    Convolutional LSTM mixed Neural Network and technical indicator strategy.
    Inspired by the research of Saul et al. More information can be found on
    https://www.sciencedirect.com/science/article/abs/pii/S0957417420300750

    This strategy will utilise the following technical indicators as features:
      - Accumulation/Distribution Oscillator (A/D)
      - Commodity Channel Index (CCI)
      - Larry William's R (LWI)
      - Momentum
      - Moving average convergence divergence (MACD)
      - Relative Strength Index (RSI)
      - SMA5, SMA10, SMA20, SMA30, SMA60
      - Stochastic D%
      - Stochastic K%
      - Weighted moving average 5, 10, 20, 30, 60


    You can:
        :return: a Dataframe with all mandatory indicators for the strategies
    - Rename the class name (Do not forget to update class_name)
    - Add any methods you want to build your strategy
    - Add any lib you need to build your strategy

    You must keep:
    - the lib in the section "Do not remove these libs"
    - the methods: populate_indicators, populate_entry_trend, populate_exit_trend
    You should keep:
    - timeframe, minimal_roi, stoploss, trailing_*
