The HyperoptableStrategy class is a trading strategy implementation that utilizes various technical analysis (TA) indicators to make buy and sell decisions. The populate_indicators method adds several TA indicators to the given DataFrame. These indicators include ADX (Average Directional Index), MACD (Moving Average Convergence Divergence), MINUS_DI, PLUS_DI, RSI (Relative Strength Index), Stochastic Fast, Bollinger Bands, and EMA (Exponential Moving Average).
The method calculates the values of these indicators and adds them as new columns to the DataFrame.
The populate_buy_trend method populates the buy signal for the DataFrame based on the values of the TA indicators.
It sets the 'buy' column of the DataFrame to 1 for rows that satisfy the specified buy conditions. These conditions include a low RSI value, a low Stochastic Fast value, a high ADX value, and a high PLUS_DI value. The populate_sell_trend method populates the sell signal for the DataFrame based on the values of the TA indicators. It sets the 'sell' column of the DataFrame to 1 for rows that satisfy the specified sell conditions. These conditions include crossing above a specified RSI value or Stochastic Fast value, a high ADX value, and a high MINUS_DI value. Overall, the HyperoptableStrategy class uses TA indicators to generate buy and sell signals for trading based on predefined conditions.
