alphaConfigurableEma(src, alpha, nSmooth)
Calculates a variation of the EMA by specifying a custom alpha value.
Parameters:
src (float): a float series to get the EMA for, e.g. close, hlc3, etc.
alpha (float): a value between 0 (ideally greater, to get any MA!) and 1. Closer
to one makes it more responsive, and choppier.
nSmooth (int): Just applies the same alpha and EMA to the last Alpha-EMA output.
A value between 0 and 10 (just keeping a a reasonable bound). The idea is
you can first use a reasonably high alpha, then smooth it out. Default 0,
no further smoothing.
Returns: MA series.
bands(src, multiplier)
Calculates fixed bands around a series, can be any series, though the intent
here is for MA series.
Parameters:
src (float): a float series.
multiplier (float): a value greater than or equal to 0 (ideally greater, to get any MA!),
determines the width of the bands. Start with small float values, or it may go
beyond the scale, e.g. 0.005.
Returns: a 2-tuple of (upBand, downBand)

dema(src, len)
Calculates the Double Exponential Moving Average (DEMA)
Parameters:
src (float): a float series to get the DEMA for, e.g. close, hlc3, etc.

Parameters:
src (float): a float series to get the TEMA for, e.g. close, hlc3, etc.
