MovingAverages
Library "MovingAverages"
Contains utilities for generating moving average values including getting a moving average by name and a function for generating a Volume-Adjusted WMA.
vawma(len, src, volumeDefault) VAWMA = VWMA and WMA combined. Simply put, this attempts to determine the average price per share over time weighted heavier for recent values. Uses a triangular algorithm to taper off values in the past (same as WMA does).
Parameters:
getMA(mode, len, src) Generates a moving average based upon a 'mode'.
Parameters:
Contains utilities for generating moving average values including getting a moving average by name and a function for generating a Volume-Adjusted WMA.
vawma(len, src, volumeDefault) VAWMA = VWMA and WMA combined. Simply put, this attempts to determine the average price per share over time weighted heavier for recent values. Uses a triangular algorithm to taper off values in the past (same as WMA does).
Parameters:
- len: The number of bars to measure with.
- src: The series to measure from. Default is 'hlc3'.
- volumeDefault: The default value to use when a chart has no (N/A) volume.
getMA(mode, len, src) Generates a moving average based upon a 'mode'.
Parameters:
- mode: The type of moving average to generate. Values allowed are: SMA, EMA, WMA, VWMA and VAWMA.
- len: The number of bars to measure with.
- src: The series to measure from. Default is 'close'.

v4 Added CMA
Added:
cma(n, D, C, compound) CMA is a variation of a moving average that can simulate SMA or WMA with the advantage of previous data. ifta.org/wp-content/..._ifta_journal_21.pdf
Parameters:
n: The number of bars to measure with.
D: The series to measure from. Default is 'close'.
C: The coefficient to use when averaging. 0 behaves like SMA, 1 behaves like WMA.
compound: When true (default is false) will use a compounding method for weighting the average.

v11
Added:
rsvwma(transferRatio, releaseRatio, useTime, src, vol)
This is experimental moving average doesn't use a period/length but instead buffers the price per share and transfers that price per share at a given ratio per bar while also releasing the previous values at a decay ratio.
Parameters:
transferRatio: The ratio at which buffered data is applied to the average.
releaseRatio: The ratio at which data is released from the average.
useTime: When true will tend to make the values consistent across timeframes.
src: The series to measure from. Default is 'hlc3'.
vol: The series to represent volume. The default is 'volume'.
