    idea:

        uptrend definition:
            MACD above MACD signal
            and CCI < -50

        downtrend definition:
            MACD below MACD signal
            and CCI > 100

    freqtrade hyperopt --strategy MACDStrategy --hyperopt-loss <someLossFunction> --spaces buy sell

    The idea is to optimize only the CCI value.
    - Buy side: CCI between -700 and 0
    - Sell side: CCI between 0 and 700
