Data Flow

1. Trades Service → Connects to cryptocurrency exchange WebSocket, streams live trade data
2. Candles Service → Aggregates trades into OHLCV (Open, High, Low, Close, Volume) candlesticks
3. Technical Indicators → Calculates technical indicators from candles for feature engineering
4. Predictor Service → Trains and runs ML models on enriched data, produces predictions
5. Prediction API → Exposes REST endpoints for accessing real-time predictions

uv run pytest

# Run tests for specific service
uv run pytest services/trades/tests

# Run with coverage
uv run pytest --cov=services --cov-report=html

📊 Monitoring

Logging

All services use structured logging with Loguru:

from loguru import logger

logger.info("Processing trade", symbol="BTC/USDT", price=50000.0)

Metrics

• MLflow tracks model performance metrics
• Kubernetes metrics via Prometheus
• Custom application metrics exposed at /metrics

☸️ Kubernetes Deployment

Development (Kind Cluster)

# Create kind cluster
kind create cluster --name rwml-34fa

# Deploy service
make deploy-for-dev service=trades
