    Available MAs: dema, ema, fwma, hma, linreg, midpoint, pwma, rma,
    sinwma, sma, ssf, swma, t3, tema, trima, vidya, wma.

    Parameters:
        name (str): One of the Available MAs. Default: "ema"
        source (Series): Input Series ```source```.

    Other Parameters:
        kwargs (**kwargs): Additional args for the MA.
