🏷️ Labels: Backtrader, Data Loading, Python, Error Handling, Pandas
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal:

The primary goal of this session was to troubleshoot and resolve data loading issues in the Backtrader framework, specifically focusing on the ResidualsCSVData class.

Key Activities:

  • Troubleshooting Data Loading: Identified issues with the ResidualsCSVData class where data lengths were reported as zero. Verified the CSV format to ensure correct data loading.
  • Debugging Data Feed Length: Revised strategies to directly access data points in Backtrader, ensuring accurate data handling.
  • Modifying Class for Time Series: Modified the ResidualsCSVData class to read entire CSV files for multiple tickers, enabling time series data extraction.
  • Fixing Initialization Errors: Addressed TypeErrors during the initialization of the ResidualsCSVData class by correctly initializing the parent class with appropriate parameters.
  • Correcting Data Parameter Errors: Solved issues with the dataname parameter being None by ensuring a Pandas DataFrame is correctly passed to the PandasData class.

Achievements:

  • Successfully resolved data loading and initialization errors in the ResidualsCSVData and PandasData classes.
  • Improved the data handling strategy in Backtrader, allowing for more robust time series data processing.

Pending Tasks:

  • Further testing is required to validate the changes across different datasets and scenarios in Backtrader to ensure robustness.
