Session Goal

The goal of this session was to troubleshoot and resolve issues related to displaying and saving plots in Python, specifically using Matplotlib within the Backtrader framework.

Key Activities

  • Troubleshooting Plot Display: Addressed issues with plot display in interactive Python environments, including configuration checks and explicit plot saving.
  • Handling Unexpected Outputs: Modified code to handle unexpected outputs from cerebro.plot(), ensuring proper saving of figures.
  • Code Refinement: Updated Python code to save Matplotlib figures from a nested list structure with unique filenames.
  • Resolving Time Series Issues: Focused on plotting OLSResiduals indicator only once and identified missing cash and total investment line plots.
  • Configuring Data Feeds: Managed multiple data feed instances in Backtrader, focusing on plotting cash and total investment.
  • Customizing Plotting: Customized plotting for Broker and Trades observers in the Cerebro framework.

Achievements

  • Successfully resolved plotting issues in Matplotlib within the Backtrader context.
  • Enhanced code to correctly save figures with unique filenames.
  • Improved configuration for data feeds and plotting observers in Backtrader.

Pending Tasks

  • Further testing of the refined code in various interactive environments to ensure robustness.
