The DefaultStrategy is a trading strategy that uses technical analysis (TA) indicators to generate buy and sell signals. In the populate_indicators method, the strategy calculates various TA indicators such as ADX (Average Directional Index), MACD (Moving Average Convergence Divergence), MINUS_DI, PLUS_DI, RSI (Relative Strength Index), STOCHF (Stochastic Fast), Bollinger Bands, EMA (Exponential Moving Average), and SMA (Simple Moving Average). These indicators are added as additional columns to the input DataFrame.
The populate_buy_trend method populates the "buy" column in the DataFrame based on specific conditions.
It generates a buy signal when the RSI is below 35, the fastd (Stochastic Fast) is below 35, the ADX is above 30, and the plus_di (PLUS_DI) is above 0.5.
Alternatively, a buy signal is generated when the ADX is above 65 and the plus_di is above 0.5. The populate_sell_trend method populates the "sell" column in the DataFrame based on certain conditions. It generates a sell signal when either the RSI or fastd crosses above 70, the ADX is above 10, and the minus_di (MINUS_DI) is above 0. Alternatively, a sell signal is generated when the ADX is above 70 and the minus_di is above 0.5. Overall, the DefaultStrategy calculates TA indicators and uses them to determine buy and sell signals based on specific conditions.
