The strategy, named "CombinedBinHAndCluc2021Bull," is a trading strategy that combines three different sub-strategies: BinHV45, ClucMay72018, and BBRSI. In the first sub-strategy (BinHV45), the strategy uses Bollinger Bands to identify potential buying opportunities. It looks for conditions such as the lower band being greater than zero, the difference between the middle band and the lower band being greater than a certain percentage of the closing price, the difference between consecutive closing prices being greater than a certain percentage of the current closing price, and the distance between the closing price and the lowest price of the candle being smaller than a certain percentage of the difference between the middle band and the lower band.
In the second sub-strategy (ClucMay72018), the strategy looks for buying opportunities based on the price being below the 100-day exponential moving average (EMA), the price being below a certain percentage (0.985) of the lower Bollinger Band, and the volume being lower than the previous average volume multiplied by 20.
In the third sub-strategy (BBRSI), the strategy looks for buying opportunities based on the relative strength index (RSI) being below 12 and the price being below the lower Bollinger Band (standard deviation of 4).
Once a buying opportunity is identified in any of the sub-strategies, a buy signal is generated. The strategy also includes a sell signal based on the price crossing above the middle Bollinger Band. The strategy has predefined values for parameters such as "minimal_roi" (a dictionary defining the minimum return on investment at different time intervals), "stoploss" (a percentage value for the maximum acceptable loss), and "timeframe" (the timeframe for candlestick data used in the strategy). Overall, the strategy combines multiple technical indicators and conditions to generate buy and sell signals, aiming to capture profitable trading opportunities.
