Functions ¶

func Average ¶

func Average(arr []float64) float64

func CalculatePivot ¶

func CalculatePivot(values Slice, left, right int, f func(a, pivot float64) bool) (float64, bool)

func CrossOver ¶

func CrossOver(series1 []float64, series2 []float64) bool

CrossOver returns true if series1 is crossing over series2.

NOTE: Usually this is used with Media Average Series to check if it crosses for buy signals.
      It assumes first values are the most recent.
      The crossover function does not use most recent value, since usually it's not a complete candle.
      The second recent values and the previous are used, instead.

func CrossUnder ¶

func CrossUnder(series1 []float64, series2 []float64) bool

CrossUnder returns true if series1 is crossing under series2.

NOTE: Usually this is used with Media Average Series to check if it crosses for sell signals.
