📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal:

The session aimed to troubleshoot and resolve data feed issues in Backtrader strategies, specifically focusing on the Cerebro framework and the ResidualsCSVData class.

Key Activities:

• Troubleshooting Data Access: Explored methods to resolve data access issues within a Cerebro strategy, focusing on correct data referencing and indexing.
• Minimal Backtrader Strategy: Developed a minimal strategy to test and debug residual data loading and access.
• Expanded Diagnostics: Implemented detailed diagnostics in the TestResidualsStrategy class to identify data feed issues.
• Debugging Techniques: Applied systematic approaches to debug data reading issues, including checking data integrity and modifying CSV readers.
• Understanding ResidualsCSVData: Clarified the structure and usage of the ResidualsCSVData class, focusing on its integration with financial data analysis.
• Zero-Length Data Feeds: Investigated and addressed zero-length data feed issues, focusing on CSV content and data loading methods.

Achievements:

• Successfully identified and resolved several data feed issues in Backtrader strategies, enhancing data accessibility and integrity.
• Improved understanding of the ResidualsCSVData class and its application in financial data analysis.

Pending Tasks:

• Further testing of modified strategies to ensure robustness across different datasets.
• Continued refinement of debugging techniques for complex data feed scenarios.
