Root cause analysis revealed 3 critical issues causing EGW00201 errors:
1. **Hash key bypass** - _get_hash_key() made API calls without rate limiting
- Every order made 2 API calls but only 1 was rate-limited
- Fixed by adding rate_limiter.acquire() to _get_hash_key()
2. **Scanner concurrent burst** - scan_market() launched all stocks via asyncio.gather
- All tasks queued simultaneously creating burst pressure
- Fixed by adding Semaphore(1) for fully serialized scanning
3. **RPS too aggressive** - 5.0 RPS exceeded KIS API's real ~2 RPS limit
- Lowered to 2.0 RPS (500ms interval) for maximum safety
Changes:
- src/broker/kis_api.py: Add rate limiter to _get_hash_key()
- src/analysis/scanner.py: Add semaphore-based concurrency control
- New max_concurrent_scans parameter (default 1, fully serialized)
- Wrap scan_stock calls with semaphore in _bounded_scan()
- Remove ineffective asyncio.sleep(0.2) from scan_stock()
- src/config.py: Lower RATE_LIMIT_RPS from 5.0 to 2.0
- tests/test_broker.py: Add 2 tests for hash key rate limiting
- tests/test_volatility.py: Add test for scanner concurrency limit
Results:
- EGW00201 errors: 10 → 0 (100% elimination)
- All 290 tests pass
- 80% code coverage maintained
- Scanner still handles unlimited stocks (just serialized for API safety)

Reduce RATE_LIMIT_RPS from 10.0 to 5.0 to prevent "초당 거래건수를
초과하였습니다" (EGW00201) errors from KIS API.
Docker logs showed this was the most frequent error (70% of failures),
occurring when multiple stocks are scanned rapidly.
Changes:
- src/config.py: RATE_LIMIT_RPS 10.0 → 5.0
- .env.example: Update default and add explanation comment
Trade-off: Slower API throughput, but more reliable operation.
Can be tuned per deployment via environment variable.
Fixes: #43

Add ALPHA_VANTAGE_API_KEY and NEWSAPI_KEY for backward compatibility
with existing .env configurations.
Fixes test failures in test_volatility.py where Settings validation
rejected extra fields from environment variables.

Add objective external data sources to enhance trading decisions beyond
market prices and user input.
## New Modules
### src/data/news_api.py
- News sentiment analysis with Alpha Vantage and NewsAPI support
- Sentiment scoring (-1.0 to +1.0) per article and aggregated
- 5-minute caching to minimize API quota usage
- Graceful degradation when APIs unavailable
### src/data/economic_calendar.py
- Track major economic events (FOMC, GDP, CPI)
- Earnings calendar per stock
- Event proximity checking for high-volatility periods
- Hardcoded major events for 2026 (no API required)
### src/data/market_data.py
- Market sentiment indicators (Fear & Greed equivalent)
- Market breadth (advance/decline ratios)
- Sector performance tracking
- Fear/Greed score calculation
## Integration
Enhanced GeminiClient to seamlessly integrate external data:
- Optional news_api, economic_calendar, and market_data parameters
- Async build_prompt() includes external context when available
- Backward-compatible build_prompt_sync() for existing code
- Graceful fallback when external data unavailable
External data automatically added to AI prompts:
- News sentiment with top articles
- Upcoming high-impact economic events
- Market sentiment and breadth indicators
## Configuration
Added optional settings to config.py:
- NEWS_API_KEY: API key for news provider
- NEWS_API_PROVIDER: "alphavantage" or "newsapi"
- MARKET_DATA_API_KEY: API key for market data
## Testing
Comprehensive test suite with 38 tests:
- NewsAPI caching, sentiment parsing, API integration
- EconomicCalendar event filtering, earnings lookup
- MarketData sentiment and breadth calculations
- GeminiClient integration with external data sources
- All tests use mocks (no real API keys required)
- 81% coverage for src/data module (exceeds 80% requirement)
## Circular Import Fix
Fixed circular dependency between gemini_client.py and cache.py:
- Use TYPE_CHECKING for imports in cache.py
- String annotations for TradeDecision type hints
All 195 existing tests pass. No breaking changes to existing functionality.
