As far as the intraday data goes, this depends on the time period. For instance,
using 15 minute bars, one year is going to be equivalent to 4 years of daily
data. However, if you're using, say, 2 min. bars, you're going to get 30 years
worth, which seems to be a reasonable sample. If you were using 1 min. bars,
like some traders do, you'd get 60 years worth out of this.
