trader.config.settings module

Raw configuration sourcing from .env.

This module only reads values. Deciding whether those values are safe to act on is loader.py’s job — keeping the two separate means a later change to where config lives does not touch the safety gate.

class trader.config.settings.LogLevel(*values)[source]

Bases: StrEnum

Verbosity for the rotating log file.

A closed set rather than a free string: LOG_LEVEL=VERBOSE should fail at load with the valid values named, not fall back to INFO and leave someone hunting for why their debug output never appeared.

DEBUG = 'DEBUG'
INFO = 'INFO'
WARNING = 'WARNING'
ERROR = 'ERROR'
CRITICAL = 'CRITICAL'
