Longbridge temporarily unavailable for daily_data

Error message

Longbridge temporarily unavailable for daily_data

What it means

LongbridgeFetcher._fetch_raw_data guards on is_available_for_request('daily_data') and raises RuntimeError when its internal availability/circuit-breaker state says the source is temporarily down for that capability (e.g. consecutive recent failures or missing credentials made the fetcher mark itself unavailable). It is a skip-now signal, not a permanent failure.

Solutions

1. Wait for the availability window to reset (or restart the process) before retrying Longbridge for daily_data.
2. Fail over to the next US/HK-capable source (Finnhub/AlphaVantage/YFinance) via DataFetcherManager — the chain already handles this.
3. If it never becomes available, check Longbridge credentials/config so initialization marks the capability requestable.

Example fix

# before
if fetcher.is_available_for_request('daily_data') is not enforced at call site:
    df = fetcher.get_daily_data(code, ...)  # RuntimeError
# after
if fetcher.is_available_for_request('daily_data'):
    df = fetcher.get_daily_data(code, ...)
else:
    df = manager.get_daily_data(code, ...)  # failover chain

if fetcher.is_available_for_request('daily_data'):
    df = fetcher.get_daily_data(code, ...)
else:
    df = manager.get_daily_data(code, ...)  # chain skips unavailable sources

try:
    df = longbridge.get_daily_data(code, ...)
except RuntimeError as e:
    if 'temporarily unavailable' in str(e):
        df = manager.get_daily_data(code, ...)  # immediate failover; cooldown will reset

When it happens

Trigger: Calling get_daily_data on LongbridgeFetcher after earlier Longbridge failures tripped the availability state for daily_data, or when initialization (credentials/context) did not complete, so is_available_for_request returns False.

Common situations: Failover loops that retry Longbridge too soon after an outage; process kept alive across rate-limit windows; Longbridge creds partially configured so the fetcher is registered but not requestable.
