无法获取股票 {symbol} 的财务数据。已尝试所有数据源（MongoDB、AKShare、Tushare）均失败。

Error message

无法获取股票 {symbol} 的财务数据。已尝试所有数据源（MongoDB、AKShare、Tushare）均失败。

What it means

Raised by _estimate_financial_metrics in optimized_china_data when real financial metrics could not be retrieved from any backend (MongoDB cache, AKShare, Tushare). The module deliberately refuses to fabricate estimates and surfaces a ValueError naming the symbol.

Solutions

1. Verify the symbol is a valid A-share code (e.g. 600519.SH / 000001.SZ format expected by the module)
2. Check connectivity and try the AKShare fetch standalone; fix network/proxy
3. Configure Tushare credentials so the last fallback works
4. Populate the MongoDB cache for the symbol once data is available

Example fix

# before
report = _generate_fundamentals_report('XXXXXX', '2025-01-01')
# after
report = _generate_fundamentals_report('600519.SH', '2025-01-01')

from tradingagents.config.database_manager import get_database_manager
try:
    get_database_manager()
except Exception:
    raise SystemExit('Backends unavailable; fix MongoDB/AKShare/Tushare first')

try:
    report = _generate_fundamentals_report(symbol, date)
except ValueError as e:
    if '财务数据' in str(e):
        report = cached_report(symbol) or 'Financial data unavailable'
    else:
        raise

When it happens

Trigger: Generating a fundamentals report (_generate_fundamentals_report) for a symbol with no data in MongoDB, an AKShare call that fails/times out, and no valid Tushare token — all three failing in sequence.

Common situations: Obscure/delisted A-share tickers, AKShare network issues, Tushare token missing or rate-limited, MongoDB cache empty for that symbol.
