Getting Started

Prerequisites

  • Interactive Brokers account (paper or live)
  • TWS or IB Gateway installed
  • Python 3.8+ with ib_insync library
  • API permissions enabled in TWS

Quick Start

  1. Read IBKR Python API Introduction
  2. Set up TWS/Gateway with API access
  3. Connect to paper trading account
  4. Test with market data requests
  5. Implement basic order execution

Best Practices

  • Use Paper Trading: Test strategies before going live
  • Error Handling: Robust error handling for disconnections
  • Rate Limiting: Respect IBKR’s API rate limits
  • Risk Management: Implement stop-losses and position limits
  • Monitoring: Log all API calls and responses
  • Failover: Handle connection failures gracefully

Common Integration Patterns

Real-time Data Pipeline

IBKR API → Data Processing → Redis/DB → Analytics → UI

Automated Trading Loop

Market Data → Strategy Logic → Order Generation → IBKR API → Execution

Compliance & Risk

  • Paper Trading First: Always test with paper account
  • Position Limits: Enforce maximum position sizes
  • Daily Loss Limits: Circuit breakers for protection
  • Audit Trail: Log all trading activity
  • Compliance: Follow regulatory requirements
