### Testing (Future)
```bash
# Run tests
pytest
# With coverage
pytest --cov=ib_sec_mcp --cov-report=html
# Specific test
pytest tests/test_analyzers/test_performance.py
```

## 📊 Migration from Legacy Scripts
### Before (Legacy Scripts)
```
ib-sec/
├── analyze_performance.py # Standalone script
├── trading_cost_analysis.py # Standalone script
├── phantom_income_tax_analysis.py
├── bond_analysis.py
├── interest_rate_scenario_analysis.py
└── comprehensive_summary_report.py
```
**Issues**:
- ❌ Code duplication
- ❌ No type safety
- ❌ Hard to test
- ❌ No multi-account support
- ❌ Monolithic structure
### After (New Library)
```
ib_sec_mcp/
├── analyzers/
│ ├── performance.py # Modular
│ ├── cost.py # Reusable
│ ├── bond.py # Type-safe
│ ├── tax.py # Testable
│ └── risk.py # Extensible
```
**Benefits**:
- ✅ Modular architecture
- ✅ Type safety (Pydantic)
- ✅ Easy to test
- ✅ Multi-account support
- ✅ CLI + programmatic API
