What is VIDYA?

The Variable Index Dynamic Average, from Tushar Chande, adjusts an EMA's speed according to the ratio of short-term to long-term volatility.

VIDYA API FAQ

What does the VIDYA API return?

It returns value, plus a timestamp for the request. Results are JSON.

Is the latest VIDYA 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 VIDYA settings can I change?

You can set short_period, long_period, alpha. See the parameters table above for defaults.

Can I get VIDYA for US stocks?

Yes. Use exchange=stocks with a ticker such as AAPL. US stocks are included on the Pro plan and above.
