The DefaultStrategy class is a trading strategy that implements various technical analysis (TA) indicators to generate buy and sell signals. Here is a brief description of what the strategy does:
populate_indicators: This method adds multiple TA indicators to the given DataFrame. The indicators include ADX (Average Directional Index), AO (Awesome Oscillator), MACD (Moving Average Convergence Divergence), MFI (Money Flow Index), RSI (Relative Strength Index), Fisher RSI, Stochastic Oscillator (slowd and slowk), Bollinger Bands, Exponential Moving Averages (ema3, ema5, ema10, ema50, ema100), SAR (Stop and Reverse), SMA (Simple Moving Average), TEMA (Triple Exponential Moving Average), Hilbert Transform - Sine Wave (htsine and htleadsine), and Heikin-Ashi candles.
populate_buy_trend: This method populates the buy signal based on the TA indicators.
The buy conditions include low RSI (<35), low Stochastic Oscillator (fastd < 35), high ADX (>30), and positive Plus Directional Indicator (plus_di > 0.5).
Additionally, if ADX is very high (>65) and the Plus Directional Indicator is positive, a buy signal is generated. populate_sell_trend: This method populates the sell signal based on the TA indicators. The sell conditions include crossing above the overbought threshold for RSI or Stochastic Oscillator, ADX being above a certain threshold (>10), and the Minus Directional Indicator (minus_di) being positive. Additionally, if ADX is very high (>70) and the Minus Directional Indicator is positive, a sell signal is generated. Overall, the strategy aims to identify potential buying opportunities when certain indicators suggest oversold conditions and selling opportunities when indicators suggest overbought conditions or strong downtrends.
