macd_line(X, fast_w=12, slow_w=26, kind='e', axis=0, dtype=None)[source]

Compute Moving Average Convergence Divergence Line.

MACD is a trading indicator used in technical analysis of stock prices, created by Gerald Appel in the late 1970s [4]. It is designed to reveal changes in the strength, direction, momentum, and duration of a trend in a stock’s price.

Parameters:
Xnp.ndarray[dtype, ndim=1 or 2]

Elements to compute the indicator. If X is a two-dimensional array, then an indicator is computed for each series along axis.

fast_wint, optional

Size of the lagged window of the short moving average, must be strictly positive. Default is 12.

slow_wint, optional

Size of the lagged window of the lond moving average, must be strictly positive. Default is 26.

kind{‘e’, ‘s’, ‘w’}

  • If ‘e’ (default) then use exponential moving average, see ema for details.

  • If ‘s’ then use simple moving average, see sma for details.

  • If ‘w’ then use weighted moving average, see wma for details.

axis{0, 1}, optional

Axis along wich the computation is done. Default is 0.

dtypenp.dtype, optional

The type of the output array. If dtype is not given, infer the data type from X input.

Returns:
np.ndarray[dtype, ndim=1 or 2]

Moving average convergence/divergence line of each series.
