� Problem Fixed:
- Remove duplicate get_ticker() function in main.py that had no parameters
- This function was overriding the correct get_ticker(market=None) from utils.py
- Caused TypeError: get_ticker() takes 0 positional arguments but 1 was given
✅ Solution:
- Delete old get_ticker() function from main.py (line 506-508)
- Keep only the correct get_ticker(market=None) function in utils.py
- Function now properly accepts market parameter for market-specific validation
� Test Results:
- Function signature: (market=None) -> str ✅
- Function location: cli/utils.py line 67 ✅
- No import conflicts ✅
- CLI startup working ✅
- Market selection working ✅
Now users can successfully:
1. Select market (US Stock or China A-Share)
2. Enter ticker with market-specific validation
3. Continue with analysis workflow
The CLI now properly handles market selection and ticker input without parameter errors.
