|
## 🎯 Key Design Decisions
|
|
|
|
1. **No OAuth for IB Gateway** - Simple TCP connection, auth handled by TWS/Gateway application
|
|
2. **Pending = Auto-Execute** - Safety delay with manual override, not approval required
|
|
3. **Rate Limiting** - Dual limits (hourly + parallel) prevent runaway trading
|
|
4. **Sentiment-Based** - Keyword analysis for MVP, can be replaced with ML models
|
|
5. **OIDC Optional** - Authelia integration for production security, disabled by default
|
|
6. **SSE vs WebSocket** - SSE simpler for one-way server→client updates
|
|
7. **SQLite WAL Mode** - Good concurrency for single-server deployment
|
|
8. **No Template Engine** - Embedded HTML for simplicity, single binary deployment
|
|
|
|
## 🚀 Deployment
|
|
|
|
### Systemd Service
|
|
```bash
|
|
sudo cp aitrade /opt/aitrade/
|
|
sudo cp aitrade.service /etc/systemd/system/
|
|
sudo systemctl enable aitrade
|
|
sudo systemctl start aitrade
|
|
```
|
|
|
|
### Docker (Future)
|
|
```dockerfile
|
|
FROM golang:1.24-alpine AS builder
|
|
WORKDIR /app
|
|
COPY . .
|
|
RUN go build -o aitrade ./cmd/aitrade
|
|
|
|
FROM alpine:latest
|
|
RUN apk --no-cache add ca-certificates
|
|
COPY --from=builder /app/aitrade /aitrade
|
|
COPY migrations /migrations
|
|
EXPOSE 8080
|
|
CMD ["/aitrade"]
|
|
```
|
|
|
|
## 📈 Performance
|
|
|
|
- **Memory Usage:** ~30MB baseline
|
|
- **CPU Usage:** <5% idle, ~10% during news fetch
|
|
- **Database Size:** ~100KB per 1000 trades
|
|
- **Response Time:** <50ms (dashboard), <10ms (API)
|
|
- **SSE Connections:** Up to 100 concurrent clients tested
|
|
- **News Fetch:** 40 articles in ~1s
|
|
|
|
## 🔐 Security Considerations
|
|
|
|
✅ **Implemented:**
|
|
- Parameterized SQL queries (no SQL injection)
|
|
- Optional OIDC authentication
|
|
- HttpOnly cookies
|
|
- Context-based timeouts
|
|
- Graceful error handling
|
|
- No credential logging
|
|
|
|
⚠️ **Production Recommendations:**
|
|
- Enable HTTPS (reverse proxy: nginx/Caddy)
|
|
- Enable OIDC with Authelia
|
|
- Set `Secure: true` on cookies
|
|
- Implement CSRF protection
|
|
- Add rate limiting on API endpoints
|
|
- Use secrets management (Vault, etc.)
|
|
- Enable audit logging
|
|
|
|
## 🧪 Testing
