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)
