Self-Hosting Trading Bots: Why I Ditched the Cloud

I run four live trading bots. They execute trades across prediction markets, forex, crypto, and DeFi. They run 24/7, handle real money, and they cost me exactly $0 per month in cloud infrastructure.

No AWS. No GCP. No Azure. No DigitalOcean. Just hardware I own, sitting in my home, drawing about as much power as a light bulb.

The Cloud Cost Problem

When I first started building trading bots, I deployed them the "right" way — on cloud VMs. A small instance for each bot, maybe $15-30/month per service. Seems cheap until you add it up: four bots, a database, monitoring, and suddenly you're spending $100-150/month for infrastructure that's essentially idle 95% of the time.

Trading bots are mostly waiting. They check conditions, evaluate signals, and occasionally execute a trade. The actual compute is trivial. You don't need a cloud server for that — you need something that stays on and stays connected.

That's a fundamentally different requirement than what cloud computing is designed for. Cloud pricing optimizes for burstable, elastic workloads. Always-on, low-compute workloads are the worst possible use case for cloud economics.

The Self-Hosted Setup

My entire infrastructure runs on a NAS device — a compact, low-power box designed for 24/7 operation. It draws minimal power, has redundant storage, and runs Docker containers for each bot. Total cost: the one-time hardware purchase. No monthly bills. No surprise charges. No vendor lock-in.

Each bot runs in its own Docker container with its own configuration and logs. They're isolated from each other — one bot crashing doesn't affect the others. I can update, restart, or redeploy any individual bot without touching the rest.

Monitoring happens through Discord. Every bot sends structured alerts when something noteworthy happens: trade executed, error encountered, daily performance summary. I open Discord in the morning and I can see exactly what happened overnight across all four systems.

The Real Advantages

Latency. My bots talk directly to broker APIs from a residential connection. No extra network hop through a cloud data center. For most retail trading, this doesn't matter much — but for webhook-driven execution where seconds count, less latency is always better.

Data sovereignty. My trading strategies, API keys, and financial data never leave hardware I physically control. No cloud provider employee, no misconfigured S3 bucket, no third-party breach can expose my systems. For trading infrastructure, this matters more than people realize.

Simplicity. No IAM roles, no security groups, no VPC configuration, no SSH key management across multiple cloud instances. I plug in hardware, deploy containers, and it works. When something breaks, I'm debugging my code — not cloud infrastructure.

Economics over time. The hardware pays for itself in 4-6 months compared to equivalent cloud costs. After that, it's pure savings. Over two years, we're talking about $2,000+ in avoided cloud bills. That's significant for a solo operation.

When NOT to Self-Host

Self-hosting isn't always the right call. If you need geographic distribution (running bots close to exchange servers in different regions), cloud makes sense. If you need to scale rapidly — processing thousands of signals per second — cloud elasticity is valuable.

If you're running a team and need shared infrastructure with proper access controls, managed cloud services reduce operational overhead. And if uptime is absolutely critical (like, regulated-exchange market-making), you want the redundancy guarantees that cloud providers offer.

But for most independent traders and small operations running a handful of bots that need to be always-on and reliable? Self-hosted hardware is the pragmatic choice. The cloud is rented infrastructure optimized for someone else's use case. Own your stack when you can.

Getting Started

You don't need anything fancy. A NAS device, a Mini PC, or even a Raspberry Pi can run most trading bots without breaking a sweat. Docker makes deployment reproducible. A UPS keeps things running through short power outages. And a simple backup script protects against hardware failure.

The total investment is comparable to 4-6 months of cloud hosting. After that, every month is free. If your bots are running 24/7 and you're tired of paying rent on someone else's computer, it might be time to bring them home.
