FAQ

Questions Historical Volatility Calculator owners ask.

  • 01

    What is the difference between simple returns and the returns used here?

    This capability uses logarithmic returns (ln(close/prev_close)) to ensure returns are additive and better represent continuous price movements.

  • 02

    How is the volatility annualized?

    The standard deviation of log returns is multiplied by the square root of the annualization factor (e.g., 252 for daily data).

  • 03

    Can I use this for weekly or monthly data?

    Yes, simply set the annualization factor to 52 for weekly data or 12 for monthly data when calling calculate_volatility_metrics.
