Troubleshooting Non-String Strategy Parameters in Backtesting

Summary

This short forum exchange reports a TypeError encountered when opening a backtesting module. The response attributes it to a strategy parameter-name list containing an item that is not a string, which prevents the framework from using that item as an attribute name.

The page contains no strategy, backtest results, diagnostic procedure, or supporting example. Its limited practical lesson is to check that every parameter name supplied to the framework is a string; the exchange does not establish whether that explanation covers other causes of the error.

Key ideas

• A strategy parameter-name list containing a non-string entry may trigger a TypeError in the backtesting module.
• The forum response provides a diagnosis but no reproduction steps or correction example.
• The note concerns framework configuration rather than trading research or strategy design.
