Package mocks is a generated GoMock package.

Return series that having all the elements positive.

Add two series, result[i] = a[i] + b[i].

Array extracts elements from the Series to a float64 array, following the order of Index(0..limit) if limit is given, will only take the first limit numbers (a.Index[0..limit]) otherwise will operate on all elements.

similar to pandas.Series.autocorr() function.

Difference between current value and previous, a - a[offset] offset: if not given, offset is 1.

similar to pandas.Series.corr() function.

CrossEntropy computes the cross-entropy between the two distributions.

a series cross above b series.

a series cross under b series.

Divid two series, result[i] = a[i] / b[i].

Calculate (a dot b).

Entropy computes the Shannon entropy of a distribution or the distance between two distributions.

Filter function filters Series by using a boolean function.

Calculate the average value of the series if limit is given, will only calculate the average of first limit numbers (a.Index[0..limit]) otherwise will operate on all elements.

Multiple two series, result[i] = a[i] * b[i].

This will make prediction using Linear Regression to get the next cross point Return (offset from latest, crossed value, could cross) offset from latest should always be positive lookback param is to use at most `lookback` points to determine linear regression functions You may also refer to excel's FORECAST function.

Determines the Omega ratio of a strategy See https://en.wikipedia.org/wiki/Omega_ratio for more details @param returns (Series): Series of profit/loss percentage every specific interval @param returnThresholds(float64): threshold for returns filtering @return Omega ratio for give return series and threshold.

Percentage change between current and a prior element, a / a[offset] - 1.

Similar to Array but in reverse order.

Sharpe: Calcluates the sharpe ratio of access returns @param returns (Series): Series of profit/loss percentage every specific interval @param periods (int): Freq.

Sigmoid returns the input values in range of -1 to 1 along the sigmoid or s-shaped curve.

similar to pandas.Series.skew() function.

SoftMax returns the input value in the range of 0 to 1 with sum of all the probabilities being equal to one.

Sortino: Calcluates the sotino ratio of access returns ROI_excess E[ROI] - ROI_risk_free sortino = ---------- = ----------------------- risk sqrt(E[ROI_drawdown^2]) @param returns (Series): Series of profit/loss percentage every specific interval @param riskFreeReturns (float): risk-free return rate of year @param periods (int): Freq.

SortOrdersByPrice sorts by creation time ascending-ly.

SortOrdersDescending sorts by creation time descending-ly.

SortOrdersAscending sorts by update time ascending-ly.

Sub two series, result[i] = a[i] - b[i].

Calculate sum of the series if limit is given, will only sum first limit numbers (a.Index[0..limit]) otherwise will sum all elements.

channels for futures.

OrderStatusCanceled means the order is canceled without partially filled or filled.

OrderStatusFilled means the order is fully-filled, it's an end state.

OrderStatusNew means the order is active on the orderbook without any filling.

OrderStatusPartiallyFilled means the order is partially-filled, it's an end state, the order might be canceled in the end.

OrderStatusRejected means the order is not placed successfully, it's rejected by the api.
