"""
Auto-trade kill switch.

Usage:
    python kalshi_kill.py on      -> create kill-switch file (auto-trade disabled)
    python kalshi_kill.py off     -> remove kill-switch file (auto-trade allowed)
    python kalshi_kill.py status  -> show current state

When the file E:/soccer/AUTO_TRADE_KILL exists, place_auto_order() in
daily_signals.py refuses to place ANY orders, even if AUTO_TRADE_ENABLED=True.
This is the panic button.
