Library "MovingAverages"

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.
  Returns: The volume adjusted triangular weighted moving average of the series.

cma(n, D, C, compound)
  Coefficient Moving Avereage (CMA) is a variation of a moving average that can simulate SMA or WMA with the advantage of previous data.
  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.

ema(len, src)
  Same as ta.ema(src,len) but properly ignores NA values.
  Parameters:
    len: The number of samples to derive the average from.
    src: The series to measure from. Default is 'close'.

wma(len, src, startingWeight)
  Same as ta.wma(src,len) but properly ignores NA values.
  Parameters:
    len: The number of samples to derive the average from.
    src: The series to measure from. Default is 'close'.
    startingWeight: The weight to begin with when calculating the average. Higher numbers will decrease the bias.

vwma(len, src, volumeDefault)
  Same as ta.vwma(src,len) but properly ignores NA values.
  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.

get(type, len, src)
  Generates a moving average based upon a 'type'.
  Parameters:
    type: 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'.
  Returns: The moving average series requested.
