Overview
Twelve Data Public Scraper

Troubleshooting
Why am I getting fewer records than my maxItems setting?
The Actor stops when it has fetched the number of records you requested or when it has exhausted the available public data. If the endpoint returns fewer results than your limit, the run ends early.
Why do some requests return empty data?
Some symbols or indicators may not be available on the public endpoints. Check that the symbol is valid and actively traded on a supported exchange.
The Actor is running slowly. Is that normal?
The Actor makes sequential requests to respect Twelve Data's servers. Large historical pulls take longer. Reduce your maxItems if you need faster, smaller runs.
I see a 'request failed' error in the log.
A temporary network issue or an unavailable endpoint can cause this. The Actor will retry automatically. If it persists, check Twelve Data's service status.
