Unreliable Script Location Detection 
Tell me more
What is the issue?
Relying on sys.argv[0] for determining the script location is unreliable as it can be manipulated or may not work as expected when the script is run in different contexts (e.g., as a module or via python -m).
Why this matters
This can cause the configuration loading to fail in various execution contexts, leading to runtime errors.

Unsafe Configuration File Execution
Tell me more
What is the issue?
The loaded configuration module's namespace is not isolated, allowing configuration files to execute arbitrary Python code and potentially import harmful modules.
Why this matters
This poses a security risk as malicious configuration files could execute dangerous operations or access sensitive system resources.

Lack of comments for 'ConfigsHelper' and 'load_config' usage. 
Tell me more
Please provide comments for the usage of 'ConfigsHelper' and the 'load_config' being used under 'if name == "main":'. As best practice and to maintain code readability, it's important to document major class or method utilizations.

Missing Weights Validation
Tell me more
What is the issue?
Target weights sum not validated to ensure they equal 1.0 (100%).
Why this matters
Without validation, incorrect weight configurations could be provided, leading to improper portfolio allocation.

Description by Korbit AI
What change is being made?
Introduce a
ConfigsHelperclass responsible for loading strategy parameters from configuration files and update theclassic_60_40strategy to use this new class for parameter management.Why are these changes being made?
These changes promote a more modular and maintainable code structure by separating configuration management from strategy logic, making it easier to reuse and manage configuration data. The added
ConfigsHelperclass provides a systematic approach to loading configuration parameters, facilitating future scalability and flexibility in handling configurations. Additionally, a test case is included to ensure theConfigsHelperworks as expected, reinforcing code reliability.
