ArrayMovingAverages

Library "ArrayMovingAverages"

This library adds several moving average methods to arrays, so you can call, eg.:

myArray.ema(3)

method emaArray(id, length)
Calculate Exponential Moving Average (EMA) for Arrays
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
length (int): (int) Length of the EMA
Returns: (array<float>) Array of EMA values

method ema(id, length)
Get the last value of the EMA array
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
length (int): (int) Length of the EMA
Returns: (float) Last EMA value or na if empty

method rmaArray(id, length)
Calculate Rolling Moving Average (RMA) for Arrays
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
length (int): (int) Length of the RMA
Returns: (array<float>) Array of RMA values

method rma(id, length)
Get the last value of the RMA array
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
length (int): (int) Length of the RMA
Returns: (float) Last RMA value or na if empty

method smaArray(id, windowSize)
Calculate Simple Moving Average (SMA) for Arrays
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
windowSize (int): (int) Window size for calculation, defaults to array size
Returns: (array<float>) Array of SMA values

method sma(id, windowSize)
Get the last value of the SMA array
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
windowSize (int): (int) Window size for calculation, defaults to array size
Returns: (float) Last SMA value or na if empty

method wmaArray(id, windowSize)
Calculate Weighted Moving Average (WMA) for Arrays
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
windowSize (int): (int) Window size for calculation, defaults to array size
Returns: (array<float>) Array of WMA values

method wma(id, windowSize)
Get the last value of the WMA array
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
windowSize (int): (int) Window size for calculation, defaults to array size
Returns: (float) Last WMA value or na if empty

Release Notes

v2

Added Hull Moving Average.

Added:
method hmaArray(id, length)
Calculate Hull Moving Average (HMA) for Arrays
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
length (int): (int) Length of the HMA
Returns: (array<float>) Array of HMA values

method hma(id, length)
Get the last value of the HMA array
Namespace types: array<float>
Parameters:
id (array<float>): (array<float>) Input array
length (int): (int) Length of the HMA
Returns: (float) Last HMA value or na if empty

Release Notes

v3

Lots of performance updates. Please note hma is still quite slow, I'm still investigating ways to improve it.
