Using Historical Volatility Intraday

[Clint Chastain <flag@xxxxxxxxxxxx>]

The Code I have for Historical Volatility includes a parameter for
annualization of the function. In the examples I can recall having seen, the
indicator was always applied to daily charts and the annualization factor
was variously set to 254, 260, or 365.

Question: is it necessary to modify the code or enter some huge annualizing
factor like 20280 in order to properly apply it to, say, a 5 min intraday
chart?
