Session Goal

The session aimed to troubleshoot and resolve data loading issues in the Backtrader framework, specifically related to the ResidualsCSVData class.

Key Activities

• Identified and addressed a problem with the ResidualsCSVData class where data lengths were reported as zero despite accessible data.
• Debugged the data feed length issue by revising the strategy to ensure correct data handling.
• Modified the ResidualsCSVData class to read entire CSV files for time series data extraction.
• Fixed a TypeError during the initialization of the ResidualsCSVData class by revising the code to correctly initialize the parent class with appropriate parameters.
• Addressed a None parameter error in the PandasData class by ensuring a Pandas DataFrame is correctly passed to the superclass.

Achievements

• Successfully resolved data loading and initialization errors in the ResidualsCSVData and PandasData classes in Backtrader.
• Improved the data handling strategy for CSV files, enabling proper time series data extraction.

Pending Tasks

• Further testing of the revised classes and strategies in different scenarios to ensure robustness and reliability.
