I'm using Tiingo to get historical data on US stocks & ETFs (in15-minute bars).
It seems to be working on some symbols (like A ) but failing on others (e.g. AA ).
It works on some ETF's (e.g. SPY) and fails on others (such as QQQ).

1) Any ideas?
2) Could someone recommend another data provider that can supply historical 15-minute bars on US symbols?

I don't know what "failing" means as it's too vague. Maybe you have an idea or an error message? For troubleshooting ideas, check out the documentation > Issues and Limitations.

Thank you, Eugene. Here is the exact error message I get:'

here is a chart showing the chart for the symbol A:

There is no data for the symbol AA

Thanks. "Data parsing error. Symbol: xxx, LineNumber: -1, String: Message: Invalid JSON primitive: You..." is explained in posts #25 and #27 here:

Tiingo static and fundamental data provider

Issues and Limitations

Bottom line: upgrade to a paid plan to make more than 500 requests per hour and be able to download more than 500 symbols per month (or whatever limitations are imposed now).
