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
