The SampleStrategy is a trading strategy that uses various technical analysis (TA) indicators to make buy and sell decisions. The strategy first populates the given DataFrame with several TA indicators, including RSI (Relative Strength Index), ADX (Average Directional Index), MACD (Moving Average Convergence Divergence), MFI (Money Flow Index), Stochastic Fast, Bollinger Bands, SAR (Stop and Reverse), TEMA (Triple Exponential Moving Average), and HT Sine. The populate_buy_trend function uses these indicators to determine the buy signal.
It checks if the RSI crosses above 30, the TEMA is below the Bollinger Bands' middle band, the TEMA is rising, and the volume is not zero.
If all conditions are met, the 'buy' column in the DataFrame is set to 1.
Similarly, the populate_sell_trend function determines the sell signal. It checks if the RSI crosses above 70, the TEMA is above the Bollinger Bands' middle band, the TEMA is falling, and the volume is not zero. If all conditions are met, the 'sell' column in the DataFrame is set to 1. Overall, the strategy uses these indicators to identify potential buying and selling opportunities based on market trends and conditions.
