The bb_rsi_opt_new strategy is a backtesting strategy that combines Bollinger Bands and Relative Strength Index (RSI) indicators to generate buy signals for trading. Here's a breakdown of what the strategy does:
populate_indicators function:
Calculates the RSI (Relative Strength Index) indicator using the input dataframe. Calculates two sets of Bollinger Bands using the typical price of the dataframe.
Adds the RSI values and Bollinger Bands values to the dataframe as new columns.
populate_buy_trend function:
Determines the buy signal based on certain conditions:
RSI value is greater than 28.
The closing price is below the lower Bollinger Band (4 standard deviations). Sets the 'buy' column to 1 for the rows that meet the buy conditions. populate_sell_trend function:
Sets the 'sell' column to 0 for all rows, indicating no sell signal. Overall, the strategy aims to identify buying opportunities when the RSI is high and the price is below the lower Bollinger Band (4 standard deviations). It does not provide specific sell signals, indicating that the strategy does not recommend any specific time or condition to sell.
