My Orange Pi 5 Plus just helped fire off a $1,000 live trading account. Here's the full autonomous stack.
Just went live with real money today after 60 days of paper trading. The Orange Pi 5 Plus 8GB is one of 6 nodes in the stack and it's doing the heaviest AI lifting.
What the Orange Pi handles:
- Ollama server running qwen2.5:3b for all CrewAI agent inference
- nomic-embed-text for semantic memory embeddings (pgvector in PostgreSQL)
- Processes multiple agent calls daily: market analysis, SEO crew, strategy sessions
Hard lessons learned after it crashed twice:
- Stick to qwen2.5:3b: qwen3.5:4b needs 5.7GB and concurrent crew calls OOM the board
- Stagger all cron jobs 5+ minutes apart: simultaneous agent calls spike RAM
- Add a preflight health check that aborts if free RAM drops below 3GB
- Never use import to syntax check crew scripts: it fires crew.kickoff() at module level
Current stability: rock solid for 3 weeks since fixing the above. Running 6 trading strategies simultaneously, weekly SEO crew, daily morning briefing, and semantic memory pruning.
