The DefaultStrategy class is an implementation of a trading strategy for backtesting purposes. It extends the IStrategy class and provides methods to populate indicators, generate buy signals, and generate sell signals for a given DataFrame of trading data. The populate_indicators method adds various technical analysis (TA) indicators to the DataFrame.
These indicators include ADX, Awesome Oscillator, MACD, MFI, Minus DM, Minus DI, Plus DM, Plus DI, RSI, Fisher RSI, Stochastic Oscillator, Bollinger Bands, Exponential Moving Averages (EMA), SAR, Simple Moving Average (SMA), Triple Exponential Moving Average (TEMA), Hilbert Transform - Sine Wave, and Heikin-Ashi candles.
The populate_buy_trend method generates buy signals based on the values of the TA indicators in the DataFrame.
The buy conditions include low RSI, low fast %D of Stochastic Oscillator, high ADX, and positive Plus DI. The populate_sell_trend method generates sell signals based on the values of the TA indicators in the DataFrame. The sell conditions include crossing above 70 for RSI or fast %D, ADX above 10, and positive Minus DI. By using this DefaultStrategy class, you can backtest different trading strategies by evaluating the performance of the buy and sell signals generated by the TA indicators on historical trading data.
