No data was returned for any symbol

Error message

No data was returned for any symbol

What it means

Finviz equity profile fetcher raises EmptyDataError('No data was returned for any symbol') after iterating every symbol in the comma-separated query. Each per-symbol attempt returned neither a result nor an error message collected in `messages`, so the provider cannot distinguish 'bad symbol' from 'no data' and reports an empty dataset.

Solutions

1. Test each symbol individually to identify which ones return nothing
2. Strip whitespace and drop empty entries from the comma-separated symbol string before querying
3. Use Finviz-recognized tickers (no exchange suffixes, no dots where Finviz expects dashes)
4. If partial results are acceptable, split the request per symbol and skip the empties

Example fix

# before
result = await obb.equity.profile(symbol="FOO,BAR,ZZZZZZ")  # all invalid -> EmptyDataError

# after
raw = "FOO,BAR,ZZZZZZ"
symbols = ",".join(s.strip() for s in raw.split(",") if s.strip())
result = await obb.equity.profile(symbol=symbols)

def clean_symbols(raw: str) -> str:
    return ",".join(s.strip() for s in raw.split(",") if s.strip())

symbols = clean_symbols(query_symbol)
assert symbols, "symbol string is empty after cleaning"

def is_finviz_symbol_list(s: str) -> bool:
    parts = [p for p in s.split(",") if p.strip()]
    return len(parts) > 0 and all(p.strip().isascii() and 1 <= len(p.strip()) <= 6 for p in parts)

from openbb_core.provider.abstract.errors import EmptyDataError

try:
    profiles = await FinvizEquityProfileFetcher.transform_query(...)
except EmptyDataError:
    profiles = []  # none of the tickers resolved on Finviz

When it happens

Trigger: Passing a symbols string where none of the tickers resolve on Finviz (e.g. 'FOOBAR,INVALID'); all symbols returning empty profile rows; symbols with whitespace or exchange suffixes (e.g. 'BRK.B') that Finviz rejects silently.

Common situations: Batch jobs feeding unvalidated ticker lists from a database; using non-US or delisted tickers against a US-screener-only data source; trailing commas producing empty symbol strings.
