help(ta.ema)

Help on function ema in module pandas_ta.overlap.ema:

ema(close, length=None, offset=None, **kwargs)
    Exponential Moving Average (EMA)
    
    The Exponential Moving Average is more responsive moving average compared to the
    Simple Moving Average (SMA).  The weights are determined by alpha which is
    proportional to it's length.  There are several different methods of calculating
    EMA.  One method uses just the standard definition of EMA and another uses the
    SMA to generate the initial value for the rest of the calculation.
    
    Sources:
        https://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:moving_averages
        https://www.investopedia.com/ask/answers/122314/what-exponential-moving-average-ema-formula-and-how-ema-calculated.asp
    
    Calculation:
        Default Inputs:
            length=10, adjust=False, sma=True
        if sma:
            sma_nth = close[0:length].sum() / length
            close[:length - 1] = np.NaN
            close.iloc[length - 1] = sma_nth
        EMA = close.ewm(span=length, adjust=adjust).mean()
    
    Args:
        close (pd.Series): Series of 'close's
        length (int): It's period.  Default: 10
        offset (int): How many periods to offset the result.  Default: 0
    
    Kwargs:
        adjust (bool, optional): Default: False
        sma (bool, optional): If True, uses SMA for initial value. Default: True
        fillna (value, optional): pd.DataFrame.fillna(value)
        fill_method (value, optional): Type of fill method
    
    Returns:
        pd.Series: New feature generated.

Indicator Examples

• Examples of simple and complex indicators. Most indicators return a Series, while a few return DataFrames.
• All indicators can be called one of three ways. Either way, they return the result.

Three ways to use pandas_ta

1. Stand Alone like TA-Lib ta.indicator(kwargs).
2. As a DataFrame Extension like df.ta.indicator(kwargs). Where df is a DataFrame with columns named "open", "high", "low", "close, "volume" for simplicity.
3. Similar to #2, but by calling: df.ta(kind="indicator", kwargs).

Cumulative Log Return

In [12]:

clr_ma_length = 8
clrdf = df.ta.log_return(cumulative=True, append=True)
clrmadf = ta.ema(clrdf, length=clr_ma_length)
qqdf = pd.DataFrame({f"{clrdf.name}": clrdf, f"{clrmadf.name}({clrdf.name})": clrmadf})
qqdf.tail(recent).plot(figsize=ind_size, color=colors("BkBl"), linewidth=1, title=ctitle(clrdf.name, ticker=ticker, length=recent), grid=True)

macddf[[macddf.columns[0], macddf.columns[2]]].tail(recent).plot(figsize=(16, 2), color=colors("BkBl"), linewidth=1.3)

Archer Moving Average Trends (amat) returns the long and short run trends of fast and slow moving averages.

• The pink background, on the Price chart, is when Archer MAs are bearish. Conversely, a white background is bullish
