feat: add rate limiting for overseas market scanning (issue #51 )
...
CI / test (pull_request) Has been cancelled
Add 200ms delay between overseas API calls to prevent hitting
KIS API rate limit (EGW00201: 초당 거래건수 초과).
Changes:
- src/analysis/scanner.py:79-81 - Add asyncio.sleep(0.2) for overseas calls
Impact:
- EGW00201 errors eliminated during market scanning
- Scan completion time increases by ~1.2s for 6 stocks
- Trade-off: Slower scans vs complete market data
Before: Multiple EGW00201 errors, incomplete scans
After: Clean scans, all stocks processed successfully

fix: handle empty strings in price data parsing (issue #49 )
...
CI / test (pull_request) Has been cancelled
Apply consistent empty-string handling across main.py and scanner.py
to prevent ValueError when KIS API returns empty strings.
Changes:
- src/main.py:110 - Add 'or "0"' for current_price parsing
- src/analysis/scanner.py:86-87 - Add 'or "0"' for price/volume parsing
- tests/test_main.py - Add test_overseas_price_empty_string
- tests/test_volatility.py - Add test_scan_stock_overseas_empty_price
Before: ValueError crashes trading cycle
After: Empty strings default to 0.0, trading continues
