Error message

Failed to get data from Alpha Vantage after {max_retries} attempts

What it means

Raised as AlphaVantageAPIError after the retry loop finishes without returning data and without a more specific exception — the theoretical 'all retries exhausted' fallback at the end of _make_api_request. In practice it appears when every attempt hits a path that continues rather than raises (e.g. benign rate-limit Notes exhausted the budget).

Solutions

1. Treat it like a rate-limit/connectivity failure: back off substantially and retry the whole request later
2. Increase retry_delay and max_retries so throttled attempts eventually succeed
3. Reduce concurrent Alpha Vantage usage or upgrade the key plan

Example fix

# before
max_retries, retry_delay = 1, 0
# after
max_retries, retry_delay = 5, 12  # survive throttled windows

from tradingagents.dataflows.providers.us.alpha_vantage_common import AlphaVantageAPIError
for delay in (60, 300, 900):
    try:
        data = _make_api_request(params); break
    except AlphaVantageAPIError as e:
        if 'after' in str(e) and 'attempts' in str(e):
            time.sleep(delay)
        else:
            raise

When it happens

Trigger: max_retries attempts all take the `continue` branch (rate-limit Note with wait then retry) and the loop ends, reaching the trailing raise instead of the dedicated rate-limit error.

Common situations: Tuning max_retries/retry_delay down so the loop drains on retryable conditions; concurrent callers sharing a quota so every attempt is throttled.
