Output	Type
apo	np.ndarray

Example usage

strategy.py

import tradomate as tm

@tm.strategy()
def my_strategy(config: tm.TradomateConfig, data: tm.TradomateData):

    # Trying out Absolute Price Oscillator
    apo = tm.ta.apo(data.close, fastperiod=12, slowperiod=26, matype=0)

    # Get the last value and print
    last_value = apo.iloc[-1]
    tm.log(f"Last value of Absolute Price Oscillator is {last_value}")

    # Plot the values of apo
    tm.plot(apo, title="Absolute Price Oscillator", overlay=False)
