Functions ¶
func CrossOver ¶
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.
ported from https://github.com/markcheno/go-talib/blob/master/talib.go
func CrossUnder ¶
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.
ported from https://github.com/markcheno/go-talib/blob/master/talib.go
func MinMax ¶
MinMax - Lowest and highest values over a specified period ported from https://github.com/markcheno/go-talib/blob/master/talib.go
func Percentile ¶ added in v1.63.0
Percentile function calculates the p-th percentile of a slice of float64 numbers. Use linear interpolation to find the percentile value.
Types ¶
type Slice ¶

func (Slice) Index ¶
Index fetches the element from the end of the slice WARNING: it does not start from 0!!!
