The BBL3H1Strategy is a trading strategy that uses technical indicators to generate buy and sell signals. Here's a breakdown of what the strategy does:
populate_indicators function:
This function adds several technical analysis (TA) indicators to the given DataFrame. The indicators added are Bollinger Bands with a window of 20 and standard deviation of 3 (bb_lowerband3) and Bollinger Bands with a window of 20 and standard deviation of 1 (bb_upperband1).
populate_buy_trend function:
Based on the TA indicators, this function populates the buy signal for the DataFrame.
The buy signal is generated when the closing price is below the bb_lowerband3.
populate_sell_trend function:
Based on the TA indicators, this function populates the sell signal for the DataFrame. The sell signal is generated when the closing price is above the bb_upperband1. The strategy calculates Bollinger Bands to identify potential buying and selling opportunities based on price deviations from the bands. When the closing price falls below the lower Bollinger Band (bb_lowerband3), a buy signal is generated. Conversely, when the closing price rises above the upper Bollinger Band (bb_upperband1), a sell signal is generated. These functions are part of the BBL3H1Strategy class, which implements the IStrategy interface.
