The BigZ03 strategy is a trading strategy implemented as a class that inherits from the IStrategy interface. It consists of several methods that define its behavior. The populate_indicators method is responsible for calculating and adding various indicators to the input dataframe.
It calls the informative_1h_indicators method to calculate indicators based on 1-hour data and merges the results into the main dataframe.
Then, it applies additional indicators using the normal_tf_indicators method and returns the modified dataframe.
The populate_buy_trend method determines the buying conditions for the strategy. It checks various conditions using logical operators and column comparisons within the dataframe. The conditions involve comparisons with moving averages (ema_200, ema_200_1h), Bollinger Bands (bb_lowerband, bb_middleband, bb_upperband), relative strength index (rsi, rsi_1h), volume, open, close, and other variables. If any of the conditions are met, a buying signal is generated for the corresponding data point in the dataframe. Overall, the BigZ03 strategy aims to identify potential buying opportunities based on specific technical indicators and conditions in the market. It uses a combination of moving averages, Bollinger Bands, volume analysis, and other criteria to determine when to enter a trade.
