The Obelisk_Ichimoku_Slow_v1_1 strategy is an implementation of the IStrategy class for backtesting trading strategies. Here is a breakdown of what the strategy does:
populate_indicators function:
This function takes a DataFrame and metadata as input parameters. If the timeframe of the strategy is equal to the informative timeframe, it applies indicators to the DataFrame using the do_indicators method.
Otherwise, if there is no informative DataFrame available, it returns the original DataFrame.
If there is an informative DataFrame, it applies indicators to the informative DataFrame using the do_indicators method.
Then, it merges the informative DataFrame into the original DataFrame using the merge_informative_pair function, aligning the timeframes. It renames columns by removing the informative timeframe suffix from column names, except for certain skip columns. Finally, it returns the modified DataFrame. populate_buy_trend function:
This function takes a DataFrame and metadata as input parameters. It checks for a condition where the 'go_long' column in the DataFrame is greater than 0. For rows that satisfy the condition, it sets the 'buy' column to 1. It returns the modified DataFrame. populate_sell_trend function:
This function takes a DataFrame and metadata as input parameters. It checks for a condition where the 'go_long' column in the DataFrame is equal to 0. For rows that satisfy the condition, it sets the 'sell' column to 1. It returns the modified DataFrame. Overall, the strategy involves populating indicators, determining buy signals based on the 'go_long' column, and determining sell signals based on the absence of a buy signal.
