We deploy code updates to a 24/7 revenue-generating trading bot without stopping it. Here's the architectural decision that made that possible — and why the obvious solution was wrong.
Stopping a live trading bot to deploy code is not a deployment strategy — it's a risk management failure. Here's how I solved it.
Most deployment strategies assume you can afford to restart. A live trading bot with open positions cannot. Here's the architecture that changed how we ship.
A $50-bet live trading bot silently hung for 7 hours while generating STRONG signals. No alerts. No restarts. I diagnosed the asyncio event loop failure, killed the process manually, and then built Horus — a self-healing watchdog daemon that would have caught it in under 10 minutes.
