Run a self-healing crypto trading bot 24/7 for $0 (Freqtrade + watchdog)

Maintaining a Freqtrade trading bot 24/7 requires more than a successful backtest. Many users face process failures shortly after startup, leading to lost trading opportunities. To solve this, a production-shaped, zero-cost setup using open-source tooling is essential. Operators typically choose between systemd and a cron watchdog to ensure the bot restarts automatically. This self-healing approach allows for continuous operation, automated P L logging, and defined risk hard-stops without requiring a financial budget.
