Days "Higher" and "Lower"

Another statistic used alongside formations and other theories is the day higher and lower calculation. This calculation determines how many days, in a defined set of price bars, were "higher" or "lower." A day is considered a "Higher Day" if the close is higher than any previous close in the set of price bars selected. Conversely, a day is considered a "Lower Day" if the close is lower than any previous trading day in the defined set of price bars.
