    This is a test hyperopt to inspire you.

    More information in https://github.com/freqtrade/freqtrade/blob/develop/docs/hyperopt.md

    You can:
    - Rename the class name.
    - Add any methods you want to build your hyperopt.
    - Add any lib you need to build your hyperopt.

    You must keep:
    - The prototypes for the methods: populate_indicators, indicator_space, buy_strategy_generator.

    The roi_space, generate_roi_table, stoploss_space methods were moved to the parent class, you may
    override them here if you need it.
