strategy.py

import tradomate as tm

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

    # Trying out Rate of change ratio 100 scale: (price/prevPrice)*100
    rocr100 = tm.ta.rocr100(data.close, timeperiod=10)

    # Get the last value and print
    last_value = rocr100.iloc[-1]
    tm.log(f"Last value of Rate of change ratio 100 scale: (price/prevPrice)*100 is {last_value}")

    # Plot the values of rocr100
    tm.plot(rocr100, title="Rate of change ratio 100 scale: (price/prevPrice)*100", overlay=False)
