The NostalgiaForInfinityNextGen strategy is designed to backtest trading strategies. Here's a brief description of what the strategy does:
populate_indicators: This method populates the indicators needed for the strategy. It retrieves BTC (Bitcoin) data and merges it with the input dataframe, creating informative timeframes and resampling if specified.
It also calculates various indicators such as moving averages (EMA and SMA) and percentage changes.
The method returns the updated dataframe.
populate_buy_trend: This method populates the buy trend for the strategy. It defines conditions based on the strategy's buy protection parameters. The conditions include checks on indicators such as EMAs, SMAs, and percentage changes. If the conditions are met, a buy tag is assigned to the corresponding rows in the dataframe. These methods are part of the NostalgiaForInfinityNextGen class, which implements the IStrategy interface. Please note that the provided code snippet is incomplete, and some parts are cut off. The description is based on the available code, but there may be additional functionality or details not covered.
