Invalid symbol
A symbol is not in TICKER or MIC:TICKER form.
"type": "https://ohlc.io/problems/invalid-symbol"
Why it happens
- Extra characters, such as
$AAPL, or an exchange name instead of a MIC. - Leading or trailing whitespace, such as
AAPL%20; a space inside a ticker (BAC PRL) is allowed.
How to fix it
- Use
MIC:TICKER, for exampleXNAS:AAPL, or a bare ticker. See symbols.
