The NFI47 strategy is a trading strategy implemented as a class that inherits from the IStrategy class. It consists of several methods that perform different tasks. The populate_indicators method takes a DataFrame and a metadata dictionary as inputs and returns a DataFrame.
It populates the indicators used in the strategy by calling the informative_1h_indicators method and merging the resulting indicators with the original DataFrame using the merge_informative_pair function.
Then, it applies additional indicators using the normal_tf_indicators method and returns the updated DataFrame.
The populate_buy_trend method also takes a DataFrame and a metadata dictionary as inputs and returns a DataFrame. It defines a list of conditions that determine when to initiate a buy order. Each condition is represented as a logical expression involving various indicators and parameters. If a condition evaluates to True, it signifies that the corresponding buy order should be executed. The method appends all the conditions to a list and returns the DataFrame. Overall, the NFI47 strategy involves calculating indicators, merging them with the original DataFrame, and defining conditions for initiating buy orders based on specific criteria.
