Example usage

strategy.py

import tradomate as tm

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

    # Trying out Vector Arithmetic Subtraction
    sub = tm.ta.sub(data.high, data.low)

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

    # Plot the values of sub
    tm.plot(sub, title="Vector Arithmetic Subtraction", overlay=False)
