}CMF API FAQ
What does the CMF API return?
It returns value, plus a timestamp for the request. Results are JSON.
Is the latest CMF value final?
No. The newest value belongs to the candle still forming and can change until it closes. Add backtrack=1 to read the last closed candle.
Which CMF settings can I change?
You can set period. See the parameters table above for defaults.
Can I get CMF for US stocks?
Yes. Use exchange=stocks with a ticker such as AAPL. US stocks are included on the Pro plan and above.
