Functions ¶
func ArithmeticMean ¶
ArithmeticMean is the basic form of calculating an average. Divide the sum of all values by the length of values
func CalculateAmountWithFee ¶
CalculateAmountWithFee returns a calculated fee included amount on fee
func CalculateFee ¶
CalculateFee returns a simple fee on amount
func CalculateNetProfit ¶
CalculateNetProfit returns net profit
func CalculatePercentageDifference ¶
CalculatePercentageDifference returns the percentage of difference between multiple time periods
func CalculatePercentageGainOrLoss ¶
CalculatePercentageGainOrLoss returns the percentage rise over a certain period
func CalmarRatio ¶
func CalmarRatio(highestPrice, lowestPrice, average, riskFreeRateForPeriod float64) (float64, error)
CalmarRatio is a function of the average compounded annual rate of return versus its maximum drawdown. The higher the Calmar ratio, the better it performed on a risk-adjusted basis during the given time frame, which is mostly commonly set at 36 months
func CompoundAnnualGrowthRate ¶
func CompoundAnnualGrowthRate(openValue, closeValue, intervalsPerYear, numberOfIntervals float64) (float64, error)
CompoundAnnualGrowthRate Calculates CAGR. Using years, intervals per year would be 1 and number of intervals would be the number of years Using days, intervals per year would be 365 and number of intervals would be the number of days
func FinancialGeometricMean ¶
FinancialGeometricMean is a modified geometric average to assess the negative returns of investments. It accepts It adds +1 to each This does impact the final figures as it is modifying values It is still ultimately calculating a geometric average which should only be compared to other financial geometric averages
func GeometricMean ¶
GeometricMean is an average which indicates the central tendency or typical value of a set of numbers by using the product of their values The geometric average can only process positive numbers
func InformationRatio ¶
func InformationRatio(returnsRates, benchmarkRates []float64, averageValues, averageComparison float64) (float64, error)
InformationRatio The information ratio (IR) is a measurement of portfolio returns beyond the returns of a benchmark, usually an index, compared to the volatility of those returns. The benchmark used is typically an index that represents the market or a particular sector or industry.
func PopulationStandardDeviation ¶
PopulationStandardDeviation calculates standard deviation using population based calculation
func RoundFloat ¶
RoundFloat rounds your floating point number to the desired decimal place
func SampleStandardDeviation ¶
SampleStandardDeviation standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance
