strategy.py

import tradomate as tm

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

    # Trying out Vector Trigonometric Cos
    cos = tm.ta.cos(data.close)

    # Get the last value and print
    last_value = cos.iloc[-1]
    tm.log(f"Last value of Vector Trigonometric Cos is {last_value}")

    # Plot the values of cos
    tm.plot(cos, title="Vector Trigonometric Cos", overlay=False)
