Complex Event Processing

Page 219 of 220 · Algorithm reference notes

Overview

This guide covers complex event processing implementation in automated trading systems. The approach combines established patterns with operational considerations drawn from production deployments.

Common Issues

Common issues with complex event processing include look-ahead bias in backtesting, overfitting to historical regimes, inadequate handling of exchange downtime, and insufficient logging for debugging.

Important: Always validate complex event processing logic on out-of-sample data before live deployment. Paper trading reveals execution issues that backtests miss.

Configuration Example

Configuration for complex event processing uses YAML or JSON format. Key parameters include timeframes, signal thresholds, position sizing rules, and risk limits.

# Example configuration for Complex Event Processing
strategy:
  name: complex-event-processing
  timeframe: 5m
  indicators:
    - rsi
    - ema_fast
    - ema_slow
  entry_conditions:
    - rsi_oversold
    - ema_crossover_bullish
  exit_conditions:
    - rsi_overbought
    - stop_loss_hit
  risk:
    max_position_size: 0.02
    stop_loss_pct: 0.015

Code Structure

The code structure separates concerns: data ingestion, signal generation, risk checks, and order submission. This modularity enables testing and reuse across strategies.
